15.1.6 Fire Hazard Infonnath
Thermal decomposition or combustion may produce dense smoke and other dangerous fumes which in fire situations
form
a highly toxic explosive.
In the event of fire the surrounding area must be evacuated and
all personnel kept well upwind of the area.
Full fire fighting protective gear and
a self contained breathing apparatus operating in the positive pressure mode must
be worn for combating fire. Material near fires must be cooled with water spray to prevent ignition.
Fires should be allowed to burn themselves
out if not threatening to life or property. If fire is threatening to life or prop- erty use copious quantities of water to extinguish.
15.1.7 Ventilath
Local exhaust ventilation designed by a professional engineer should be provided if vapours, fumes, or dusts are gen- erated whilst working with airbag module.
The latest issue of the manual for recommended practices on 'Industrial Ventilation' is available from the
ACGIH Com- mittee on Industrial Ventilation, PO Box 16153, Lansing, MI 48910, USA.
The need for local exhaust ventilation should be evaluated by a professional industrial hygienist.
15.1.8 Respiratory Precauth
To prevent the inhalation of dangerous fumes and dusts, an approved mask should be worn.
15.1.9 Eye Protection
Chemical protective goggles are recommended where there is a possibility of eye contact with the propellant.
Safety glasses with side shields are recommended for
all other operations.
15.1. I0 Protective Clothing
Approved protective gloves, overalls and shoes / boots should be worn.
15.1.1 1 Handling and Storage Precautions
Do not store airbag module near live electrical equipment or circuitry. Store in a dry environment at ambient tempera-
tures.
Good housekeeping and engineering practices should be employed to prevent the generation and accumulation of
dusts. Store in compliance with
all local state and federal regulations.
15.1.12 Driver And Passenger Airbag Modules Assembly / Removal / Service Instructions
Before starting work, ensure ignition switch is in 'IocK position, key is removed and negative terminal cable
is disconnected from the battery.
As the airbag is equipped with a back up power source and due to the risk of airbag being inadvertently
deployed, wait one minute or longer before starting work.
0 Disconnecting the battery cancels the memory for clock, radio, seats, mirrors, steering column and any other
components using battery power. Reset memory after work is completed.
0 Never use airbags from other vehicles, always use new parts.
0 After work is completed, reconnect battery and perform warning light check see diagnostic manual.
0 Never use electrical probes to check voltage or electrical resistance.
0 Disconnect the airbag before carrying out any work on, or in the vicinity of module, or when using electric weld- ing equipment.
0 Always ensure that battery negative has been disconnected for one minute or longer before commencing any
removal procedure.

General Fitting Instructions
A3.2 GENERAL FITTING INSTRUCTIONS
A3.2.1
Always fit covers to protect the wings before commencing work in the engine compartment. Cover the seats and
carpets, wear clean overalls and wash hands or wear gloves before working inside the car. Avoid spilling hydraulic
fluid, anti
-freeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use poly- thene sheets in the boot to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or fitting caps.
Precautions Against Damage To The Vehicle
A3.2.2 Preparation
Before disassembly, clean the surrounding area as thoroughly as possible. When components have been removed,
blank off any exposed openings using greaseproof paper and masking tape. Immediately seal fuel, oil and hydraulic
lines when separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends
of oilways, exposed by component removal, with tapered hardwood plugs or readily visible plastic plugs. Immediately
a component is removed, place
it in a suitable container; use a separate container for each component and its asso- ciated parts. Before dismantling a component, clean it thoroughly with a recommended cleaning agent: check that the
agent will not damage any of the materials within the component. Clean the bench and obtain marking materials, la-
bels, containers and locking wire before dismantling a component.
A3.2.3 Dismantling
Observe scrupulous cleanliness when dismantling components, particularly when parts of the brake, fuel or hydraulic
system are being worked on. A particle of dirt or a fragment of cloth could cause a dangerous malfunction if trapped in these systems. Clean all tapped holes, crevices, oilways and fluid passages with compressed air.
WRNIFLG: DO NOT PERMIT COMPRESSED AIR TO ENTER AN OPEN WOUND. ALWAYS USE EVE PROTECTION
WHEN USING COMPRESSED AIR.
Ensure that any 'O'-rings used for sealing are correctly refitted or renewed if disturbed. Mark mating parts to ensure
that they are replaced as dismantled. Whenever possible use marking materials which avoid the possibilities of caus- ing distortion or the initiation of cracks, which could occur if a center punch or scriber were used. Wire together mating
parts where necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to
be renewed and to parts requiring further inspection before being passed for reassembly.
Place labelled parts and other parts for rebuild
in separate containers.
Do not discard a part which is due for renewal until it has been compared with the new part, to ensure that the correct
part has been obtained.
A3.2.4 Inspection
Before inspecting a component for wear or performing a dimensional check, ensure that it is absolutely clean; a slight
smear of grease can conceal an incipient failure. When a component is to be checked dimensionally against figures
quoted for
it, use the correct equipment (surface plates, micrometers, dial gauges etc.) in serviceable condition. The
use of makeshift equipment can be dangerous. Reject a component if its dimensions are outside the limits quoted,
or if damage is apparent. A part may be refitted if its critical dimension is exactly to the limit size and it is otherwise
satisfactory. Use Plastigauge 12 Type PG-1 for checking bearing surface clearance e.g. big end bearing shell to crank
journal. Instructions for the use of Plastigauge and a scale giving bearing clearances in steps of
0,0025 mm (0.0001
in) are supplied with the package.
