Seat Belt Tensioner: Service and Repair

For removal and installation. Refer to Seat Belts.
After deployment, a powdery residue may be on the surface of the pretensioner. The powder consists primarily of cornstarch (used to lubricate the bag as it inflates) and by-products of the chemical reaction. Sodium hydroxide dust (similar to lye soap) 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 (also known as baking soda). Therefore, it is unlikely that sodium hydroxide will be present after deployment. Wear gloves and safety glasses during the disposal procedure. Refer to "Deployed Airbag Module Disposal Procedure".
