## Abstract

The Pipeline and Hazardous Materials Safety Administration is amending the Hazardous Materials Regulations applicable to air bag inflators, air bag modules, and seat-belt pretensioners. The revisions incorporate the provisions of two special permits into the regulations. In addition, PHMSA is amending the current approval and documentation requirements for a material classified as a UN3268 air bag inflator, air bag module, or seat-belt pretensioner. These revisions are intended to reduce the regulatory burden on the automotive industry and facilitate commerce, while continuing to maintain an equivalent level of safety.
