Introduction to the chain of infection16,17,18,19,20
The way by which infection is spread can be thought of as a continuous chain
with 6 links (
see Table 1). In order to prevent infection or stop it spreading,
one or more links in the chain must be broken. This can be achieved through
practising standard infection control precautions.
Link 1
Sources of micro-organisms.
The main types of organism causing human infection include bacteria (e.g.
salmonella), viruses (e.g. hepatitis A, B or C), fungi, or yeasts (e.g. candida).
Infected people may act as a source of infection for others because the micro-
organisms may be found in certain body fluids and could be passed on to
others.
Link 2
Reservoirs for micro-organisms.
These are places where the organism may live and survive. Reservoirs can
include people, animals, the environment, food or water. Contaminated food
may act as a reservoir, for example if it is contaminated with salmonella or
campylobacter. If the meat is not thoroughly cooked, those eating it may
become infected. Other examples of reservoirs for micro-organisms include
articles such as towels, flannels, wash bowls, bed pans, contaminated
equipment etc.
Link 3
The way microbes leave the body
Sometimes termed “portal of exit”, this can occur in a number of ways. For
example, salmonella leaves the body in the faeces and, if diarrhoea is
present, high numbers of salmonella microbes are excreted. Tuberculosis
uses the same entry and exit point in that it is inhaled and exhaled.
Link 4
The method of spreading microbes from person-to-person
Infections are spread in several ways, depending upon the infection. These
include direct or indirect contact (including ingestion, sexual contact, mother
to foetus, injection or inoculation) and some infections are airborne and are
inhaled, e.g. pulmonary tuberculosis.
Unwashed hands are the most common way to spread infection. Microbes may be present in any body fluids (excreta and secretions). If hands
come into contact with body fluids they may be carried from one person to
another unless the hands are washed. In addition the microbes can be
spread from person-to-person via a contaminated environment (e.g. dust) or
equipment.
Some infections may be spread via the air, such as the cold and flu viruses.
The infection may be spread in droplets or airborne spray produced by
coughs and sneezes. Some childhood illnesses may also be spread in this
way.
Link 5
A susceptible person (person at risk of infection)
People are at risk of developing infection if they are in contact with the
organism in sufficient numbers to cause illness. Immunity to some infections
can be developed after being infected (e.g. chickenpox) or after immunisation
(e.g. hepatitis B).
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 2 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
Certain people are more susceptible or at greater risk of infection for a variety
of factors. People who are very young or the very old are more at risk
because their immune system may not be developed or may be waning. In
addition, some medications, such as steroids and cytotoxic agents can
increase infection risk. So can underlying diseases such as diabetes, blood
disorders or cancer.
Link 6
Microbes enter into the body
Sometimes termed “portal of entry”. In order for microbes to cause infection
they must gain entry into the body. Different organisms have different ways
of entering our bodies. For example, salmonella need to be ingested (eaten).
Some organisms may cause infection if they are inhaled e.g. tuberculosis.
Others, such as hepatitis B, enter the bloodstream via broken skin, injection
or sexual intercourse.
Breaking the chain of infection
Breaking the chain of infection by targeting one or more links can halt the
spread of infection. This usually involves:
a)
Eradicating the source of infection through appropriate antimicrobial
therapy
b)
Preventing the method of spread through hand washing, hygiene,
disposal of waste, decontamination of equipment etc or
c)
Protecting the individual at risk by immunisation
d)
Preventing microbes from entering the body by wearing protective
clothing, using an aseptic technique when handling invasive devices,
covering wounds and insertion sites with sterile dressings etc.
It is impossible to identify everyone who is infectious to others. Some
diseases are infectious before any signs develop, such as chickenpox. Some
infections may not show any signs or symptoms, such as hepatitis B or HIV.
Also some people may be carriers without developing the infection
themselves, e.g. salmonella or MRSA.
For this reason it is important that everyone carries out infection control
precautions at all times, regardless of whether infection is present or
suspected. In the home it may not always be possible to practice standard
infection control precautions to the same standard as in a clinical setting. In
addition in the home the risks of infection and its spread may be less than that
in a clinical environment.
Standard infection control precautions include:
• Hand
hygiene
• Use of protective clothing and equipment
• Cleaning and disinfection of equipment and the environment
• Disposal
of
waste
• Food
hygiene
• Laundry
• Management of inoculation injuries (bites/ and injuries with sharps and
body fluids)
• Management of invasive devices and wounds (

B 1.0 Hand
hygiene13,15,16,17,18,19,20,21,22,23,24,25,153
Hand hygiene is widely recognised as the most important method of
preventing infection and cross infection. In order to support the important role
hand hygiene plays in maintaining patient safety, Swindon PCT have
implemented the National Patient Safety Agency (NPSA) clean
yourhands
campaign
The purpose of hand hygiene is to remove or destroy any bacteria picked up
on the hands (transient bacteria). In some situations (e.g. prior to invasive
procedures) it is necessary to also reduce the numbers of bacteria that
normally live on the skin (resident bacteria). This prevents their being
transferred to other people, while at the same time protecting oneself. A good
hand washing technique is as important as the kind of product used.
B 1.1 Hand hygiene facilities15
B 1.1.1 Clinical settings
Hand washing must be carried out using running water at a comfortable
temperature. Clinical hand washbasins should be provided wherever clinical
care is being given, e.g. service users’ rooms in care homes, wards,
treatment rooms, dirty utility rooms and kitchens. A clinical hand washbasin
consists of lever-operated mixer taps, with no plug and no overflow. If mixer
taps are not available for any reason a thermal control can be added to the
hot tap to provide warm running water. In care homes, staff should also be
able to wash their hands under warm running water.
Liquid soap should be used for hand washing. This should be provided in
wall-mounted dispensers with disposable cartridges or disposable pump-
action bottles. Re-fillable cartridges are not recommended. Dispensers must
be kept clean and replenished.
Aqueous antiseptic solutions or alcohol hand rubs/gels may also be used.
Alcohol hand rubs/gels may be used as an alternative to soap and water, if
the hands are visibly clean. They are particularly useful in situations where
hand washing may not be convenient.
Hand creams may be used to help protect hands from soreness. This must
be supplied as individual tubes or in a pump-action container. Communal
pots must not be used.
Disposable paper towels must also be available at all hand wash basins in
clinical settings, including toilets and kitchens. Communal (e.g. cotton) towels
are not recommended in clinical settings. Foot-operated waste bins must be
used for disposal of paper towels. Don’t use hands to raise the lid.
B 1.1.2 Clients’ homes
In clients’ own homes the hand hygiene facilities may not be ideal. Staff
visiting clients at home should carry a supply of alcohol free skin cleansing
wipes and alcohol hand rub/gel. These products may be used instead of
hand washing if facilities are inadequate. Alcohol hand rub/gel should be
used on visibly clean hands and when hand disinfection is needed. Certain
hand hygiene practices can increase the risk of skin irritation and should be
avoided. For example, washing hands regularly with soap and water
immediately before or after using an alcohol-based product is not only
unnecessary, but may lead to dermatitis
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 5 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
Staff should use pump-action liquid soap dispenser rather than bar soap. Dry
hands using paper towels or, if these are not available, use paper roll or a
clean cotton towel.
B 1.2 Routine hand hygiene
The aim of routine hand hygiene is to remove dirt and most removeable
(transient) micro-organisms found on the hands. It is carried out in at least
the following circumstances:
•
Before starting work and going home
•
After contact with body fluids e.g. dealing with incontinent clients
•
After removing personal protective equipment (PPE)
•
Before and after giving care
•
After using the toilet
•
Before eating and handling preparing food
•
After handling pets
•
After handling raw food
•
After handling refuse and clinical waste
•
When hands look or feel dirty
•
After any cleaning activities
Before starting work, wash any broken or cut areas of exposed skin and cover
with a waterproof dressing.
For routine hand hygiene the technique is as important as the solution used.
•
Remove hand and wrist jewellery and wristwatches, and roll up
sleeves. Wedding rings without stones may be left in place
•
Wet hands under warm running water
•
Apply liquid soap
•
Rub this into all parts of the hands vigorously, without applying more
water, using the 6-step technique (
see Table 2) for at least 10-15
seconds
•
Rinse hands under running water
•
Dry thoroughly using paper towels
Alternatively:
If hands are clean, apply sufficient alcohol hand rub/gel, to rub into all parts of
the hands using the 6-step technique, until the alcohol has evaporated.
Washing hands with soap and water is required after contact with patients
with diarrhoea, because alcohol is less effective on micro-organisms such as
Clostridium difficile and viral causes of gastroenteritis.

2nd Edition (2007)
B 1.3 Hand disinfection
The aim of hand disinfection is the destruction of transient micro-organisms
and a reduction in resident organisms. It is carried out in at least the
following circumstances:
•
Before invasive or aseptic procedures
•
After contact with people with known or suspected infection
Any fresh abrasion, cut etc. on the hands should be covered with a
waterproof dressing or appropriate barrier e.g. gloves.
There are two ways of performing hand disinfection:
•
Wash hands as above using liquid soap, then apply sufficient alcohol
hand rub/gel and rub into all surfaces of the hands until dry. Alcohol
hand rub/gel can also be used between cases if the hands are socially
clean.
Or
•
Wash hands as above using an aqueous antiseptic solution (e.g. 4%
chlorhexidine-detergent or 0.75% povidone/iodine detergent). Lather
all aspects of the hands and wrists using the 6-step technique for 2
minutes.
Table 2 Hand hygiene technique21,22

HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 2.0 Client’s Personal Hygiene 4,5,145
B 2.1 Washing and bathing
•
Clients should have their own toothbrushes, razors, face cloths, soap,
lotions, creams etc. Communal items can spread infection.
•
Separate cloths must be used for cleaning of the client’s face/body
and their genital/anal areas. Disposable cloths could be used instead.
•
Antiseptics or salt should not be added to the bath water as they have
little or no beneficial properties.
•
Daily bathing, shower, or a full body wash is best to prevent an
accumulation of dirt and bacteria on the skin. This is particularly
important for those who are incontinent.
•
Baths should be cleaned regularly with warm water and detergent or
cream cleanser. It is not usually necessary to add disinfectants.
•
In community hospitals or residential care settings wash bowls should
be individualised if possible. Alternatively the bowls must be cleaned
and dried thoroughly between uses.
B 2.2 Mouth care25,26
•
The most effective method of keeping the mouth clean, moist and free
from infection is to brush the teeth/gums with a soft toothbrush and
toothpaste after meals. Disposable foam sticks may be used if the
individual cannot use a toothbrush.
•
Frequent sips of water can also keep the mouth fresh and clean, if
drinking is inadequate
•
Liquid paraffin e.g. Vaseline, may be used to moisten the lips
•
If the client produces too little saliva, 2-3 spays of artificial saliva can
be sprayed inside the mouth up to 4 times daily
•
Antiseptic mouthwashes have a limited effect on mouth organisms and
should not be used routinely
•
Dentures should be cleaned using a proprietary denture cleaner
•
Denture pots must be individualised
•
Removable braces must be cleaned daily
•
Keep toothbrushes clean and dry, replace periodically.
•
Regular dental checks can help to identify and prevent mouth
conditions.

HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 2.3 Eye care25
Special precautions are only needed if the eyes are damaged or after eye
surgery. In these cases, if eyes require cleaning, this should be performed
using a low-linting swab, moistened with either normal saline or cooled boiled
water.
Hands should be washed prior to giving eye care. The eyes should be wiped
from the nose outwards, using a new piece of cotton wool or lint for each
‘wipe’.
Eye drops/ointment should only be used if they have been prescribed and
have not past the expiry date. Ensure there is good lighting. Hands must be
washed prior to instilling medications. The patient should have their head
well supported and tilted back. Most eye medications are instilled just inside
the lower eyelid. The outlet of the tube or bottle must not be allowed to touch
the skin or eye.
B 2.3.1
Care of artificial eyes
If the client's own eye has recently been removed, Chloromycetin ointment
may be prescribed, and should be administered according to the instructions.
Once the socket has settled, the false eye and socket should be cared for as
follows:
•
The eyelids should be kept clean by bathing or wiping with cotton wool
or soft lint moistened with normal saline or cooled boiled water.
•
If the false eye has become dirty, it should be cleaned in normal saline
or cooled boiled water.
• On
no account should the eye be washed in any type of detergent, as
this may cause irritation to the socket and surrounding skin.
B 2.4 Ear care
Ears should be kept clean and dry and examined periodically for signs of
infection. Items such as cotton buds should not be used to remove wax from
the ears. The removal of wax can be promoted by chewing. If a build up of
wax in the ear is noted it may be worth instilling a few drops of wax remover,
following the manufacturer’s directions.
Only health care professionals who have received training in the irrigation
(syringing) of ears, and are deemed to be competent, may undertake this
procedure. Usually individuals who need to have their ears syringed are
referred to their local general practice. Mechanical ear syringing machines
are now recommended and metal syringes should not be used.
Further advice on ear care can be obtained by visiting the website of the
Primary Ear Care Centre: www.earcarecentre.com. See the website or
Table
6 for details on how to decontaminate ear syringing machines.
B 2.4.1
Cleaning “behind the ear” hearing aids
•
Separate the hearing aid from the ear mould by pulling the flexible
tubing away from the hooked part of the hearing aid. Take care not to
pull the tubing out of the ear mould. If the tube is stiff, do not force it.
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 9 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
•
Wash the ear mould and flexible tube in warm soapy water (not
detergent or cleaning liquid). A brush can be used to remove any wax
from the tube.
•
Rinse the ear mould in clean water. Dry the tubing and ear mould by
tapping gently onto a tissue held in the hand to remove drops of water.
Ensure no droplets remain.
•
Leave the ear mould and attached tubing to dry in a warm (not hot)
place
•
Once the ear mould and tubing are dry, reattach to the aid
•
Contact the local audiology department for further information.
B 2.5 Foot care27,28
Good foot care is essential to ensuring the health of the feet and preventing
wounds and disease of the feet. In care homes residents tend to be at
special risk especially during times of immobility, during which pressure-
relieving devices must be used. Certain individuals are at increased risk of
foot disease, including people with diabetes, neuropathy and ischaemic
disease.
Good fitting shoes can help promote healthy feet for all clients. Footwear
needs to:
•
Be worn – not kept for best and going out
•
Be made of soft non-occlusive material with no seams or knots
•
Have light-weight and shock-absorbing soles with a cushioned insole
•
Be of the correct length, width and depth
•
Have a broad fronts with plenty of toe room and a soft padded heel
cuff
•
Hold the foot steady by means of good laces, buckles or Velcro
fastening
•
Be fitted by a trained fitter with the client standing
The following measures will also help to promote healthy feet and prevent
injury.
•
Examine the feet regularly (preferably daily especially in high risk
groups)
•
Ensure the shoes fit correctly
•
Those at risk of foot disease should avoid walking in bare feet
•
Wash feet daily using warm water and mild soap
•
Dry thoroughly, but not roughly, especially between the toes
•
Change socks and hosiery daily
•
If the skin is dry, apply hand cream or moisturising cream to the heels
and balls of the feet
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 10 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
•
Cover any cuts with a sterile dressing and report to a State Registered
Chiropodist if in a high risk group
•
Trim nails regularly, following the natural shape of the toe. Do not cut
down the sides
•
Carers should not trim the nails of people in high risk groups, unless
they are deemed competent by a State Registered Chiropodist
•
Clients should be able to see an NHS chiropodist free of charge,
providing they have a medical or podiatry need. Check with the local
NHS Podiatry Service for access criteria and available services.
•
To prevent the spread of infection, individual clients should have their
own nail clippers and nail files.
•
People with diabetes should have a risk assessment carried out at
least annually by a registered health professional
•
Don’t cut corns, calluses or in-growing toenails
B 2.5.1
Diabetic foot ulcers27,28
Diabetic foot ulcers need to be assessed at least once a year and treated
appropriately, so refer to a specialist clinic. Good fitting shoes can help avoid
foot ulcers, see the notes above.
The hospital-based chiropodists/podiatrists and orthotists may have a range
of information leaflets and may offer training.
Inadequate assessment, and failure to implement preventative measures,
may result in unnecessary amputation.
Improve general health and circulation by:
• Controlling
diabetes
• Reducing
cholesterol
•
Treating high blood pressure
• Stop
smoking
•
Observe for changes in the feet (cuts, bruises, blisters, redness,
corns, calluses, verrucas) and seek professional advice

B 3.0 Protective
clothing/equipment13,29,30,153
Protective clothing is an essential part of health and social care. It provides
protection from micro-organisms for both carers and clients. It is used to
protect the skin (and sometimes airway or mucous membranes) from contact
with blood and body fluids, and also protects clothing from contamination.
The use of protective clothing should be based on an assessment of the risk
of spread of micro-organisms from person to person and the risk of
contamination of the carer’s clothing or skin.
B 3.1 Disposable gloves30
A range of appropriate gloves should be available and accessible to staff
(Table 3)
•
Gloves are to be worn whenever contact with body fluids, mucous
membranes or non-intact skin is anticipated
•
Gloves are not to be worn as an alternative to hand hygiene
•
Gloves should be changed after each procedure and hands washed
following their removal
•
To remove glove: grasp wristband and pull forwards over the hand and
fingers, inverting the glove. Avoid contaminating the skin
•
Washing gloves with soap and water or alcohol should not be
undertaken, because this may not be effective and may damage the
glove
•
Gloves should be seamless, well fitting and powder-free.
•
A latex-free glove should be available for anyone who has a latex
allergy

B 3.2 Aprons/gowns
These are worn to protect the clothing from contamination. The decision to
wear an apron is based upon an assessment of the risk of contamination with
body fluids e.g. diarrhoea. They are single use and should be changed
between tasks, then discarded appropriately. Colour coding of the aprons can
be useful, though not essential. An example of this may be:
Blue
food handling and feeding
White
general uses
Red
in wards and communal settings, when caring for clients with
infection
Examples of when they should be worn:
• During
bathing
•
When helping clients in the toilet
•
When cleaning equipment, sanitary equipment and environment
•
During bed making
•
During food handling
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 13 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
Full-length, long-sleeved, fluid-repellent gowns should be worn when there is
a risk of gross contamination with body fluids, e.g. assisting during childbirth
or caring for a patient in isolation with highly contagious diseases such as
Severe Acute Respiratory Syndrome (SARS).
B3.3 Masks, visors, eye protection
These are worn when a particular procedure is likely to cause splashing of
blood, tissues or chemical into the eyes, face or mouth.
A high-efficiency, particulate filter mask (known as a respirator) should be
worn when caring for a client who is known to have sputum smear positive
(open) tuberculosis of the lung or SARS. These can be obtained via supplies,
directly from the manufacturer or, in an emergency, from the chest unit at the
local district general hospital. Advice on whether it is necessary to wear a
mask can be obtained from the Health Protection Unit or the local clinical
team responsible for the care of the client.
B 3.4 Uniforms
•
Uniforms do not constitute protective clothing
•
During the course of the working day uniforms will become
contaminated with micro-organisms
•
Uniforms should be protected from gross contamination by the use of
disposable aprons.
•
Uniforms should have short sleeves and should not be fitted with
buttons.
•
The material should be able to withstand a wash temperature of 60oC.
•
Staff should change into normal clothing at the end of the working day.
•
If wearing uniform to and from work is unavoidable, cover uniform with
an outer layer
•
A sufficient supply of uniforms should be provided so that a clean
uniform can be worn every day
•
If staff wear their own clothes in the workplace similar hygiene
measures should be employed.

B 4.0 Cleaning/decontamination of the environment29,31, 129, 131, 153
B 4.1 Introduction
In general, it is considered that the environment has a relatively low role in the
transmission of infection. However the environment is known to play an
important role in cross infection during outbreaks. Door handles, flush
handles, taps etc have all been implicated. Therefore, special attention must
be played to these fittings during outbreaks.
In addition, accumulations of dust, dirt and liquid residues will increase
infection risks and must be reduced to the minimum. This can be achieved by
regular cleaning and by using good design features in buildings, fittings and
fixtures. Contact the Health Protection Unit / Infection Control Team for
advice.
An audit programme for monitoring the standard of hygiene should be in
place in all community hospitals and residential care settings.
B 4.2 Clinical settings
A written cleaning schedule should be devised, based on a Control of
Substances Hazardous to Health29 (COSHH) assessment, which includes the
management of spillage of body fluids and regular removal of dust by damp
dusting high and low horizontal surfaces. This should specify the persons
responsible for cleaning (especially in the cleaner's absence), the frequency
of cleaning and methods used and the expected outcomes.
Work surfaces and hard floors should be smooth-finished, intact, durable, of
good quality, washable, should not allow the pooling of liquids and be
impervious to fluids.
Carpets are not recommended in treatment rooms or other clinical areas likely
to be regularly contaminated with body fluids. Where carpets are provided
there should be procedures or contracts in place for regular cleaning and for
dealing with spillage. Curtains should be cleaned when soiled or periodically
(e.g. six monthly) and an adequate supply of curtains purchased to facilitate
this.
B 4.3 Client’s own homes
The main aim of hygiene in the home is to target those places where
pathogenic microbes may reside and have the potential to cause infection,
e.g. toilets, kitchens and spillages of body fluids. Normal cleaning methods,
such as vacuuming and damp dusting/cleaning surfaces, are generally all that
is required. If another member of the family, or an informal carer, lives there
be sure they know what you are doing and why. Tact may be needed as they
may feel the house is clean enough already, especially if they do the cleaning
normally.

HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 4.4 Cleaning materials
Disposable, non-shedding cloths or paper roll should be provided for cleaning
purposes. Equipment and materials used for general cleaning should be kept
separate from those used for the cleaning of body fluid spillage. Do not leave
cloths or mops stored in disinfectants or buckets. Colour coding of cleaning
equipment (cloths, mops, gloves) is advisable, for example:
Green
Kitchens only, never used elsewhere.
Blue
General areas e.g. offices, wards/departments
Yellow
Washbasins, washroom surfaces.
Red
High risk areas e.g. sluices, toilets, washroom floor
White
Isolation rooms, operating theatres and anterooms
Cream cleaner or a hard surface cleaner is usually suitable for cleaning hand
washbasins and general-purpose detergent is recommended for other
environmental cleaning. Follow manufacturer’s instructions. Wipes
impregnated with 70% alcohol can be used for those items that cannot be
immersed e.g. electrical equipment. A COSHH assessment is required for
any cleaning materials used.
For suggested methods and frequencies of cleaning the environment and
equipment, refer to
Table 6.
B 4.5 Management of the spillage of blood and high-risk body fluids11
Spillages of blood and high-risk body fluids must be dealt with quickly and
effectively. Disposable gloves and an apron must be worn and in clinical
settings the contaminated debris treated as clinical waste. In domiciliary
settings the waste should be contained in a plastic bag that is securely tied
and discarded in the household waste.
Chlorine-releasing agents can be a hazard especially if used in large
volumes, in confined spaces or mixed with other chemicals or urine.
Protective clothing must be worn and the area well ventilated. A risk
assessment and COSHH assessment must be carried out if using these
chemicals. Increased risk is related to the likelihood of infection. Following a
risk assessment and depending upon the products available, spillage may be
dealt with by any of the following methods.

Cleaning/decontamination of equipment29,32-52, 146, 153
The decontamination of medical devices has been the subject of a number of
Health Service Circulars (HSC1999/179 and HSC 2000/032). All NHS
premises must comply with the National Decontamination Strategy by 31
March 2007, monitored by the Healthcare Commission. Options include:
•
Centralise all decontamination to an accredited Sterile Services
Department
•
Use only single-use devices
•
Undertake decontamination locally to all applicable standards
•
A combination of the above

Items in contact with intact skin are classed as
low risk and should be
cleaned.
•
Items in contact with mucous membranes (eyes, mouth or rectum) are
classed as
medium risk and at least disinfected between uses
.
•
Items that enter the body or have contact with broken skin, broken
mucous membranes or with the vagina37 are classed as
high risk and
must be single use or sterilised.

B 5.2 Cleaning29,32-36
Thorough cleaning with detergent and/or enzymatic cleaner and warm water
(body temperature) will remove large numbers of micro-organisms from a
surface, especially if the article can be rinsed. A further reduction in numbers
occurs as the surface dries. Devices cannot be effectively disinfected or
sterilised without having first been thoroughly cleaned and dried. Cleaning
will not be effective if surfaces are damaged or rusty.
An automated method such as a thermal washer/disinfector is the most
effective cleaning method and is recommended for cleaning all medical
devices including surgical instruments.
B 5.2.1
Washer-disinfectors32,35
Thermal washer-disinfectors physically clean devices and kill micro-
organisms by applying hot water at disinfection temperatures. They are used
for cleaning instruments, bedpans, urinals and other devices. They must
have a contract for planned preventive maintenance and must be cleaned
and maintained in accordance with Health Technical Memorandum (HTM)
203035. Daily records must be kept of the cycle.

HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 5.2.2
Ultrasonic washers32,35
Ultrasonic washers are not recommended for use in NHS premises. If used:
•
Ultrasonic cleaners must be used in accordance with manufacturer’s
instructions and HTM 2030.
•
The lid must be on when operated to avoid the dispersal of aerosols
and to protect users from noise.
•
These cleaners cannot be used for plastic or similar materials
•
Cannulated instruments can be used in ultrasonic washers, but must
also be flushed or brushed with cleaning solution, or attached to a
nozzle on the washer
•
Check with the manufacturer that the washer is suitable for the items
to be cleaned
•
Hinged items should be opened before loading in the washer
•
Remove gross contamination and soiling from devices before loading
•
A low foaming surfactant or detergent should be used in the washer
•
Fill with clean water and the required volume of detergent prior to use
•
Bring up to the operating temperature and operate for at least 5
minutes to de-gas the solution
•
After de-gassing load the washer and replace the lid
•
Once clean (after the recommended time) remove the basket and
rinse instruments in very hot water (at least 600 C) before drying
•
Empty the tank after 4 hours, or when visibly soiled, or at the end of
the session, whichever is soonest. Clean and dry.
B 5.2.3
Manual cleaning32,36
Medical devices and instruments must not be cleaned by hand although this
is an acceptable method for cleaning the environment and low risk patient
equipment such as beds, commodes etc. A risk assessment and records of
agreed procedures must be in place to ensure that a consistent method is
employed by all staff. Disposable gloves and apron are advised, and the use
of enzymatic cleaners or detergent and warm water (not exceeding 350 C).
Avoid generating splash by immersing the item where possible. If splash is
unavoidable wear protective eyewear. After cleaning, rinse and inspect the
equipment. If the item remains soiled, repeat the cleaning process. Ensure
the item is dried as quickly as possible either using paper roll or by inverting
to air-dry.
B 5.2.4
Cleaning materials
Cleaning equipment (brushes, mops etc.) must be kept clean and dry
between uses. Re-usable cloths are not recommended.

B 5.3
Disinfection32
Disinfection is a process used to reduce the number of micro-organisms to a
level that is considered safe, but which may not necessarily destroy some
viruses or bacterial spores. Disinfection is usually acceptable for devices that
pose a medium risk of infection if these devices cannot be effectively
sterilised. Disinfection can be achieved in a number of ways including the
use of heat and chemical disinfectants. Both methods have their drawbacks
and it is often safer and more convenient to use a disposable device instead.
Further advice can be obtained from the publication
Guidance on
Decontamination, prepared by the Microbiology Advisory Committee to the
Medical Devices Agency. It is available on a CD-ROM and on the Medicines
and Healthcare Products Regulatory Agency’s website: www.medical-
devices.gov.uk.
B 5.3.1
Heat disinfection32
Dishwashers, washing machines and washer-disinfectors are effective
methods for disinfecting equipment because they clean the item and then
expose the items to hot water for the required time to achieve thermal
disinfection.
650 C for 10 mins
710 C for 3 mins
800 C for 1 min
900 C for 1 sec
Washer-disinfectors must be maintained in accordance with manufacturer’s
instructions and validated using HTM2030, with particular emphasis on
ensuring that the cleaning process is effective.
B 5.3.2
Chemical disinfection32,39,40
Chemical disinfectants can be toxic, flammable, corrosive or have other
material incompatibilities, so their use should be avoided wherever possible.
Even when laboratory tests have demonstrated the effectiveness of a
particular chemical to kill specific micro-organisms, in practice it may fail to do
so for a number of reasons. These include:
•
Inactivation of the disinfectant by a wide variety of substances, such
as organic matter (blood and body fluids), certain detergents, wood,
cork, plastics, rubber, some inorganic chemicals
•
Presence of organic material preventing the disinfectant from
contacting the surface of the object
•
Decay of a disinfectant and loss of efficiency due to time, temperature,
impurities, incorrect dilution
•
Incorrect contact time
Chemical disinfectants must be used at the correct dilution and the device
immersed for the correct length of time, depending upon the manufacturer’s
instructions. Disinfectants must also be suitable for the types of micro-
organisms targeted. A COSHH assessment must be undertaken when
selecting a chemical disinfectant in order to safeguard health.

B 5.3.2.1
Using a chemical disinfectant:32,40
•
Ensure the disinfectant receptacle is clean and dry
•
Ensure the device is clean and dry
•
Wearing protective clothing fill the receptacle with sufficient freshly
prepared disinfectant to allow complete immersion of the device
•
Immerse the device in the solution, ensuring there are no air bubbles
and that the disinfectant has contact with all surfaces including the
lumen of tubes
•
Cover the receptacle and leave for the correct length of time, using a
watch
•
Rinse the device in water of suitable quality, e.g. sterile water
•
Dry using clean, non-shedding cloth or paper
•
Wash, dry and disinfect or sterilise the receptacle before storing dry
B 5.3.2.2
Selecting a chemical disinfectant32,39,40
There should be very few reasons for using a disinfectant and, where
possible, disposables or sterilisation are recommended.
Disinfectants must be stored, reconstituted and used in accordance with
COSHH regulations.
Chlorine preparations39,40
These include Sodium hypochlorite and Sodium dichloroisocyanurate
(NaDCC). They usually are presented in the form of tablets, powders or
granules that are then reconstituted into the required concentration. In liquid
form they are less stable and have a shorter shelf-life. NaDCC releases
chlorine slowly and has a more prolonged effect than Sodium hypochlorite.
Chlorine preparations are corrosive to metals and inactivated by organic
matter, though NaDCC is less so than sodium hypochlorite. They should not
be used on urine as this may release chlorine vapour, which is hazardous.
Milton is often used for disinfecting infant feeding equipment and catering
equipment.
Examples:
Haz Tabs, Actichlor, Precept, Sanichlor, Milton

Alcohol preparations
Alcohol preparations are useful chemical disinfectants because they ready
diluted and can be used immediately. They are effective against most
bacteria and viruses, but have poor penetration. They are flammable so must
not be used near naked flames or sparks. They evaporate rapidly and can be
used on equipment that may be damaged by other methods of
decontamination. Disinfection occurs during evaporation of the alcohol, so
items must be dry before use. Examples include:
Ethanol, Industrial methylated spirit
70%
Isopropyl alcohol
60-70%
Alcohol impregnated swabs (Sterets) 70%
Alcohol hand rubs/gels

Chlorhexidine
Chlorhexidine is a skin disinfectant that is very effective at reducing
Staphylococcus aureus and other organisms found on the skin. It is often
used to decontaminate hands prior to invasive procedures such as minor
surgery. It is not suitable for cleaning equipment or the environment.
Examples include:
Hibiscrub
Hibitane
Combined detergent-disinfectants
Products are available that combine a detergent and a chlorine-based
disinfectant for use when cleaning the environment and in particular sanitary
equipment (baths, showers, toilets etc), especially used during outbreaks of
gastrointestinal infection. Examples include:
Titan Sanitiser, Chlorclean, Actichlor plus

