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 in order to lubricate the bag as the bag 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 in order to prevent possible irritation of the skin or eyes.
