DO YOU KNOW HOW TO WORK SAFELY WITH PCBs?
PCBs and YOU |
CONTENTS
Department of the Environment
Do you dismantle or replace old electrical equipment, including
switchgear, transformers and capacitors?
This equipment may contain chemicals called PCBs which can harm
your health.
Do you know how to work safely with PCBs?
Is your health at risk?
Make sure you know what to do before you start work.
This leaflet provides an introduction to these questions. Further,
more detailed information is contained in the booklet How to
handle PCBs without harming yourself or the environment. You
should consult this before carrying out regular or substantial work.
Alternatively, specialist contractors can carry out the work.
Polychlorinated biphenyls (PCBs) can harm the environment and could
damage your health. Because of environmental concerns, an
international agreement in 1986 banned most uses. Agreement has been
reached to phase out remaining uses by the year 2000.
WHAT ARE PCBs?
PCBs are a family of substances which are good electrical insulators.
They are chemically stable, fire resistant and don't easily generate
a vapour. You may find them in mixtures referred to as askarels or
under a trade name. Examples of trade names of products which have
contained PCBs are at the end of this leaflet.
WHERE WILL I FIND PCBs?
PCBs were used as dielectric filler liquids in some types of
electrical equipment such as transformers, switchgear, capacitors and
in the starter units of fluorescent lights and fractional horsepower
motors. Some equipment is labelled as containing PCBs but if you come
across old equipment with no identifying label you should check with:
You should assume that any capacitor or transformer manufactured
before 1976 may contains PCBs unless you have information to the
contrary. It is also possible that there may be PCBs present in
capacitors and transformers manufactured between 1976-1986. Even if
the PCBs have been replaced by another liquid, significant amounts of
PCBs may still be present. PCBs may occur as contaminants in the oil
used in oil-filled electrical equipment. Always check with your
employer if you are in any doubt.
HOW CAN THEY ENTER MY BODY?
PCBs can enter your body in three ways:
by direct contact with the skin. PCBs pass easily through intact
skin, so this is likely to be the main way they get into your body;
by breathing in fumes, spray or droplets if PCB-containing equipment
is being cut or heated;
by swallowing PCBs if you eat, drink or smoke in the workplace.
HOW CAN THEY AFFECT MY HEALTH?
If you are repeatedly exposed to PCBs they can gradually build up in
your body. PCBs can cause a skin condition called chloracne, which
produces pustules, blackheads and cysts. In animals PCBs can cause
damage to the liver, reduce the ability to fight infection, as well
as other effects. Apart from chloracne, none of the range of effects
seen in animals has been seen in people working with PCBs, although
it is possible that they could occur if high exposures were to occur.
WHAT PRECAUTIONS SHOULD I TAKE?
All PCB-containing equipment needs to be checked regularly for signs
of PCB leakage. If substantial leakage occurs you should obtain the
assistance of a specialist contractor immediately.
You should not do any work where there is a possibility that you
may come into contact with PCBs, including dealing with spilt PCBs,
unless your employer has trained you and given you a method to follow.
Because PCBs can pass easily through your skin, you should wear
personal protective equipment if there is any possibility of contact
with PCBs. All cuts and abrasions need to be covered with dressings
before you put on your protective clothing. Your employer will tell
you the right type of protective clothing for your job, which may include:
an impervious boilersuit or overalls;
suitable gloves;
overshoes or wellingtons;
chemical resistant goggles or visor;
respirator.
However, no material is completely impervious to PCBs. The booklet How
to handle PCBs without harming yourself or the environment gives
details of those materials which give the best protection.
In some instances capacitors in fluorescent light fittings may leak
and need replacing. Here only very small quantities of fluid are
involved and it may not be necessary to obtain the assistance of a
specialist contactor. To do this you need to wear disposable gloves,
wipe down any spillage with paper or cloth wipes, and wash your hands
when you have finished the job.
If your protective clothing becomes contaminated with PCBs, do not
take it home to wash it, or send it to a laundry. See 'How do I
dispose of PCBs?' below.
Where PCBs may be present, do not eat, drink or smoke and wash
thoroughly before eating, drinking, smoking or using toilet
facilities. These measures are important to ensure that you do not
come into contact with PCBs.
HOW DO I DISPOSE OF PCBs?
PCBs, PCB waste (including protective clothing that has been
contaminated with PCBs) and equipment containing PCBs must only
be disposed of by specialist waste contracting firms which are
licensed by the Waste Regulation Authority. You must not dispose of
PCBs or PCB waste by pouring it into drains, onto land or by burning.
PCBs are normally destroyed in an incinerator authorised to burn
PCBs, although there are other ways of destroying PCBs. You can get
advice on how to dispose of very small amounts of PCBs (such as a few
capacitors from fluorescent lights) from your Waste Regulation
Authority. The National Association of Waste Disposal Contractors
(NAWDC) can provide a list of their members licensed to dispose of PCBs.
ARE THERE ANY RELEVANT LAWS?
Yes, there are several laws which apply to PCBs:
The Health and Safety at Work etc Act 1974 requires employers
to ensure so far as is reasonably practicable the health, safety and
welfare of all their employees at work. You are required to
co-operate with your employer, for example by using safety equipment
and working methods as instructed.
The Control of Substances Hazardous to Health Regulations 1994
(COSHH) place duties on your employer to:
ensure that your exposure to PCBs is either prevented, or if this is
not reasonably practicable, adequately controlled;
assess the risks to your health from PCBs and identify the measures
which are needed to protect your health;
ensure that control measures are adequate and that you use them;
monitor your exposure;
provide you with information on the risks of PCBs and the steps which
are necessary to protect your health.
You also have duties under COSHH to:
The Environmental Protection Act 1990 requires, amongst other
things, waste holders to exercise a duty of care when disposing of
certain materials. For further details see 'Where can I get more information?'
WHERE CAN I GET MORE INFORMATION?
Your local HSE office will provide more advice and information on
work involving PCBs. It is listed under Health and Safety Executive
in the local telephone directory. If you are worried that you may
have absorbed PCBs through working with them, you can obtain
confidential advice from the Employment Medical Advisory Service, who
can be contacted though your local HSE office. The booklet How to
handle PCBs without harming yourself or the environment (ISBN 0
7176 0789 5) can be obtained from HSE Books.
For information on the handling and disposal of PCBs see Waste
Management Paper No 6 - Polychlorinated biphenyls (DoE 1994,
available from HMSO) or contact your local Waste Regulation Authority
(listed in your local telephone directory) or the Department of the
Environment Enquiry Unit, 2 Marsham Street, London SWIP 3EB (Tel 0171
276 3000).
The National Association of Waste Disposal Contractors (NAWDC) will
be able to give you a list of contractors who can handle PCBs and PCB
waste. Their address is Mountbarrow House, 6-20 Elizabeth Street,
London, SWIW 9RB.