B 5.4 Sterilisation32
Sterilisation is a process used to render an object free from all micro-
organisms.
It is recommended that sterile equipment should be obtained pre-sterilised
from a manufacturer or via a Central Sterile Supplies Department (CSSD).
Bench top steam sterilisers need intensive maintenance and rigorous controls
in place to ensure their effectiveness and their use should be restricted to
situations where CSSD or disposables are not available. The decision to use
bench top steam sterilisers should be accompanied by a risk assessment.
Systems and records must be in place to ensure that all staff employ
consistent methods and equipment is functioning effectively. NHS
organisations must be able to demonstrate compliance with the National
Decontamination Strategy by 31 March 2007 and the Healthcare Commission
will monitor compliance.
B 5.5 The use & maintenance of bench top steam sterilisers 32,41-49
The use of bench top steam sterilisers should be restricted to those situations
where it is not possible to utilise the services of the Central Sterile Supplies
Department. Users and owners must be aware of the legal implications in the
event of infection or untoward exposure that may result from procedures
using devices that have been processed incorrectly. Operators of sterilisers
must be suitably trained and the steriliser maintained and tested frequently to
ensure that it is achieving sterilising conditions consistently.
Where it is agreed that a bench top steam steriliser will be used, the model of
steriliser used must be appropriate for the load. A standard (downward
displacement) bench top steam steriliser is intended specifically to process
solid, unwrapped instruments without lumens. Vacuum (porous load) bench
top sterilisers may also be used to process wrapped loads and instruments
with lumens. The latter are expensive to buy and their cost of ownership is
high, because testing and maintenance is complicated and takes a long time.
The safe operation of steam sterilisers include:
•
Daily checks by the User and other periodic testing by a qualified test
engineer
•
Provision of clean steam by correct management of the reservoir and
chamber
•
Quarterly servicing and maintenance
• Correct
loading
•
Accurate record keeping and log book maintenance
•
Training of the operator
These are outlined below, but detailed guidance on the purchase, use and
operation of bench top steam sterilisers can be found in bulletins published by
the Medical Devices Agency 42,43. Health Technical Memorandum 201045
provides comprehensive guidance on all aspects of sterilisation and
sterilisation processes.
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 25 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 5.5.1 Purchase of a bench top steam steriliser
Those involved in the purchase of equipment should refer to MDA DB 2002
(06) 42 and must obtain the supplier’s assurance that the steriliser is suitable
for the loads that the user intends to process, because some machines have
limited function. For advice contact the Infection Control Team, an
Authorised Person (sterilizers) (contact details available from PASA –
www.pasa.nhs.uk) or Strategic Health Authority Decontamination Lead.
The processing of wrapped instruments and utensils, instruments with lumens
and the processing of porous loads cannot be carried out in standard bench
top steam sterilisers. Items such as these must be processed in a vacuum, or
porous load, steriliser that the manufacturer has validated for this type of load.
B 5.5.2 Installation and commissioning of a bench top steam steriliser42
After a steriliser has been installed, it must be checked and tested
(commissioned) by a properly trained and qualified test person who may be
employed by the manufacturer or a contractor. These checks and tests are
intended to demonstrate that the steriliser functions correctly and complies
with the specification. The test results must be recorded in the steriliser
logbook. A steriliser that has not been commissioned, or fails any test during
commissioning, or periodic testing, must not be used until the cause has been
identified and corrected. It must then be fully re-tested and fulfil all test
requirements satisfactorily before being used.
B 5.5.3 Logbook42 Each steriliser must have its own logbook, which provides a permanent
record of all testing, maintenance and repairs performed on the steriliser. It
must contain a record of all actions taken in the event of a failed cycle or a
failed test. The logbook may provide useful evidence in a case of litigation.
B 5.5.4 Testing and Maintenance42
The owner/user is responsible for daily/weekly testing, which are designed to
show that the operating cycle functions correctly.
See Table 5. Record all
observations in the logbook. An independent recording device can be fitted to
some types of steriliser and will provide a permanent record that can be kept
in the logbook. The observed values must be within the established time-
temperature limits for the cycle. A more comprehensive description is given
in MDA DB 2002 (06).
A Test Person (sterilisers) must conduct quarterly and annual testing.
Owners of bench top steam sterilisers must ensure that the steriliser is
subject to a planned and documented schedule of preventative maintenance.
The manufacturers will also advise on these aspects. HTM 2010 Part 3
provides comprehensive information on all aspects of testing bench top steam
sterilisers.

B 5.5.5
Indicators 32,42,49
Chemical and biological indicators play only a limited part in the validation and
routine control of steam sterilisers. They are regarded as supplementary to
the measurement of temperature, pressure and time. They may not
demonstrate sterility of the load and may serve only to distinguish loads that
have been sterilised from those that have not.
If chemical or biological indicators are used, they must be correctly selected
and used for the process specified by the manufacturer. The same applies to
the use of steam penetration test kits. Results must be recorded in the log
book.

Cleaning instruments prior to sterilisation32,36,42
Cleaning is an essential pre-requisite to effective sterilisation; the steriliser
does not wash or clean equipment. Dirty instruments placed in the autoclave
may not be sterilised as the contaminant may coagulate and form a barrier,
which the steam cannot penetrate. Such instruments must be regarded as
non-sterile and they must not be used until they have been cleaned
thoroughly and re-sterilised. (
See B 5.2).
A washer-disinfector is recommended for cleaning instruments. After
cleaning, instruments must be stored dry.
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc

HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 5.5.7
Loading the steriliser
Sterilisation relies on the contact of steam with all surfaces of the load for a
given period of time. Droplets of water may result in cool spots and corrosion,
and incorrect loading may prevent steam penetrating throughout the load.
Both will prevent sterilisation. Therefore:
•
Instruments must be dry when loaded into the steriliser
•
They must not touch each other
•
Bowls and receivers should be placed on edge. This will enable
steam to displace air upwards and downwards and prevent air
becoming trapped
•
Hinged instruments must be left open
•
The machine and baskets must not be overloaded
B 5.5.8
Storage of sterilised instruments
Instruments sterilised in a bench top steam steriliser should be used as soon
as possible after being autoclaved. They may be stored in a sterilised
container while awaiting use. Some instruments need to be sterilised
between uses to prevent cross infection, but can be used clean at point of
use. Do not immerse instruments in a chemical disinfectant whilst awaiting
use.
B 5.5.9
Use of sterilised instruments42
After sterilisation the steam condenses and the instruments will be wet unless
the steriliser has an effective drying stage. Once the door of the steriliser is
opened the load will quickly become contaminated with airborne particles.
Devices that must be sterile when used e.g. for minor surgery and
dentistry. Once sterilised these devices should be used immediately. If this is
not possible the instruments may be separated into two cycles, or used within
3 hours of sterilisation. If they are not used immediately they should be dried
in the steriliser using a post-sterilisation drying cycle and covered with a sterile
towel/lid.
Devices that must be sterilised between uses, but clean when used (e.g.
speculae for normal vaginal examination). Once sterilised the instruments
may be stored in a clean, dry environment. Alternatively, devices once
sterilised and dry can be placed in pouches (e.g. Steri-pouches) to protect
them from contamination.
Sterile devices that are transported outside the clinic e.g. dental or
podiatry instruments used for treatment in the home. Must be carried in a
sterilised container or pouch to protect them from contamination. Ideally they
should be in individualised sets for each treatment.
Pouches (e.g. Steri-pouches) must only be used in a vacuum steam steriliser.
If pouches are used in a steriliser they must be thoroughly dry before opening
the door of the steriliser, because micro-organisms can penetrate damp
packaging.

B 5.5.10
Reservoir and chamber management41,42
Poor management of the reservoir and chamber can result in contaminated
steam being used. Full guidance is available in HTM 2031.
•
Empty, clean and dry the reservoir and chamber when not in use
•
Refill the reservoir (not topped-up) with sterile water for irrigation prior
to use
•
Clean the chamber with sterile water for irrigation before and after use
and left dry.
B 5.5.11
Traceability and record keeping42,146
It is important to have good quality record keeping systems in place to provide
evidence that each steriliser functions correctly and achieves sterilising
conditions. The logbook will provide a complete history of the steriliser. MDA
DB2002 (06) gives full details of the records that need to be kept. Records of
every cycle should be kept to demonstrate that the load has been effectively
sterilised. If control indicator strips or automatic printouts are used they must
also be recorded in the logbook.
Tracking and traceability systems that are suitable for the level of procedures
being undertaken must be in place, e.g. for invasive procedures details of the
specific cycles on washer-disinfector and sterilisers must be kept in patients’
notes.
B
5.5.12
Key points for sterilisation of instruments in the
community
•
Ensure that decontamination processes comply with the National
Decontamination Strategy
•
Arrange the workflow to keep dirty and sterilised instruments
separated.
•
Clean and dry instruments using a washer-disinfector prior to
sterilising.
•
Wear gloves, apron and eye protection (if required) when cleaning
instruments.
•
Transportable steam steriliser must be suitable for processing the
intended loads.
•
Users of sterilisers must be trained in their use and maintenance
•
Sterilisers must be maintained and tested quarterly and annually by a
qualified engineer.
•
User must carry out and record the daily and weekly checks as per
Table 5.
•
Report any fault immediately to the engineer.
•
Empty reservoirs at the end of the session/day
•
Replenish reservoirs with sterile water for irrigation prior to next
session.
•
At the end of the session/day, rinse internal surfaces with sterile water
for irrigation
•
Load instruments into the steriliser so that they are not touching.
•
Instruments must be sterilised for:
3 minutes
at 1340 – 1370 C
10 minutes
at 1260 – 1290 C
15 minutes
at 1210 – 1240 C

•
Instruments that are
wrapped or in pouches must only be sterilised in
a vacuum steriliser.
• Instruments
with
narrow lumens, or porous loads must only
be
sterilised in vacuum steriliser.
•
Do not soak instruments in disinfectants before or after sterilising.
•
If a vacuum steriliser is not available send instruments with lumens
and porous loads to CSSD or use disposables and process other
instruments unwrapped
•
Use instruments as soon as possible after being sterilised.
•
Store instruments in a clean, dry, dust free place if they are to be used
for clean non-sterile procedures.
•
Retain records for at least 11 years
B 5.6 Decontamination of Health Care Equipment Prior to Repair,
Service or Investigation50,51
No equipment that has been contaminated with blood and other body fluids,
or exposed to patients with a known infectious disease, should be sent to
third parties without being correctly decontaminated first. If in doubt, contact
the third party in advance. After decontamination and before dispatching the
item it should be labelled with a declaration of its decontamination status that
states the method of decontamination used, or reasons why this was not
possible. (MHRA, 2003)50.
Some equipment cannot be effectively decontaminated without being
dismantled by an engineer. In addition decontamination may sometimes
remove evidence of a fault or hinder an investigation. In these situations the
manufacturer, repair organisation or investigating body should be contacted
for advice regarding packaging and transportation. A “Biohazard” label
should be attached to the item, the certificate completed accordingly and staff
advised on protective measures required.
B 5.7 Home Loans Equipment51 Equipment that has been used in clinical care must be safe to handle before
returning to the home loans store and the principles outlined above apply
equally to equipment that is loaned for clinical or social care.
•
Empty suction machines and rinse suction bottles with warm water
and detergent, rinse and dry
•
If soiled, clean other items with warm water and detergent and dry
•
If items cannot be cleaned prior to collection/delivery inform the Home
Loan Stores Manager so that precautions can be taken.
•
When selecting beds, chairs etc for clients who have incontinence
problems or leaking wounds select items with waterproof covering that
is easily be cleaned
•
Upholstered items that are superficially contaminated may be cleaned
by wiping with detergent and water or by a steam clean.
•
Upholstered items that have been grossly contaminated may need to
be re-upholstered or destroyed
•
Home loans staff involved in collecting used items should wear
disposable gloves when handling potentially soiled items.
•
Remove the gloves once item is loaded and clean hands using alcohol
wipes/gel or soap and water.

