Specifically, you ask applies to other passenger-safety devices, such as roll-over protection systems. Roll-over protection systems contain a small amount of explosive material used to release a spring-loaded roll bar that will protect the occupants in a convertible vehicle. The explosive has previously been classed as a Division 1.4S explosive and assigned the approval number EX-1998030106. The exception in §173.166 does not apply to this type of device. You may wish to apply for a special permit from the Office of Special Permits and Approvals in accordance with procedures in § 107.105 of the HMR. I hope this answers you inquiry.
