It has been more than 12 months since I took my initial HAZWOPER training or 8-hour HAZWOPER refresher. What should I do?.

If you have missed a refresher training course because of unavoidable circumstances, you should take the refresher course immediately. You may have to repeat your 24-hour HAZWOPER or 40-hour HAZWOPER training if too much time has passed since your initial course or last refresher. The time frame considered “substantial” will be determined on a case-by-case basis.

I am a scientist or engineer assigned to a contaminated site. What kind of HAZWOPER training do I need?

HAZWOPER refresher training is required for work at all contaminated sites, including that done by scientists and engineers. These sites are placed on the National Priority List (NPL) by the U.S. Environmental Protection Agency (EPA) and are scheduled for clean-up. The responsible party as identified in the EPA regulations, usually the site owner or past occupant, must cover the clean-up cost.