B 5.8 Endoscopes 29,32,52
•
Endoscopic procedures carry a significant risk of infection and it is
therefore recommended that endoscopy be not undertaken in
community settings without first carrying out a comprehensive risk
assessment. To reduce the risk of infection to a minimum requires
excellent decontamination facilities including cleaning, disinfection
and/or sterilisation procedures.
•
Should it be considered necessary to introduce a community
endoscopy service reference must be made the MDA DB2002(05)
Decontamination of Endoscopes52 and advice sought from the relevant
hospital and community infection control teams and managers of
sterile services. Specific procedures must then be developed which
are relevant to the location, the type of endoscopy to be undertaken
and the risk of infection.
•
Single-use devices are recommended wherever possible and any re-
usable items must be traceable in accordance with Health Service
Circular HSC2000/03234.
•
Where disinfectants are used a COSHH assessment29 must be
undertaken and controls put in place to ensure that the patients, staff
and visitors exposure to the chemical does not exceed the maximum
exposure limit (MEL).
•
Glutaraldehyde is not recommended in community settings. If it
should never be used if other appropriate disinfectants are available.
If its use is unavoidable a number of controls must be in place to limit
exposure to fumes and contact with the chemical, to manage spillage
and to monitor staff health.

B 6.0 Laundry 4, 53, 145
Aim:
•
The eradication or reduction in the number of organisms on
linen/clothing
•
Minimise the use of linen where no laundry service is available
•
Protection of staff and prevention of cross infection
B 6.1 Handling used linen
Linen may be contaminated with bodily fluids and debris. Inspect the linen
when removed. If fouled with body fluids, linen should always be removed
using gloves and disposable aprons. Where solid matter is present, this must
be removed using disposable paper and disposed of in either a WC or slop-
hopper.
Foul/infected linen should not be handled any more than is absolutely
necessary. Do not sluice by hand as this may spray micro-organisms onto
surfaces, uniforms and skin. Soiled or fouled articles should be washed on
the hottest cycle the fabric will allow. Those items that are not washable,
should be dry cleaned or, if necessary, destroyed.
Bed linen should not be shaken and it must be removed with care, avoiding
the creation of dust and dissemination of skin scales.
B 6.2 Colour-coding used linen
In clinical settings, a laundry service may be available and used and soiled
linen should be placed into the appropriate colour laundry bag. If a laundry
service is not available, use paper products where possible. In residential
care settings it can be helpful to introduce a colour-coding system. Assess
the condition of used linen and clothing to decide which category it falls into.

B 6.3 Laundry practice in residential care settings and client’s home
•
Always wash hands after handling used linen
•
Gloves must be available for handling fouled linen
•
Staff who undertake laundering must receive training
•
Laundry must not be sorted on the floor.
•
Washing machines and driers should not be sited in kitchens. This
may be unavoidable in client’s homes, so avoid doing laundry at the
same time as the cooking and ensure hands are washed.
•
Foul or infected laundry should be laundered after all the other routine
laundry has been done, using the hottest wash available for that fabric.
•
Used linen and fouled/infected linen should not be laundered together.
•
The washing machine must not be over loaded to ensure that the
machine functions adequately.
•
Laundry baskets should be cleaned with detergent and water after
containing soiled or fouled linen, or at least weekly.
•
Kitchen items and mop heads must be washed separately.
•
Use separate cleaning equipment for the laundry area.
•
Disinfect washing machines weekly by running a hot programme
without a load.
•
Prevent contamination of clean linen
B 6.4 Laundry facilities in residential care settings
A separate laundry facility, which is used solely for that purpose is
recommended for all residential care settings. However, it is recognised that
this is not always available in the client’s own home.
In a clinical environment, a full written risk assessment must be performed of
all laundering facilities. The person in charge should regularly review the risk
assessment.
B 6.4.1 Wash hand basin
•
Lever action mixer taps are recommended
•
Liquid soap and paper towels must be available
•
A foot-pedal operated bin for paper towels should be provided
If hand washing delicate materials or other personal items is undertaken, a
designated sink or bowl, which is separate from the wash hand basin, must
be used.
B 6.4.2
Washing Machines
An industrial washing machine with a sluice cycle is recommended. Machines
must be regularly maintained and records retained

B 6.4.3
Drying facilities
Tumble driers are recommended.
B 6.4.4
Design of the laundry
•
The floor, walls, splash-backs, draining boards etc of the laundry must
be easily washed with no cracks visible in the surface. It is advisable
that floors are non-slip.
•
The design of the laundry must facilitate the creation of dirty and clean
areas i.e. dirty linen can be bought into one area moved through the
laundry as it is processed and come out as clean laundry without
crossing over the route for used laundry.
•
Any laundry bins should be fully washable and be well maintained.
B 6.5 During outbreaks in residential care settings
•
Hand wash at appropriate times
•
Use red alginate linen bags for fouled/infected linen to minimise
contact. Alginate bags can be placed directly into a washing machine
and will dissolve in contact with the water. Some residue may remain.
•
If alginate bags are not available use red plastic bags. Empty the
contents into the washing machine without handling and discard the
bag.
•
Minimise the number of people visiting the laundry
•
Keep the laundry room and equipment especially clean
•
Ensure contaminated linen is kept away from clean linen
B 6.6 Ozone washing machine (OTEX)
Otex Validated Ozone Disinfection is a new laundry system that injects and
dissolves ozone into the wash water throughout the wash cycle. The
manufacturers claim that the product kills micro-organisms even at low
temperatures. The Health Protection Agency’s Rapid Review Panel
undertook a review of the product and recommended that, at the time, the
product was insufficiently validated and more research was needed into its
efficacy.

B 7.0 Disposal of waste54,55,56, 145, 153
B 7.1 Responsibilities
The Environmental Protection Act 199055 applies to waste disposal. This
legislation refers the
Duty of Care, which places a duty of care on all persons
producing waste to safely manage the handling and disposal of the waste in
the correct and proper manner. The following information will help meet the
duty of care. Healthcare waste must be managed in accordance with current
legislation and national guidelines.
Healthcare organisations should have a waste policy in place, which is owned
by the senior managers and supported by training and audit. Under Section
16 of the Care Homes Regulations, care homes are also obliged to have
suitable arrangements in place for the disposal of waste.
This guideline does not contain all the relevant information, so it is advisable
for managers to refer to the original source documents in developing local
policy and discuss local policy with their waste manager or Contractor.

Examples of Non-Hazardous Waste:
Infectious waste
Offensive/hygiene waste
Medicines
Domestic waste
Amalgam
Food waste

Infectious waste has two categories for the purposes of transport legislation:
Category A: An infectious substance which is transported in a form that, when
exposure to it occurs, is capable of causing permanent disability, life-
threatening or fatal disease in humans or animals. Highly infectious waste
includes waste arising from exotic infectious diseases and laboratory cultures;
Category B: An infectious substance which does not meet the criteria for
inclusion in Category A. This constitutes most infectious waste produced in
healthcare.
Offensive/hygiene waste: is non-infectious waste arising from healthcare,
which does not require specialist treatment but may cause offence to those
coming into contact with it; i.e. human hygiene waste, incontinence products,
sanitary waste, nappies, plaster casts etc.
Medicinal waste has two categories:
1. Cytotoxic and cytostatic;
2. Medicines others than cytotoxic and cytostatic

Staff must assess waste as it is produced to identify its infectious, chemical
and medicinal properties and segregate appropriately for disposal. National
guidelines produce useful flowcharts. See

B 7.3 Storage of clinical waste
•
Pedal bins must be available where clinical waste and contaminated
household waste are generated.
•
Bins must be lined with the appropriate colour liner.
•
Remove clinical waste bags when they are three-quarters full or at the
end of the day, as appropriate.
•
Securely tie bags as per local arrangements using tape, clips or tying
in a swan-neck before removing them from the bin
•
Label clinical waste bags and sharps boxes with the address of where
the waste was produced. This may be using labelled tape or clips, or
simply by writing the address or Post Code in permanent marker pen
onto the bag prior to use.
•
Hold bags by the neck and do not throw them.
•
Clinical waste should be stored in a designated waste collection point
or wheeled bin away from residential and food preparation areas.
Ideally in a lockable fixed or wheeled external bin awaiting collection.
•
Bins provided for clinical waste must be kept in a secure locked
location, that is well-lit, ventilated and marked with warning signs.
•
Waste must be collected by a registered carrier at regular intervals
e.g. weekly
•
Waste contractors are under no obligation to remove waste if it
does not adhere to the duty of care, e.g. packaged and labelled
correctly.
B 7.4 Clinical waste and cytotoxic waste from patients’ homes54
Patients and informal carers (partner/spouse, relatives or friends) also need to
understand waste disposal procedures, if there is any possibility that they
might have to deal with any of the types of clinical waste mentioned here.
B 7.4.1
Infectious waste (dialysis, wounds, diarrhoea etc.)
Community healthcare workers must assess waste for hazardous properties,
especially “infectious.” This is based on professional assessment, clinical
signs and symptoms, prior knowledge of the patient. Wounds should be
assessed as infectious if they have signs of infection or are being treated with
antibiotics. Another examples are dialysis waste or infectious diarrhoea of
patient’s receiving healthcare at home. Waste products must be disposed of
using orange sacks/containers and waste collection arranged.
This collection may be via the local NHS Trust or Local Authority as per local
arrangements.
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 44 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 7.4.2 Non-infectious waste (dressings, incontinence pads etc)
Where the waste products of healthcare are assessed as non-infectious; i.e.
non-infectious wound dressings, incontinence pads etc, the waste should be
discarded as “offensive/hygiene waste” in a yellow bag with black stripe.
Small volumes of those healthcare products which may also be used by
householders; i.e. plasters, pads, small dressings, stoma bags etc may go
into a black bag and discarded as household waste if the householder
agrees. Primary wrappers must be opaque, clear or black and must not be
yellow or orange as this indicates infectious waste.
B 7.4.3
Clinical sharps
Patients who use needles at home should be provided with a sharps
container. Used syringes, insulin pens and ampoules should also be
discarded in a sharps container.
Sharps containers are listed in Part 1XA of the
Drug Tariff and are available
on FP10. Follow local disposal procedures, e.g. return containers to the
prescribing surgery for collection prior to incineration when full to the line
indicated on the container. The practice (or PCT if it manages waste for the
practice) will need to apply to the Environment Agency for registration of
exemption of the Waste Management Licensing Regulations 1994 (as
amended). Some Local Authorities are able to collect sharps containers from
householders, but may levy a charge for this service.
Community healthcare workers giving injections in the home should use a UN
approved sharps container that is labelled. When carrying the container, the
aperture must be temporarily closed to prevent accidental spills. When it is in
a vehicle, it must be kept out of sight and not left unattended. When three-
quarters full the container must be locked and disposed of as per Table 8.
Patients who need to use needles and syringes on an out-patient basis, may
be provided with a sharps container by the hospital and should return the
container to the hospital for disposal.
B 7.4.4
Cytotoxic waste
Cytotoxic waste arising from home care must be placed into an appropriate
yellow container with purple stripe. Community healthcare workers involved
in the administration of cytotoxic drugs in the home should use the waste
disposal arrangements of their Trust. If patients self-administer the cytotoxic
drugs the container should be returned to the hospital or GP surgery as
agreed.

