Handling Deployed Modules

After the air bag has been deployed, the surface of the air bag may contain a powdery residue. This powder consists primarily of corn starch (used to lubricate the air bag as it inflates) and by-products of the chemical reaction. Sodium hydroxide dust (similar to lye dust) 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. Always wear safety glasses and gloves when handling a deployed module, and wash hands with mild soap and water afterward.
