When shipping any automotive hazardous materials, such as air bags, seat belt pretensioners, brake boosters, compressed gas shocks, batteries, paint, solvents, and other parts, to the Warranty Parts Center (WPC), dealership service agents must follow all hazardous material (hazmat) shipping requirements. (Fig. 14) The shipments must comply with applicable federal regulations, including being properly classified, described, marked, packaged, labeled, and in condition for shipment, and all persons performing the shipping functions in the dealership must be trained and certified.

Training and Certification

At least one person (and preferably two or more) at the dealership must maintain hazmat training/certification. Refresher training for ground transport is required every three years per federal regulation. There are several companies that provide training/certification.
