OSHA hazard communication training can count toward DOT hazmat topics it covers. It does not count for the whole program by default. Compare the lessons with the worker’s transport duties. §172.704(b) PHMSA training FAQ, Q15
Give credit for content you can identify
Section 172.704(b) allows credit for qualifying OSHA, EPA and other agency training. Credit applies only to DOT topics those lessons cover. Check the content. A course name on a certificate is not enough. §172.704(b)
We suggest starting with the old course outline. Match each lesson to the DOT topic it covers. Mark a topic “not yet shown” if details are missing. Ask the provider for those details before giving credit.
Look for the transportation gaps
The course must teach the hazmat rules for the worker’s tasks. A workplace hazard lesson may leave transport paperwork out. It may miss other regulated work too. §172.704(a)(2)(i)
DOT security awareness lessons teach staff to spot possible transport security threats. They also teach how to respond. Check for both when you compare courses. §172.704(a)(4)
Covered staff need in-depth lessons on the required company security plan. They must learn how to carry it out. Chemical hazard lessons alone do not show that content was taught. §172.704(a)(5)
Record the combination you actually used
The employer must test staff on the required subjects. Its file must identify the materials used. It must also certify training and testing. Keep both credited and added lessons easy to trace. §172.702(d) §172.704(d)(3), (5)
For a filing aid, we suggest noting the source course. List the topics credited, gaps filled and materials location. This is an office note. It is not a new DOT form.
Who makes the final coverage decision?
The hazmat employer still has to comply when training is incomplete. Have the training lead check the full combined course before certifying it. §172.704(c)(4)
Your written procedure can assign that review. Say who compares courses and who fills the gaps. This lets useful prior lessons count. It also keeps missing transport topics visible.
