2007 FORD FIESTA cylinder head gasket

100-00-12 General Information 100-00-12
DESCRIPTION AND OPERATION
Gross or prolonged skin contact with high boiling
point gas oils may also cause serious skin
disorders including skin cancer.
Kerosene (Paraffin)
Used also as heating fuel, solvent and cleaning
agent.
Flammable
- observe No Smoking policy.
Irritation of the mouth and throat may result from
swallowing. The main hazard from swallowing
arises if liquid aspiration into the lungs occurs.
Liquid contact dries the skin and can cause
irritation or dermatitis. Splashes in the eye may be
slightly irritating.
In normal circumstances the low volatility does not
give rise to harmful vapors. Exposure to mists and
vapors from kerosene at elevated temperature
should be avoided (mists may arise in dewaxing).
Avoid skin and eye contact and make sure there
is adequate ventilation.
Alternative Fuel
Highly flammable. Observe "NO SMOKING" signs.
Make sure there is adequate ventilation when
working on alternative fuelled vehicles. Great care
must be taken to avoid the serious consequences
of inhalation in the event of vapor build up in
confined spaces.
Inhalation in high concentrations may cause
dizziness, headache, nausea and loss of
co-ordination. Very high concentrations may result
in loss of consciousness.
Contact with liquefied petroleum gas (LPG) or
compressed natural gas (CNG) to the skin may
cause cold burns and frost bite.
Long sleeved cotton overalls, steel toe capped
safety boots and rubber neoprene gloves should
be worn during removal and installation of
LPGICNG fuel system components.
LPGICNG fuel leaks could cause a fire and be a
hazard to health that can lead to personal injury,
illness or even death.
If a leak is detected, under no circumstances
attempt to seal the leak by tightening the
unionlconnection until the fuel in the system or
component is depressurized. Once tightened the
system should be checked for integrity following
the specified procedures. If
the fuel tank is to be removed for service or repair
the fuel must be evacuated using dedicated
equipment and following the specified
procedures. (
Gas Cylinders
See also Fire.
Gases such as oxygen, acetylene, argon and
propane are normally stored in cylinders at
pressures of up to
138 bar (2000 psi) and great
care should be taken in handling these cylinders
to avoid mechanical damage to them or to the valve
gear attached. The contents of each cylinder
should be clearly identified by appropriate
markings.
Cylinders should be stored in well-ventilated
enclosures, and protected from ice and snow, or
direct sunlight. Fuel gases, for example acetylene
and propane, should not be stored in close
proximity to oxygen cylinders.
Care should be exercised to prevent leaks from
gas cylinders and lines, and to avoid sources of
ignition.
Only trained personnel should undertake work
involving gas cylinders.
Gases
See Gas Cylinders.
Gaskets (Fluoroelastomer)
See Viton.
General Workshop Tools and
Equipment
It is essential that all tools and equipment are
maintained in good condition and that the correct
safety equipment is used where required.
Never use tools or equipment for any purpose other
than that for which they were designed. Never
overload equipment such as hoists, jacks, axle and
chassis stands or
lifting slings. Damage caused by
overloading is not always immediately apparent
and may result in a fatal failure the next time that
the equipment is used.
