Minimum Criteria

The original “Minimum Criteria for Worker Health and Safety Training for Hazardous Waste Operations and Emergency Response (HAZWOPER)” (Minimum Criteria) was published in 1991 as a non-mandatory Appendix E to the Occupational Safety and Health Administration (OSHA) HAZWOPER standard. Subsequently, the NIEHS Worker Training Program (WTP) published “Interpretive Guidance to the Minimum Criteria for Worker Health and Safety Training for Hazardous Waste Operations and Emergency Response” (Interpretive Guidance) in 1994. The WTP began the task of updating the Minimum Criteria/Interpretive Guidance through a technical workshop held in 2005. The final version of the Minimum Criteria document is included below. 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.
