An MSDS is a Materials Safety Data Sheet. It serves as an outline for employees and emergency personnel that explains the handling and disposing of potentially hazardous material in the workplace. OSHA requires MSDS be made available in the workplace, to local emergency personnel and in chemical shipments.
Material safety data sheets contain a variety of information about the material, including some of its physical properties, associated dangers, procedures for disposal and instructions for dealing with spills. MSDS forms produced in the United States have 16 separate sections. Thirteen of these sections are mandatory in all areas, while the additional three, all of which are related to the substance's effect on the environment, are only required in certain states.
