This Standard applies to the preparation of MSDSs for chemicals and materials1 used under occupational conditions. It presents basic information on how to develop and write MSDSs that are complete, clear and consistent. It also identifies information that must be included to comply with the HCS. Additional information is provided to help comply with state and federal environmental and safety laws and regulations. With the addition of certain data elements, this Standard is also acceptable for international use. This Standard is not intended to address the distribution of MSDSs.

This Standard is not intended to provide a rote specification for complying with the HCS or any other government requirements. Requirements change. It is the responsibility of the MSDS preparer to be aware of current HCS requirements.

1OSHA requires that an MSDS be prepared for chemicals that are hazardous according to the criteria described in the HCS. This Standard recognizes that MSDSs may be prepared for nonhazardous chemicals as well as hazardous chemicals. This Standard uses the term, material, to denote this wider scope of coverage.
