HazMat - The Occupational Safety and Health Administration (OSHA) requires all employees who potentially will work around or be exposed to hazardous materials (Hazmat) be trained before they begin working. Training includes an explanation of the hazards, how to handle hazardous materials, how to use personal protective equipment (PPE), how to minimize risks from hazards and medical surveillance requirements (monitoring and recognition of exposure symptoms). To aid trainers, OSHA has provided Publication 2254, Training Requirements in OSHA Standards and Training Guidelines.
