Under §172.704(e)(1), as expanded by the HM-265 final rule effective February 13, 2026, a hazmat employee whose only HMR function is to manufacture, repair, modify, recondition, or test packagings — and who does no other HMR-regulated function — is not subject to Safety (Module 3) or Security Awareness (Module 4) training. The course explains exactly when this applies.
