Viton

In common with many other manufacturers' vehicles, some components installed to the Jaguar range have 'O' rings, seals or
gaskets which contain a material known as 'Viton'.

Viton is a fluoroelastomer, that is a synthetic rubber type which contains Fluorine. It is commonly used for 'O' rings, gaskets
and seals of all types. Although Viton is the most well known fluoroelastomer, there are others, including Fluorel and
Tecmoflon.

When used under design conditions fluoroelastomers are perfectly safe. If, however, they are exposed to temperatures in
excess of 400º C, the material will not burn, but will decompose, and one of the products formed is hydrofluoric acid.
This acid is extremely corrosive and may be absorbed directly, through contact, into the body.

'O' rings, seals or gaskets which have been exposed to very high temperatures will appear charred or as a black sticky
substance.
DO NOT, under any circumstances touch them or the attached components.

Enquiries should be made to determine whether Viton or any other fluoroelastomer has been used in the affected 'O' ring, seal
or gasket. If they are of natural rubber or nitrile there is no hazard. If in doubt, be cautious and assume that the material may
be Viton or any fluoroelastomer.

If Viton or any other fluoroelastomers have been used, the affected area should be decontaminated before the commencement
of work.

Disposable heavy duty plastic gloves should be worn at all times, and the affected area washed down using wire wool and a
limewater (calcium hydroxide) solution to neutralize the acid before disposing of the decomposed Viton residue and final
cleaning of the area. After use, the plastic gloves should be discarded carefully and safely.

Welding

See also Fire, Electric Shock, Gas Cylinders.

Welding processes include Resistance Welding (Spot Welding), Arc Welding and Gas Welding (and cutting).
Resistance Welding (Spot Welding)
This process may cause particles of molten metal to be emitted at a high velocity, and the eyes and skin must be protected.
Arc Welding
This process emits a high level of ultraviolet radiation which may cause arc-eye and skin burns to the operator and to other
persons nearby. Gas-shielded welding processes are particularly hazardous in this respect. Personal protection must be worn,
and screens used to shield other people.
CONTACT LENS WEARERS ARE ADVISED TO REVERT TO ORDINARY SPECTACLES WHEN ARC WELDING as the arc spectrum is
believed to emit microwaves which dry out the fluid between the lens and the eye. This may result in blindness when the lens
is removed from the eye.
Metal spatter will also occur, and appropriate eye and skin protection is necessary.

The heat of the welding arc will produce fumes and gases from the metals being welded, the rods and from any applied
coatings or contamination on the surfaces being worked on. These gases and fumes may be toxic and inhalation of these
should be avoided. The use of extraction ventilation to remove the fumes from the working area may be necessary particularly
in cases where the general ventilation is poor, or where considerable welding work is anticipated. In extreme cases or confined
spaces where adequate ventilation cannot be provided, air-fed respirators may be necessary.
Gas Welding (and Cutting)

Oxy-acetylene torches may be used for welding and cutting, and special care must be taken to prevent leakage of these gases,
with consequent risk of fire and explosion.
The process will produce metal spatter and eye and skin protection is necessary.

The flame is bright, and eye protection should be used, but the ultraviolet emission is much less than that from arc welding,
and lighter filters may be used.

The process itself produces few toxic fumes, but such fumes and gases may be produced from coatings on the work,
particularly during cutting away of damaged body parts, and inhalation of the fumes should be avoided.

In brazing, toxic fumes may be produced from the metals in the brazing rod, and a severe hazard may arise if brazing rods
containing cadmium are used. In this event particular care must be taken to avoid inhalation of fumes and expert advice may
be required.

SPECIAL PRECAUTIONS MUST BE TAKEN BEFORE ANY WELDING OR CUTTING TAKES PLACE ON VESSELS WHICH HAVE
CONTAINED COMBUSTIBLE MATERIALS, E.G. BOILING OR STEAMING OUT OF FUEL TANKS.

Warning Symbols on Vehicles

Decals showing warning symbols will be found on various vehicle components.

be replaced as soon as possible to make sure full SRS protection.


If the SRS components are to be replaced, the part number/bar code of the new unit must be recorded.

SRS component testing precautions

The SRS components are triggered using relatively low operating currents, always adhere to the following :


WARNING: Never use a multimeter or other general purpose equipment on SRS components. Use only approved JLR
diagnostic equipment to diagnose system faults.




WARNING: Do not use electrical test equipment on the SRS harness while it is connected to any of the SRS components,
it may cause accidental deployment and injury.
Handling and storage

Always observe the following precautions when handling SRS components:



Never drop an SRS component. The airbag diagnostic control unit is a particularly shock sensitive device and must be
handled with extreme care. Airbag modules and seat belt pre-tensioners could deploy if subjected to a strong shock.
Never wrap your arms around an airbag module. If a module has to be carried, hold it by the cover with the cover
uppermost and the base away from your body.
Never transport airbag modules or seat belt pre-tensioners in the passenger compartment of a vehicle. Always use the
luggage compartment of the vehicle for carrying airbag modules and seat belt pre-tensioner units.
Never attach anything to an airbag cover or any trim component covering an airbag module. Do not allow anything to
rest on top of an airbag module.
Always keep components cool, dry and free from contamination.
Never apply grease or cleaning solvents to seat belt pre-tensioner units, component failure could result.
Always store an airbag module with the deployment side uppermost. If it is stored deployment side down, accidental
deployment will propel the airbag module with sufficient force to cause serious injury.
Keep new airbag modules in their original packaging until just prior to installing. Place the old module in the empty
packaging for carriage.

Inspection and Verification

1. Verify the customer concern by carrying out a road test on a smooth road. If any vibrations are apparent, refer to
section 100-04 Noise, Vibration and Harshness.
2. Visually inspect for obvious signs of damage and system integrity.
