Hazard communication is a system designed to inform workers about the potential hazards of chemicals they may encounter in the workplace. This includes providing information through labels, safety data sheets (SDS), and training programs. The goal is to ensure that employees understand the risks and know how to protect themselves. The Occupational Safety and Health Administration (OSHA) regulates hazard communication to promote safety and health in the workplace. Employers are required to maintain proper labeling of hazardous materials and provide access to SDS, which detail the properties, hazards, and safe handling practices for each chemical.
