Which federal regulation is commonly abbreviated as HAZWOPER?

Answer: A — OSHA Hazardous Waste Operations and Emergency Response

HAZWOPER stands for Hazardous Waste Operations and Emergency Response. This OSHA regulation sets the requirements for training, procedures, and safety practices for workers who conduct hazardous waste cleanup or respond to hazardous substance releases. That focus on hazardous waste operations and emergency response is why this regulation is the one commonly abbreviated as HAZWOPER and is the best answer. The other items refer to different laws or standards—SARA Title III (EPCRA) centers on emergency planning and community right-to-know, while NFPA 472 and NFPA 1072 are NFPA standards about responder qualifications and competencies, not the federal regulation named HAZWOPER. HAZWOPER is codified at 29 CFR 1910.120 (general industry) and 29 CFR 1926.65 (construction).
