General Information - Health and Safety Precautions
Description and Operation Published: 11-May-2011

The Health and Safety Precautions subsection refers to some commonly used chemicals and materials, hazards associated with
their use, and safety measures to be taken. Some of these chemicals may be included in the following list either in their own
right or as an ingredient in a sealer or adhesive.

Acids and Alkalis

See also Battery Acids.
e.g. caustic soda, sulphuric acid.

Used in batteries and cleaning materials.

Irritant and corrosive to the skin, eyes, nose and throat. Cause burns. Can destroy ordinary protective clothing.

Avoid splashes to the skin, eyes and clothing. Wear suitable protective impervious apron, gloves and goggles. Do not breath
mists.
Ensure access to eye wash bottles, shower and soap are readily available for splashing accidents.
Display Eye Hazard sign.
Air Bags

See also Fire, Chemical Materials - General

Highly flammable, explosive – observe No Smoking policy.
Used as a part of the Supplemental Restraint System (SRS), mounted in various positions around the vehicle.
The inflator contains a high-energetic propellant which, when ignited, produces a VERY HOT GAS (2500° C).
The gas generant used in air bags is Sodium Azide. This material is hermetically sealed in the module and is completely
consumed during deployment. No attempt should be made to open an air bag inflator as this will lead to the risk of exposure
to Sodium Azide. If a gas generator is ruptured, full protective clothing should be worn when dealing with the spillage.
After normal deployment, gloves and safety goggles should be worn during the handling process.

Deployed air bags should be disposed of in a plastic bag in accordance with local regulations at an approved chemical waste
site.
Following any direct contact with gas generant.

Wash affected areas thoroughly with water
Seek medical assistance if necessary


WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted
before repairing or replacing any SRS components. To deplete the backup power supply energy, disconnect the battery negative
cable and wait for one minute. Failure to follow this instruction may result in personal injury.


NOTE: The storage, transportation, disposal and/or recycling of air bag modules must be carried out in accordance with all
applicable federal, state and local regulations including, but not limited to, those governing building and fire codes,
environmental protection, occupational health and safety and transportation.
Air Bags - Do's

Do store in an air bag safe when not installed to the vehicle.
Do store modules in an upright position
Do keep modules dry
Do carry modules with the cover side pointing away from the body
Do place modules with their cover side upwards
Do carefully inspect modules for damage
Do stand to one side when connecting modules
Do make sure all test equipment is properly calibrated and maintained
Do wash you hands after handling deployed air bags
Do wear safety glasses when carrying out repairs to the SRS or when handling an air bag module
Only carry out a system test with the air bag modules fully installed
Do inspect the condition of the impact sensor mounting bracket and sensor flylead if the vehicle has been involved in
an impact. Replace if damaged, even if there has been no deployment.
Air Bags - Do Nots

Do not store highly flammable material together with modules or gas generators
Do not store gas generators at temperatures exceeding 80° C

Supplementary Restraint System (SRS) Precautions

WARNING: Do not install rear facing child seats in the front passenger seat.

The SRS contains components which are potentially hazardous to service personnel if not handled correctly. The following
guidelines and precautions are intended to alert personnel to potential sources of danger and emphasise the importance of
ensuring the integrity of the SRS components installed to the vehicle.


WARNING: The following precautions MUST be adhered to when working on the SRS system:
The correct procedures must always be used when working on SRS components.
Persons working on the SRS system must be fully trained and have been issued with the safety guidelines.
The airbag modules contain extremely flammable and hazardous compounds. Contact with water, acids or heavy
metals may produce harmful or explosive results. Do not dismantle, incinerate or bring into contact with electricity
before the unit has been deployed.
Always replace a seat belt assembly that has withstood the strain of a severe vehicle impact or if the webbing
shows signs of fraying.
Always disconnect the vehicle battery before carrying out any electric welding on a vehicle installed with an SRS
system.


CAUTION: Do not expose airbag modules or seat belt pre-tensioners to temperatures exceeding 85° C (185° F).

It should be noted that these precautions are not restricted to operations performed when servicing the SRS system. The same
care should be exercised when working on ancillary systems and components located in the vicinity of SRS components; these
include but are not limited to:

Steering wheel airbag, rotary coupler.
Passenger front airbag.
Head airbag modules - front and rear.
Seat belt pre-tensioners.
SRS harnesses, link leads and connectors.
Side (thorax) air bags.
Making the system safe

Before working on or in the vicinity of SRS components, make sure the system is rendered safe by performing the following
operations:

Remove the ignition key.
Disconnect battery, earth lead first.
Wait 2 minutes for the SRS power circuit to discharge before commencing work.


NOTE: The SRS uses energy reserve capacitors to keep the system active in the event of electrical supply failure under
crash conditions. It is necessary to allow the capacitors sufficient time to discharge (2 minutes) in order to avoid the risk of
accidental deployment.
Installation

In order to make sure system integrity, it is essential that the SRS system is regularly checked and maintained so that it is
ready for effective operation in the event of a collision. Carefully inspect SRS components before installation. Do not install a
part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.


WARNING: The integrity of the SRS systems is critical for safety reasons. Make sure the following precautions are always
adhered to:
Do not install accessories or other objects to trim panels which cover ITS airbags.
Never install used SRS components from another vehicle or attempt to repair an SRS component.
When repairing an SRS system, only use genuine new parts.
Never apply electrical power to an SRS component unless instructed to do so as part of an approved test
procedure.
Special fixings are necessary for installing an airbag module – do not use other fixings and make sure that all
fixings are tightened to the correct torque.
Always use new fixings when replacing an SRS component.

CAUTIONS:
Take care not to trap airbag modules when installing interior trim components.
Make sure SRS components are not contaminated by oil or grease.
NOTES:


Following seat belt pre-tensioner deployment, the seat belts can still be used as conventional seat belts but will need to

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.

WARNINGS:


When handling an inflatable tubular structure (ITS) airbag module, hold by the gas generator housing, DO NOT hold by
the airbag. Do not wrap the thumb around the gas generator while holding. Do not drape airbag over shoulder or around neck.
For seat buckle type pre-tensioners, hold by the piston tube, with the open end of the piston tube pointing towards the ground
and the buckle facing away from your body. Do not cover the end of the piston tube. DO NOT hold buckle type pre-tensioners
by the bracket assembly or cable. Never point the piston tube towards your body or other people.


Airbag modules and seat belt pre-tensioners are classed as explosive devices. For overnight and longer term storage,
they must be stored in a secure steel cabinet which has been approved as suitable for the purpose and has been registered
with the local authority.


Store airbag modules or seat belt pre-tensioners in a designated storage area. If there is no designated storage area
available, store in the locked luggage compartment of the vehicle and inform the workshop supervisor.


CAUTION: Improper handling or storage can internally damage the airbag module making it inoperative. If you suspect
the airbag module has been damaged, install a new module and refer to the deployment/disposal procedures for disposal of
the damaged module.
SRS harness and connectors

Always observe the following precautions with regards to SRS system electrical wiring:



Never attempt to modify, splice or repair SRS wiring.
Never install electrical equipment such as a mobile telephone, two-way radio or in-car entertainment system in such a
way that it could generate electrical interference in the airbag harness. Seek specialist advice when installing such
equipment.


NOTE: SRS wiring can be identified by a special yellow outer sleeve protecting the wires (black with yellow stripe
protective coverings are sometimes used). www.JagDocs.com