B 7.5 Management of clinical sharps 147
Clinical sharps include needles, scalpels, stitch cutters, glass ampoules, pen
injection devices, sharp instruments and broken glass. The safe handling and
disposal of sharps is paramount in reducing the risk of exposure to blood-
borne viruses and extreme care must always be taken when using and
disposing of sharps.
•
Avoid using sharps, including pen injecting devices when
administrating medication to patients, wherever possible (e.g. use a
needle-less system such as
Vacutainer for venepuncture or
Unistix for
finger pricking)
•
Clinical sharps should be single-use only
•
The re-sheathing of used needles is hazardous and must be avoided
where possible. If this is unavoidable, select an automatic re-
sheathing needle or use a one-handed technique.
•
The user of sharps must discard them directly into a sharps container
•
Sharps containers must comply with UN3291 and BS7320: 1990
•
Label sharps containers when assembling them
•
When carrying a sharps container, or whenever the container is left
unattended, use the temporary closure to prevent spillage or
tampering
•
Place sharps containers of a suitable size in each location where
sharps are handled, on a level surface
•
Secure containers using brackets attached to the wall or a trolley. Do
not place them on the floor, window sills or above shoulder height,
•
Assemble containers following manufacturer’s instructions
•
Carry them by the handle, do not hold them close to the body
•
Do not attempt to retrieve items from a sharps container
•
Do not attempt to press down upon sharps to make more room
•
Discard when three-quarters full or after 3 months. Lock the container
using the closure mechanism
•
Place damaged sharps containers inside a larger containers, lock and
label prior to disposal
•
If sharps are spilled from the container use a safe technique to retrieve
them, e.g. a dustpan and brush, and carefully place inside the
container
•
Never use single-patient use devices for more than one patient
•
Never put a sharps container inside a clinical waste bag
B 7.6 Household/domestic waste
•
Pedal-operated bins are recommended, though open bins are
adequate for paper towels.
•
Any waste that is not covered under the clinical waste groupings is
classed as household domestic waste, e.g. wastepaper, cans, bottles.
•
This waste must be disposed of through the normal household waste
stream i.e. black bin liners or dustbins collected by the Local Authority.
Where possible, recycling or re-using options should be considered.
•
Household waste and clinical waste must be kept separate at all times.
•
Reducing waste can save money and help to improve the environment
•
Ensure patients/clients or their informal carers are aware of the need
to deal with clinical waste appropriately.

2nd Edition (2007)
B 8.0 Single use medical devices3,57,58,59,60
Packaging of medical devices will indicate whether an item is for single use or
for single patient use.
Items labelled “single use only” (see symbol below) must be used only once.
The manufacturer will not guarantee that any form of reprocessing, (which
includes washing in soap and water) will not harm or change the safety of the
device.
If the manufacturer advises that it can be used more than once, e.g. “single
patient use”, the necessary information will be given on the packaging. It will
include details of whether it is for re-use only on one patient, the correct
method of cleaning between uses, and also, how long the item may be safely
used for.
Ignoring the advice printed on the packaging and re-using an item (device)
outside the guidelines given by the manufacturer has legal implications, which
basically mean that if anything untoward happens as a result of re-use, any
legal claim can be made against the user, and not the manufacturer.
Re-use and reprocessing of devices not intended for reuse may constitute
committing an offence under The Health and Safety at Work Act 1974,3 Part
One of the Consumer Protection Act 1987,58 The General Product Safety
Regulations 199459 or The Medical Devices Regulations 199460.
If the manufacturer’s instructions on single use, or single patient use are
ignored, the safety, performance and effectiveness of the device are
compromised and you will be exposing patients/clients and staff to
unnecessary risk.
Follow the instructions on the packaging and do not reuse.

B 9.0 Food
Hygiene61-66
B 9.1 Introduction
All foods are potentially hazardous if they are not handled correctly. Good
food handling practices are essential to minimise the risk of food poisoning.
This is especially important in residential care settings where food is being
prepared and served to large numbers, and where consumers are at
particular risk from food borne illnesses.
Managers and staff must be aware of legislation relevant to food. Hospitals
and residential care settings should appoint or have access to a qualified
catering manager. The main legislation is the Food Safety Act 199062 and its
related regulations.
The local Environmental Health Department can advise about rules and
regulations. Environmental Health Officers of the local authority in enforcing
these regulations are entitled to inspect catering facilities in residential care
homes.
A useful book to obtain for further information is ‘Industry Guide to Hygiene
Practice: Catering Guide61.
Food poisoning can cause serious illness and even death particularly in the
elderly. It is important that all people involved in preparing and serving food
are aware of how to reduce the risk of food poisoning.
B 9.2 Training
People who handle or prepare food need an appropriate level of training in
the principles of food handling depending upon whether they serve food, cook
food or manage a kitchen. Training requirements are summarised in
Table 9. Where clients cook food for themselves, staff must ensure that the individual
is supported in applying the principles of food hygiene until independence is
achieved.
Courses may be provided by local colleges and NHS Trusts, as well as the:
•
Royal Institute of Public Health and Hygiene (RIPHH),
•
Royal Society of Health (RSH),
•
Royal Environmental Health Institute of Scotland (REHIS),
•
Society of Food Hygiene Technology (SOFHT)
•
Chartered Institute of Environmental Health (CIEH).
Details of what may be included in Stage 1 and Stage 2 training are in
Table
10.
Level 1 formal training. An example of this is undergoing a course such as
a Basic Food Hygiene Course. This is typically a 6-hour course, which aims
to develop a level of understanding of the basic principles of food hygiene.
Level 2 and 3 formal training. These courses deal with food hygiene in
more detail and will cover management issues as well. Typically level 2
involves 12 to 24 hours of training and level 3 involves 24 to 40 hours.

Table 10
Informal (work-based) training
Stage 1 Essentials of Food Hygiene
• Keep yourself clean and wear clean clothing
• Always wash your hands thoroughly: before handling food, after using the toilet,
handling raw foods or waste, before starting work, after every break, after
blowing your nose
• Tell your supervisor, before commencing work, of any skin, nose, throat,
stomach or bowel trouble or infected wound. You are breaking the law if you do
not.
• Ensure cuts and sores are covered with a waterproof, high visibility dressing
such as a blue plaster
• Avoid unnecessary handling of food
• Do not smoke, eat or drink in a food room, and never cough or sneeze over
food
• If you see something wrong - tell your supervisor
• Do not prepare food too far in advance of service
• Keep perishable food either refrigerated or piping hot
• Keep the preparation of raw and cooked food strictly separate
• When reheating food ensure it is piping hot
• Clean as you go. Keep all equipment and surfaces clean
• Follow any food safety instructions either on food packaging or from your
supervisor
Stage 2 Hygiene Awareness Training (appropriate to the job)
• The business's policy - priority given to food hygiene
• "Germs" – potential to cause illness
• Personal health and hygiene – need for high standards, reporting illness, rules
on smoking
• Cross contamination - causes, prevention
• Food storage – protection, temperature control
• Waste disposal, cleaning and disinfection – materials, methods and storage
• "Foreign body" contamination
• Awareness of pests
B 9.3 Hazard analysis
The Food Safety (General Food Hygiene) Regulations 199564 make a specific
requirement of organisations to undertake a hazard analysis. This is a
systematic examination of how food is prepared and how food safety hazards
are controlled.
An Environmental Health Officer will periodically inspect kitchens in
residential care settings. They will expect to see evidence of hazard analysis
and any records that support it. They will also ask managers and the staff
questions about the hazard analysis and how you implement it.
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 50 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
The main stages of undertaking a hazard analysis are as follows:
•
Identify all the things in your food operation which might go wrong
(hazards) and result in food poisoning or cause injury, (e.g. the
presence of bacteria in raw meat, or foreign material such as glass or
plastic in food);
•
Decide the points in the food operation at which things can go wrong
(e.g. places where cross-contamination between raw foods and ready-
to-eat products may occur);
•
Decide which of these points are critical to making sure food is safe,
and therefore must be properly controlled (e.g. the cooking of raw
meat or the use of sanitised equipment);
•
Put in place procedures to stop things going wrong (controls), and
make sure that you/your staff always carry them out (e.g. cooking
meat for a set time and temperature which is known to kill all of the
bacteria right through to the middle of the joint or ensuring that
equipment has been cleaned and sanitized at proper and regular
intervals);
•
From time to time, you must examine your food business to see if
anything has changed which might need your control measures to
change (e.g. new menu dishes may have new hazards and need new
controls, or new equipment may require different thermostat settings).
It is helpful to involve key staff in developing a hazard analysis and all staff
need to know the part that they have to play in making it work.
B 9.4 Record keeping
Although in law you do not have to provide documents or record your policies,
procedures and monitoring records, it would be difficult to show how you are
meeting this requirement without records or documents. It would also be
difficult, if charged with a Food Safety Act offence, to use the defence of Due
Diligence to show that you have done everything possible to avoid committing
an offence. It is important to provide details of procedures and retain
monitoring records particularly at critical control points.
The recommended documents/ records that should be retained include:
•
Hazard analysis summary
• Training
records
•
Food temperatures records (e.g. cooking, cold storage, hot holding
temperatures)
• Refrigeration
temperatures
• Cleaning
schedules
• Delivery
monitoring
records
•
Stock rotation records
• Pest
control
records
•
Equipment maintenance schedule

Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 51 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 9.5 Infectious diseases in staff9,10
People are a common source of food poisoning organisms. Staff who are
suffering from sickness, diarrhoea or heavy colds should not be allowed to
work with food. Staff suffering from discharges from the ears, eyes, nose or
those who have septic skin conditions should not be allowed to work with food
either.
See A 1.4.
Staff should notify their manager before they start their shift if they are
suffering from such as condition. The manager must make sure the
appropriate action is taken, such as excluding someone from work altogether
or allocating them other non-food duties. They must be symptom-free for 48
hours before returning to work. If they are suffering from a known gastro-
intestinal infection
see C 31.0 for exclusion periods.
B 9.6 Hand hygiene22
Refer to
B 1.0 for more details. Hand washing should be carried out on
entering a kitchen and frequently throughout the working day. It should
always happen after handling foods or articles that are a source of food
poisoning bacteria. Such things include raw meat, raw vegetables, rubbish
bins, etc. Hands should also be washed after going to the toilet, taking a
break, coughing or sneezing in to hands etc.
Good hand washing requires running warm water, soap (preferably liquid
antibacterial) and a nailbrush if hands are particularly soiled. Nailbrushes
should be single-use. Hand washing should take about 30 seconds and staff
should pay attention to all parts of the hands, fingers and wrists. Hands
should be dried using clean drying materials. The best materials are disposal
paper towels.
Hand sanitisers can also be used to supplement hand washing. These
contain alcohol and dry quickly on the hands. They can be used where hands
are only lightly soiled.
B 9.7 Protective clothing
In large kitchens (e.g. hospitals and care homes) anybody entering the
kitchen should wear suitable over-clothing, which may include a clean white
coat and hat.
In smaller kitchens or the home setting, a clean plastic apron with sleeves
rolled up under short-sleeved clothes is adequate. Staff who leave the
kitchen to undertake other duties should remove their protective clothing
before leaving the kitchen.
No jewellery, perfume or make-up should be worn whilst working with food. A
plain wedding ring being the only exception.
B 9.8 High risk food63-66
B 9.8.1
Raw eggs
Advice from the Department of Health on raw or lightly cooked eggs is that: -
"Everyone should avoid eating raw eggs or uncooked dishes made from
them, and vulnerable groups such as the elderly, the sick, babies, toddlers
and pregnant women, should make sure any eggs they eat are thoroughly
cooked until the white and yolk are solid. However, for healthy people there
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 52 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
is very little risk from eating eggs which are cooked, whether boiled, fried,
scrambled or poached."
•
Once purchased, eggs should be stored in a refrigerator, below 8oC.
•
Caterers should continue to increase their use of pasteurised egg,
particularly for dishes that are not subject to further cooking prior to
consumption.
•
Food hygiene training programmes should pay particular attention to
the correct handling of eggs, and food containing eggs, and the
avoidance of cross contamination.
The Public Health Laboratory Service65 and Food Standards Agency66 have
advised that:
•
Eggs are kept away from other foods, while in shells or when cracked
•
Don’t splash egg onto other foods, surfaces or dishes
•
Wash and dry hands after touching, or working with, eggs
•
Clean surfaces, dishes, utensils etc thoroughly using warm soapy
water after contact with eggs
B 9.8.2
Pâté, soft-ripened cheeses and cook-chill foods
Listeriosis, a disease which has been associated with the consumption of
these foods, may be mild or more severe, causing septicaemia, meningitis,
encephalitis or, if a pregnant woman becomes infected, can harm the
developing baby. Elderly people, or those who have impaired immunity due
to disease or treatment, are particularly vulnerable to infection.
Particular care needs to be taken in developing diets for vulnerable people;
they should avoid soft-ripened cheeses and should re-heat cook-chill meals
and ready-to-eat chicken until they are piping hot. During the late 1980s
there was an outbreak of Listeriosis associated with pate, but the difficulties
with production of this product now seem to have been satisfactorily
addressed.
B 9.8.3
Unpasteurised milk
Only pasteurised milk and milk-based products, should be offered for
consumption by clients. Care should be taken with the delivery site to ensure
that milk containers (bottles or cartons) are protected and that birds or
rodents cannot break the seal and allow contamination to occur. If pests
have perforated the lid, the entire contents of the bottle must be discarded
because milk is such a good material for germs to multiply in.
B 9.8.4
Under-cooked or raw foods
Research has shown that meat, which is undercooked and still pink after
cooking, may cause infection. It is therefore important that all meat and
poultry is thoroughly cooked until the juices run clear before being served.
Piping hot meat is safest; this can only be checked using a probe
thermometer, with a minimum 750 C being reached during cooking.
Cooked food kept at room temperature and then re-heated is often implicated
in outbreaks of food-borne infection. Such practice is unsafe. Cold cooked
meats that are sliced some time prior to consumption may also be associated
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 53 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
with gastro-intestinal infections if poorly handled and/or left at room
temperature.
Shellfish, especially if eaten raw or undercooked, is recognised as being a
high-risk food. If served to vulnerable clients, particular care should be taken
to ensure proper preparation, cooking and handling of fresh, tinned and
frozen shellfish.
Salads, fruits and uncooked vegetables are a good source of vitamins,
minerals and fibre but they need careful preparation to ensure that the risk of
contamination is reduced. Because of possible contamination with pesticides
etc, where possible, fruit and vegetables should have the skin removed
providing this does not mean excessive manual handling. Leafy vegetables
such as lettuce, and fruit, should be washed thoroughly in running water. All
fruit and vegetables should be purchased from a reputable supplier.
B 9.9 Gifts of food
In residential care settings, visitors should be made aware of the dangers
posed by the high-risk foods discussed here, and they should inform the
person in charge of any gifts of food brought in. Gifts of food to clients should
be appropriately covered, then labelled with the name of the client and the
date of the gift. Such gifts should be appropriately stored, e.g. refrigerated
below 50 C if high risk, and consumed within 24 hours if possible.
B 9.10 Storage of food
Food must be stored at the correct temperature and in an appropriate place.
Most food poisoning germs will grow at temperatures between 5oC and 65oC,
and poor temperature control is an important cause of outbreaks of food
poisoning. Storage needs to take account of this.
•
The temperature of foods must be recorded using an accurate probe
thermometer, which is disinfected before and after each use e.g. using
probe disinfecting wipes or alcohol-impregnated wipes.
•
For all foods there should be careful attention to stock rotation so that
older stocks are used before new stocks. Food should be stored in
the appropriate place as soon as possible after delivery or preparation.
•
Dried food such as cereal must be stored in pest proof containers
above floor level.
•
Foods, which need to be kept cool, must be stored in a refrigerator.
These foods should be kept at a temperature of 5oC or below. The
refrigerator must have a thermometer and the temperature should be
checked daily and recorded. If the refrigerator temperature is above
50C this should be reported to the manager so that maintenance or
repairs can be carried out promptly. Care has to be taken to avoid
contamination of cooked foods with raw foods, especially raw meat
and poultry. These should be stored separately.
•
All food must be covered and labelled with the date before it is placed
in the refrigerator. Drugs or specimens must not be stored in the food
refrigerator.
•
Frozen foods should be clearly labelled with the date before placing in
the freezer. This is essential for efficient stock rotation.
G:\3-Policy\IC\Community\Part_B_Standard_precautions_v3.doc
Clinical Risk Services 31/07/2009 Issue 3 Review 30/07/2011 Page 54 of 65
HPA South West Community Infection Control Guidelines
2nd Edition (2007)
•
Hot foods must be kept hot at a temperature of 630C or higher.
•
Sandwiches should be prepared as close to the serving time as
possible (ideally one hour before they are served). They should be
stored covered in the refrigerator below 5 0 C before serving.
B 9.11
Food preparation
It is best practice, even in the home setting, to have separate areas and
equipment for the preparation of cooked and uncooked meat and poultry,
vegetables and salad. In the domestic setting be sure to explain what you are
doing and why to the patient/client or informal carer. They may feel your
precautions are unnecessary.
In hospitals and residential settings, equipment must be labelled or colour
coded so that cooked food does not become accidentally contaminated with
raw food. Germs on raw food (especially meat and poultry) may cause food
poisoning if they get onto food that is going to be eaten without further
cooking.
Some raw foods commonly contain food poisoning germs and they must be
cooked properly before serving. Meat and poultry must be thoroughly
defrosted before cooking to ensure that they reach the correct temperature
throughout. Defrosting should take place in a fridge rather than at room
temperature.
Raw shell eggs may contain salmonella, and they should not be used in
dishes where they are not cooked, such as homemade mayonnaise and
cheesecakes. Pasteurised egg should be used in these dishes, or
alternatively use recipes, which do not contain uncooked egg. Soft boiling or
poaching may not be adequate to kill all salmonella bacteria. The sick and
elderly are particularly at risk from salmonella.
Once prepared, foods should be kept at the correct temperature. Items that
require refrigeration should be placed in the refrigerator as soon as possible
after preparation. Hot foods should not be left standing at room temperature. If
they are not to be served immediately they should be stored in an oven or hot
plate. Cooked items, which are going to be stored cold (e.g. some joints of
meat) should be cooled as quickly as possible and then stored in a refrigerator.
Slicing food and spreading it over a large surface area can hasten cooling.
B 9.12
General hygiene
Deposits of food encourage the growth of micro-organisms and will attract
pests. Crockery, cutlery and other kitchen equipment should be cleaned
using a dishwasher where possible,
see B 5.0 and
Table 6. Cracked or
chipped crockery should be discarded. Food waste should be disposed of as
soon as possible
Kitchen cleaning must be carried out regularly to prevent a build-up of food
deposits behind, beneath and inside kitchen equipment. Spills should be
cleared up promptly. Thorough cleaning with a general purpose detergent
and drying with a clean disposable cloth will be adequate for most surfaces.
For food preparation surfaces a product that is a combined cleaner/disinfector
is recommended.

Pets67-70
Clients can enjoy contact with pets and have health benefits from this.
However there may be infection risks from pets especially if clients are
particularly vulnerable due to reduced immunity, age, illness or therapy.
Sensible precautions can reduce the risk to an acceptable level even in the
home setting. However, in a client’s home you may be able to make only
comparatively small changes, or concentrate on such hygiene measures as
washing your hands and any work surfaces thoroughly.
•
In communal settings, a designated person should be responsible for
looking after the pet. There should be written cleaning schedules for
birdcages and aquariums.
•
Wash hands after contact with pets.
•
Reptiles such as lizards, iguanas etc are very likely to be carriers of
exotic strains of salmonella that can be a health risk to young children.
Children under five should not have contact with such reptiles or the
environment in which the reptiles live or exercise.
•
After animal scratches or bites, clean the area thoroughly by washing
with soap under a running tap. Record the injury in the accident book.
Seek medical advice for bites, which break the skin and for any bites
or scratches which do not heal quickly or which appear infected.
•
If pets appear unwell seek veterinary advice. Ensure pets receive
regular veterinary care, vaccinations etc, where appropriate.
•
Pet feeding areas should be kept clean. Pets should have their own
feeding dishes, which should be washed separately from dishes and
utensils used by people.
•
Keep pets out of the kitchen and away from all surfaces where food is
prepared or consumed.
•
Keep opened pet food containers away from food for human
consumption
•
Food not consumed within 20 minutes should be removed or covered
to prevent attracting pests
•
Bedding should also be cleaned regularly and insecticides used as
necessary to control fleas; advice should be sought from the vet if
problems occur.
B 10.1
Litter box care
•
Pregnant women should avoid cleaning out the litter box
•
Always wear gloves and a protective apron when cleaning the litter
box.
•
Always wash hands after cleaning the litter box.
•
Fit a disposable liner to the box for easy cleaning.
•
Use a leak-proof litter box
•
Change the litter daily if soiled.

