Caution: When you are carrying an undeployed inflator module:
• | Do not carry the inflator module by the wires or connector on
the inflator module |
• | Make sure the bag opening points away from you |
When you are storing an undeployed inflator module, make sure the bag
opening points away from the surface on which the inflator module rests.
When you are storing a steering column, do not rest the column with the bag
opening facing down and the column vertical. Provide free space for the
air bag to expand in case of an accidental deployment. Otherwise, personal
injury may result.
Live (Undeployed) Inflator Module
Take special care when handling or storing a live (undeployed) inflator
module. An air bag deployment produces rapid gas generation. This may cause
the inflator module, or an object in front of the inflator module,
to jettison through the air in the event of an unlikely deployment.
Scrapping Procedure
During the course of a vehicle's useful life, certain situations may
arise which will necessitate the disposal of a live (undeployed) inflator
module. The following information covers the proper procedures for
the disposing of a live inflator module. Deploy the inflator module
before disposal. Do not dispose of the module through normal disposal
channels.
Caution: In order to prevent accidental deployment of the air bag which could
cause personal injury, do not dispose of an undeployed inflator module as
normal shop waste. The undeployed inflator module contains substances that
could cause severe illness or personal injury if the sealed container is
damaged during disposal. Use the following deployment procedures to safely
dispose of an undeployed inflator module. Failure to dispose of an inflator
module as instructed may be a violation of federal, state, province, or local
laws.
Deployment Procedures
The inflator module can be deployed inside or outside of the vehicle.
The method used depends upon the final disposition of the vehicle. Review
the following procedures in order to determine which will work best
in a given situation:

gloves in order to protect your hands from possible heat and irritation when
you handle the deployed inflatable restraint front side impact module.
After the inflatable restraint front side impact module has deployed,
the surface of the air bag may contain a powdery residue. This powder consists
of primarily cornstarch (used to lubricate the bag as it inflates),
and by-products of the chemical reaction. The deployment reaction produces
sodium hydroxide dust (similar to lye soap). The sodium hydroxide quickly
reacts with the atmospheric moisture. This atmospheric moisture converts
the sodium hydroxide into sodium carbonate and sodium bicarbonate (baking
soda). Therefore, you will probably find no sodium hydroxide present
after the deployment. Gloves and safety glasses are recommended, however,
as a precaution. Gloves and safety glasses help to prevent possible
irritation of the skin or eyes.
