Hazardous Waste Operations and Emergency Response (HAZWOPER) is a set of regulations established by the Occupational Safety and Health Administration (OSHA) to protect workers involved in hazardous waste operations. It outlines safety procedures and training requirements for employees who handle hazardous materials, ensuring they are prepared to respond to emergencies effectively. The HAZWOPER standard applies to various situations, including cleanup operations, treatment, storage, and disposal of hazardous waste. It emphasizes the importance of personal protective equipment (PPE), site safety plans, and emergency response protocols to minimize risks and protect both workers and the environment during hazardous waste incidents.
