Hazardous wastes, when not handled properly, can pose a significant safety and health risk. OSHA recognized the need to improve the quality of the hazardous waste work environment and developed the HAZWOPER standard to provide employers and employees with the information and training necessary to improve workplace safety and health, thereby greatly reducing the number of injuries and illnesses resulting from exposure to hazardous waste.
