Accident With Deployment Components Replacements
All SIR components must be replaced after a frontal crash involving air bag deployment. After deployment, a powdery residue may be on the surface of the air bag. The powder consists primarily of cornstarch, used to lubricate the bag as it inflates, and by-products of the chemical reaction. The sodium hydroxide then quickly reacts with atmospheric moisture and is converted to sodium bicarbonate, also known as baking soda. Therefore, it is unlikely that sodium hydroxide will be present after deployment. Replace the following SIR components:
- The SDM
- Air bag modules and pretensioners
- SIR wiring
- Clock spring
CAUTION:
Safety precautions must be followed when handling a deployed inflator module (air bag). After deployment, the inflator module (air bag) surface may contain a small amount of sodium hydroxide, a by-product of the deployment reaction, that is irritating to the skin and eyes. Most of the powder on the inflator module (air bag) is harmless. as a precaution, wear gloves and safety glasses when handling a deployed inflator module (air bag), and wash your hands with mild soap and water afterwards.
