Depending on the activities being conducted and the hazards present, response activities at worksites may be considered "emergency response" activities under OSHA's Hazardous Waste Operations and Emergency Response (HAZWOPER) standard, 29 CFR 1910.120 and 1926.65. In addition, cleanup sites may be considered or may become hazardous waste sites, requiring specific training and control measures, if certain criteria apply.
