Handling a Deployed Inflator Module

After the inflator module has 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. 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.
