Who mandates the requirement for a Material Safety Data Sheet (MSDS)?

The requirement for a Material Safety Data Sheet (MSDS) is mandated by OSHA, which stands for the Occupational Safety and Health Administration. OSHA is responsible for ensuring workplace safety and health regulations in the United States.

The MSDS is a document that provides essential information about hazardous substances, including their properties, hazards, safe handling practices, and emergency responses. OSHA's Hazard Communication Standard (HCS) requires that employers maintain MSDSs for all chemicals used in the workplace to inform employees about the risks and safety measures concerning those substances.

Though other agencies like the EPA (Environmental Protection Agency) deal with environmental hazards and the CDC (Centers for Disease Control and Prevention) focuses on public health, including workplace safety in some scenarios, it is specifically OSHA that mandates the requirement for the MSDS as part of its commitment to protect workers from chemical hazards. The FDA (Food and Drug Administration), meanwhile, oversees food safety and pharmaceutical products, thus not directly relating to MSDS requirements.
