Minimum Criteria

The original “Minimum Criteria for Worker Health and Safety Training for Hazardous Waste Operations and Emergency Response (HAZWOPER)” (Minimum Criteria) was developed through a participatory national technical workshop in 1990 and issued by the NIEHS Worker Training Program (WTP) in 1991. This guidance was also published as a non-mandatory Appendix E to the Occupational Safety and Health Administration (OSHA) HAZWOPER standard. At various points since then, the Minimum Criteria document has been updated to reflect developments in training and the evolving priorities of the WTP. The most recent version, posted below, incorporates feedback from participants at the WTP Fall 2017 National Technical Workshop. The guidance is primarily intended for organizations that provide hazardous waste worker and emergency response training under grants from NIEHS, but may likewise prove valuable to any organization that provides similar occupational health and safety training.
