Hazardous Materials: Approval and Communication Requirements for the Safe Transportation of Air Bag Inflators, Air Bag Modules, and Seat-Belt Pretensioners

Summary: In this NPRM, PHMSA is proposing to revise the Hazardous Materials Regulations applicable to air bag inflators, air bag modules, and seat-belt pretensioners. The proposed changes would incorporate the provisions of two special permits into the regulations. In addition, PHMSA proposes to revise the current approval and documentation requirements for a material appropriately classified as a UN3268 air bag inflator, air bag module, or seat-belt pretensioner. The proposed changes will, if adopted, reduce the regulatory burden on the automotive industry while maintaining the current level of safety.
