Behind every Right-to-Know label there is a Material Safety Data Sheet. An MSDS provides more in-depth information about a chemical and the hazards associated with it. The MSDS also includes information on first aid and emergency responses, personal protective equipment, handling instructions, control measures, primary routes of entry, and other vital information necessary for the safe use of hazardous chemicals. To learn what is required on an MSDS, consult OSHA's Hazard Communication Standard 1910.1200 (g).
As with RTK labels, there are many ways to style and organize an MSDS. OSHA recommends the American National Standards Institute (ANSI) Z400.1-1993 standard for the preparation of an MSDS. However, it is ultimately up to manufacturers, importers, distributors, and employers to determine which format they use.
