A Material Safety Data Sheet (MSDS) is a compilation of information required under the OSHA Hazard Communication standard on the identity of hazardous chemicals, physical and health hazards, exposure limits, precautions, personal protective equipment required when handling the material, and procedures that should be followed in the case of an emergency. The MSDS for a given material is provided by its manufacturer. EHS maintains an MSDS search page to assist in obtaining MSDSs.
