INFORMATION FUEL HANDLING PRECAUTIONS
The following information provides basic precautions
which must be observed if fuel is to be handled safely.
It also outlines the other areas of risk which must not
be ignored.
This information is issued for basic guidance only, and
in any case of doubt, appropriate enquiries should be
made of your local Fire Officer or Fire Department.
Fuel vapour is highly flammable and in confined
spaces is also very explosive and toxic and when
diluted with air becomes a readily ignitable mixture.
The vapour is heavier than air and will always fall to
the lowest level. It can readily be distributed
throughout a workshop by air current, consequently,
even a small spillage of fuel is very dangerous.
Always have a fire extinguisher containingFOAM CO
2
GAS,orPOWDERclose at hand when handling fuel,
or when dismantling fuel systems and in areas where
fuel containers are stored.
WARNING: lt is imperative that the battery
is not disconnected during fuel system
repairs as arcing at the battery terminal
could ignite fuel vapour in the atmosphere.
Always disconnect the vehicle battery BEFORE
carrying out work on the fuel system.
Whenever fuel is being handled, transferred or
stored, or when fuel systems are being dismantled
all forms of ignition must be extinguished or
removed, any leadlamps used must be flame proof
and kept clear of spillage.
No one should be permitted to repair components
associated with fuel without first having had fuel
system training.Hot fuel handling precautions
WARNING: Before commencing any
operation requiring fuel to be drained from
the fuel tank, the following procedure must
be adhered to:
1.Allow sufficient time for the fuel to cool, thus
avoiding contact with hot fuels.
2.Vent the system by removing the fuel filler cap in
a well ventilated area. Refit the filler cap until the
commencement of fuel drainage.
Fuel transfer
WARNING: Fuel must not be extracted or
drained from any vehicle while it is
standing over a pit.
The transfer of fuel from the vehicle fuel tank must be
carried out in a well ventilated area. An approved
transfer tank must be used according to the transfer
tank manufacturer’s instructions and local regulations,
including attention to grounding of tanks.
Fuel tank removal
AFUEL VAPOURwarning label must be attached to
the fuel tank upon removal from the vehicle.
Fuel tank repair
Under no circumstances should a repair to any tank
be attempted.

INFORMATION SYNTHETIC RUBBER
Many’0’ring seals, flexible pipes and other similar
items which appear to be natural rubber are made of
synthetic materials called Fluoroelastomers. Under
normal operating conditions this material is safe, and
does not present a health hazard. However, if the
material is damaged by fire or excessive heat, it can
break down and produce highly corrosive Hydrofluoric
acid which can cause serious burns on contact with
skin. Should the material be in a burnt or overheated
condition handle only with seamless industrial gloves.
Decontaminate and dispose of the gloves immediately
after use.
If skin contact does occur, remove any contaminated
clothing immediately and obtain medical assistance
without delay. In the meantime, wash the affected
area with copious amounts of cold water or limewater
for fifteen to sixty minutes.
RECOMMENDED SEALANTS
A number of branded products are recommended in
this manual for use during maintenance and repair
work.
These items include:
HYLOMAR GASKET AND JOINTING COMPOUND
and
HYLOSIL RTV SILICONE COMPOUND.
They should be available locally from garage
equipment suppliers. If there is any problem obtaining
supplies, contact the following company for advice
and the address of the nearest supplier.
MARSTON LUBRICANTS LTD.
Hylo House,
Cale Lane,
New Springs,
Wigan WN2 1JR
Tel 01942 824242USED ENGINE OIL
WARNING: Prolonged and repeated
contact with engine or motor oil will result
in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis.
Used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities should be provided.
Handling precautions
1.Avoid prolonged and repeated contact with oils,
particularly used engine oils.
2.Wear protective clothing, including impervious
gloves where applicable.
3.Do not put oily rags in pockets.
4.Avoid contaminating clothes, particularly
underwear, with oil.
5.Overalls must be cleaned regularly. Discard
unwashable clothing and oil impregnated
footwear.
6.First aid treatment must be obtained immediately
for open cuts and wounds.
7.Use barrier creams, before each work period, to
help the removal of oil from the skin.
8.Wash with soap and water to ensure all oil is
removed (skin cleansers and nail brushes will
help). Preparations containing lanolin replace the
natural skin oils which have been removed.
9.Do not use gasoline, kerosene, diesel fuel,
petrol, thinners or solvents for washing the skin.
10.If skin disorders develop, obtain medical advice.
11.Where practicable, degrease components prior
to handling.
12.Where there is a risk of eye contact, eye
protection should be worn, for example, goggles
or face shields; in addition an eye wash facility
should be provided.
Disposing of used oils
Environmental protection precaution
It is illegal to pour used oil onto the ground, down
sewers or drains, or into waterways.
Dispose of used oil through authorised waste disposal
contractors. If in doubt contact your Local Authority for
advice on disposal facilities.
