HAZWOPER refers to the Hazardous Waste Operations and Emergency Response standard: 1910.120 (Division 2, Subdivision H). HAZWOPER is a complex standard – even explaining it is challenging. 

HAZWOPER protects employees who may be exposed to hazardous substances during cleanup work, at hazardous waste facilities, or when they respond to emergencies. HAZWOPER requires employers to follow specific work procedures to protect their employees. What the employees do - cleanup, disposal, or emergency response, for example - determines the procedures that employers must follow.​