•
Seal litter in a plastic bag and dispose of with household waste
•
The litter box should not be sited near food preparation, storage or
eating areas.
•
Do not use the kitchen sink or hand washbasin for cleaning litter
boxes. Wash well using water and detergent, then fill with boiling
water and leave to stand for at least 5 minutes to kill toxoplasma eggs
and other micro-organisms. Finally leave to dry or dry with a
disposable cloth or paper towel.
• Certain animals are more likely to carry diseases that may spread to
humans:
o Stray
animals
o Sick
animals/birds
o Wild
animals/birds
o Animals with diarrhoea
o Exotic
animals
o Cage
birds
o Tropical
fish
o Domestic pets who hunt and eat rodents or birds
o Reptiles (iguanas, lizards etc) carry exotic salmonella species that
may be harmful to children under five or other vulnerable adults
Good general hygiene and hand washing are essential for risk reduction. By
ensuring that all the above advice is followed, the physical and psychological
benefits of having pets should improve the quality of life of the clients.

B 11.0 Visits to farms, zoos and other animal centres by children71
A number of infections can be acquired during visits to farms and similar
centres. These infections can include
Escherichia coli 0157, campylobacter,
salmonella, cryptosporidiosis etc. They are usually acquired by contact with
animals, their excreta or contaminated environment. Children under the age
of five years, or those who cannot manage their own hygiene needs are
particularly at risk.
A range of simple precautions can help to prevent infection. These include:
•
Check the farm is well managed and that the grounds and public areas
are as clean as possible. Note that manure, slurry and sick animals
pose a particular risk of infection and animals must be prohibited from
any picnic area
•
Check that the farm has washing facilities that are adequate and
accessible for the age and size of the children, with running water,
liquid soap and disposable paper towels or hot air dryers. Any
drinking water taps should be provided away from animals and toilets
•
Do not allow children to eat or drink anything, including crisps, sweets,
chewing gum etc, while touring the farm. They should also avoid
putting their fingers, pens or crayons in their mouths because of the
risk of infection
•
If children are in contact with, or help to feed, farm animals they must
be warned not to kiss animals, put their faces against the animal or
taste the animal feed
•
Everyone must wash and dry their hands after contact with animals
and also before eating or drinking
•
Meal-breaks or snacks should be taken well away from areas where
animals are kept, and pupils warned not to eat anything which may
have fallen to the ground
•
Any fruit or vegetables produced on the farm should be thoroughly
washed in drinking water before consumption
•
Children should not consume unpasteurised produce e.g. cheese or
milk
•
Hands must be washed before departure
•
Ensure that footwear is as free from faecal matter as possible
•
Pregnant women should remember that there is a particular risk of
transmission of infection during the lambing season.

B 12.0
Deaths of clients in the community
If the death occurred from a serious infectious condition that may have public
health implications, the clinician should inform the Health Protection Unit at
the earliest opportunity. Even anticipated deaths may give rise to enquiries,
and it is easier for the Health Protection Team to deal with these if they have
already received information.
B 12.1
Handling bodies11,72
It is important to consider the cultural elements concerning death and
preparation of bodies. Refer to any local policies or discuss this with the
client, family or informal carers even before death of possible. Inappropriate
handling may be greatly offensive.
Most bodies pose little risk of infection but sensible precautions will reduce
the risks even further. Disposable gloves and apron should be worn when
washing and preparing the body.
Clean dressings should be applied to any wounds or leakage sites and
secured with tape or a loose bandage to prevent any further leakage from the
site. The use of pins should be avoided since they present a potential hazard
to others.
It is important to contact the undertaker as soon as the death has been
certified, because the body needs to be moved to a cool environment as soon
as possible. Decomposition occurs rapidly, particularly in hot weather or an
overheated room, and may create a bacterial hazard and be unpleasant for
those handling the body.
If it is anticipated that there may be a delay in certifying the death for some
hours, it could be helpful to forewarn the undertaker so that plans can be
made to collect the body later. Cool the room where the body lies, by turning
off radiators and opening a window.
Dressings, drainage tubes etc should be removed before the body is
transferred to the undertaker
unless a Coroner’s post-mortem is likely.
Inform the undertaker if the body has a pacemaker fitted and if there is a
known, or suspected, infection hazard.
In the event of a Coroner’s post-mortem, any tubes must be plugged and
covered with a dressing pad and secured to the body with tape or bandage.

B 12.2
Last Offices for infected people6,11,72,73
Following the death of an individual with an infectious disease, the
precautions carried out prior to death must be continued after death since the
body may remain infectious. However, any cultural traditions must be
respected, having been identified in the assessment on arrival.
•
When laying out a body, wear disposable gloves and apron
•
If the infectious disease presents a serious infection hazard to others
(e.g. the diseases listed below) the body should be placed in a shroud
(or own clothes) and then into a plastic body bag, which should be
carefully secured.
• Typhoid
fever
• Paratyphoid
fever
• Acquired Immune Deficiency Syndrome (AIDS)
• Tuberculosis
• Transmissible spongiform encephalopathies e.g. Creutzfeldt Jakob
Disease
The identity labels and Notification of Death labels should be attached so that
they can be read through the body bag. A “danger of infection” label and a
Notification of Death label should be attached discreetly to the outside of the
bag. No label should state the diagnosis, which is confidential information.
The undertaker must be informed of the danger of infection, but without
disclosure of the diagnosis. Once the body is in the body bag, those handling
the bag no longer require the protective clothing.
Relatives and friends who wish to view the body should do so as soon as
possible after death. A member of staff wearing gloves and an apron can
open the bag.
It must be understood that there are provisions under the Public Health
(Control of Disease) Act 198473 to prevent contact with the body of a person
dying with a notifiable infectious disease. Relatives should be informed of
any risk of infection, though in most cases the risk is small and no greater
than when the deceased was alive.
The embalming of bodies infected with hepatitis B and C, HIV or CJD, is not
recommended.

Sharps and inoculation injuries and bites8,11,12, 13,14, 153
NB
Follow your organisation’s inoculation injury policy.
B 13.1
Risk assessment
B 13.1.1
Sharps include:
Needles, scalpel blades, stitch cutters, cannulae etc used in clinical care.
These may become contaminated with blood or high-risk body fluids during
use and there is a risk of accidental injury if not handled correctly.
B 13.1.2
High-risk inoculation injuries include:
•
Inoculation with an instrument such as a needle or scalpel blade,
which has been contaminated with blood, or one of the "high-risk"
body fluids listed below.
•
Contamination of mucous membranes (eye or mouth) or breaks in the
skin with blood, or another "high-risk" body fluid listed below.
•
A human bite, if the skin is broken
B 13.1.3
High-risk body fluids include:
Blood and blood products
Semen and vaginal secretions
Peritoneal fluid
Pericardial fluid
Synovial
fluid
Pleural
fluid
Amniotic
fluid
Breast
milk
Unfixed (and donated) organs and tissues
In relation to blood-borne infections, urine, faeces, vomit, sweat, tears, skin,
sputum are not considered to be high risk, unless they are bloodstained.
The risk of transmission of a blood-borne virus is associated with
inoculation of an
infectious dose of
infected body fluid into a
susceptible recipient.
A simple injury, which does not break the skin, or does not involve the
inoculation of body fluid, is unlikely to lead to the transmission of infection.
The infecting dose may be as low as a visible drop of blood. However other
individual factors may affect the risk of transmission.
Human bites very often become infected due to the large amount of bacteria
present in saliva, therefore check the wound daily for any signs of bacterial
infection and inform GP if present.

B 13.4
Post-exposure Prophylaxis for healthcare and public
sector workers8,11,12,14, 153
B 13.4.1
HIV
The Department of Health has issued guidelines on HIV Post-exposure
Prophylaxis (PEP) for health care workers. Although HIV PEP is
recommended for health care workers, the risk of transmission is very small
and requires the inoculation of a significant volume of infected body fluid. The
side effects of the treatment may also outweigh any potential benefit.
Following incidents where the source of the injury is thought to be high risk for
HIV infection, the injured party should go immediately to Accident and
Emergency to be assessed. The decision to administer PEP will be taken by
the consultant on call for PEP e.g. the medical microbiologist, haematologist,
virologist or occupational health physician at the local District General
Hospital.
If recommended, a course of PEP must be started as soon as possible after
the incident. Ideally this would be within one hour if there were a high risk of
exposure to HIV. However, PEP may be commenced up to 2 weeks after the
injury if circumstances change, for example if the source of the injury is
subsequently found to be HIV positive. The PEP specialist should advise
pregnant women, who may have been exposed to HIV, regarding the risks
and benefits of HIV PEP.
B 13.4.2
Hepatitis B
If the source of the injury is a known, or suspected to be, hepatitis B positive,
Occupational Health or the GP should consider giving hepatitis B vaccine
and/or immunoglobulin to the recipient of the injury. This should be
administered ideally within 48 hours of the injury, though it can be given up to
7 days after the incident if necessary.
B 13.4.3
Hepatitis C
Where possible an attempt should be made to assess the HCV status of the
source. An initial blood sample should be taken from the injured person and
sent to the laboratory to be stored. If the source is found to be positive, the
injured party should also be investigated for subsequent sero-conversion and
appropriate referral made as per
Part F, Appendix One. There is currently no
vaccine available for hepatitis C.
Following an incident a review of the event should be undertaken in order to
identify if the injury could be avoided in future.
B 13.5
Post exposure prophylaxis for the general public8,12
Members of the public may be accidentally exposed to blood via inoculation
or contamination of the eye, mouth or fresh cuts, or as a result of rape,
condom breakage or sharing drug-injecting equipment. As a first aid measure
contaminated skin should be washed with soap and water, or mucous
membrane flushed with fresh water or saline and medical advice sought. The
medical practitioner should carry out an individual risk assessment of the
circumstances of exposure.

HPA South West Community Infection Control Guidelines
2nd Edition (2007)
B 13.5.1
HIV
The risk of transmission of HIV as a result of incidents in the community is
small. It is also unlikely that Post Exposure Prophylaxis for HIV could be
administered within 1 hour of exposure. Therefore for a number of reasons
PEP may not be appropriate for members of the general public. If the doctor
considers the individual to be at high risk of HIV infection they should seek
urgent advice from a physician experienced in the treatment of HIV and the
use of PEP.
B 13.5.2
Hepatitis B
Blood-exposures if possible an attempt should be made to assess the HBV
status of the source. Following a risk assessment, it may be decided to
immunise the injured party using an accelerated course of hepatitis B
vaccine, if they are not already immunised (see
Part F, Appendix One).
Sexual partners of someone who has developed acute hepatitis B infection
should be offered post exposure prophylaxis as per
Part F, Appendix One.
Babies born to mothers who are hepatitis B carriers, or who had acute
hepatitis B infection during pregnancy:
•
Mother HBsAg positive
Baby should receive an accelerated
course of hepatitis B vaccine
•
Mother HBeAg positive, or where e-marker is undetermined.
Baby should receive hepatitis B immuno-globulin and start a course of
vaccine, given at a contra-lateral site at the same time.
B 13.5.3
Hepatitis C
If possible an attempt should be made to assess the HCV status of the
source. If positive, the injured party should also be investigated for
subsequent sero-conversion and appropriate referral made as per
Part F Appendix One. There is currently no vaccine available for hepatitis C.
