MSDS are documents, normally many pages long, that travel with or ahead of hazardous chemical shipments, warning users of the specific dangers of such products and guidance on their safe handling, storage and disposal. Evaluating chemical hazards and producing MSDSs and labels for downstream users are two of the key responsibilities chemical manufacturers and distributors have under the HCS.
The requirements for MSDSs are found in paragraph (g) of 29 CFR 1910.1200 . MSDSs must be developed for hazardous chemicals used in the workplace, and must list the hazardous chemicals that are found in a product in quantities of 1% or greater, or 0.1% or greater if the chemical is a carcinogen. The MSDS does not have to list the amount that the hazardous chemical occurs in the product. Specifically.They are required as a part of any compliance obligation to be available and displayed prominently in the workplace. The public has a right to MSDS data upon request.
They must be written in English and contain:
The name of the chemical (same as on the label)
The chemical and common names of the substance
A listing of the ingredients
A statement of the ingredients that are known carcinogens or that present other known hazards
Any specific hazards
