shop gloves and safety glasses to protect your hands
and eyes from possible irritation and heat when
handling the deployed air bag assembly. After the air
bag assembly has been deployed, the surface of the
air bag may contain solid particulate. This solid

Put on a pair of shop gloves and safety glasses to
protect your hands and eyes from possible irritation
and heat when handling the deployed air bag
assembly.
After the air bag assembly has been deployed, the
surface of the air bag may contain a powdery residue.
This powder consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by products of the
chemical reaction. Sodium hydroxide dust (similar to
lye soap) is produced as a by product of the
deployment reaction. The sodium hydroxide then
quickly reacts with atmospheric moisture and is
converted to sodium carbonate and sodium
bicarbonate (baking soda). Therefore, it is unlikely
that sodium hydroxide will be present after
deployment.
WARNING: S A F E T Y P R ECAUTIONS MUST BE
OBSERVED WHEN HANDLING A DEPLOYED AIR
BAG ASSEMBLY. AFTER DEPLOYMENT, THE
METAL SURFACES OF THE AIR BAG ASSEMBLY
WILL BE VERY HOT. ALLOW THE AIR BAG

Deployment Outside Vehicle (Pretensioner
Seat Belt Assembly)
Deployment outside the vehicle is proper when the
vehicle is to be returned to service. This includes, for
example, situations in which the vehicle will be returned to
useful service after a functionally or cosmetically deficient
pretensioner seat belt assembly is replaced. Deployment
and disposal of a malfunctioning pretensioner seat belt
assembly is, of course, subject to any required retention
period.
For deployment of a live (undeployed) pretensioner seat
belt assembly outside the vehicle, the deployment
procedure must be followed exactly. Always wear gloves
and safety glasses during this deployment procedure until
a deployed pretensioner seat belt assembly is scrapped
or until an undeployed pretensioner seat belt assembly is
shipped. Before performing the procedures you should
be familiar with servicing the system and with proper
handling of the pretensioner seat belt assembly.
Procedures should be read fully before they are
performed.
The following procedure requires use of SRS deployment
harness with appropriate pigtail adapter. Do not attempt
procedure without adapter.
