Hazardous Materials Handling 155
This class introduces best practices for safely handling, storing, transporting, and disposing of hazardous materials in the workplace. OSHA defines hazardous materials as any substance that can pose a physical or health hazard to employees. OSHA sets standards for hazardous materials in the workplace, including hazard communication, employee training, and PPE. In addition to OSHA, the Department of Transportation and the Environmental Protection Agency also set standards regarding the transportation of hazardous materials and hazardous waste disposal.
After taking this course, users will be aware of which regulatory agencies govern hazardous materials in the workplace, know key regulations and general best practices for hazardous materials safety, and understand how to find more specific information about the hazardous materials in their individual workplaces.
