2. Hazards Identification

This section identifies the hazards of the chemical presented on the SDS and the appropriate warning information associated with those hazards. The required information consists of:

  • Classification of the chemical in accordance with paragraph (d) of 1910.1200
  • Signal word, hazard statement(s), symbol(s) and precautionary statement(s) in accordance with paragraph (f) of 1910.1200. (Hazard symbols may be provided as graphical reproductions in black and white or the name of the symbol, e.g., flame, skull and crossbones)
  • Describe any hazards not otherwise classified that have been identified during the classification process
  • Where an ingredient with unknown acute toxicity is used in a mixture at a concentration = 1% and the mixture is not classified based on testing of the mixture as a whole, a statement that X% of the mixture consists of ingredient(s) of unknown acute toxicity is required

3. Composition/Information on Ingredients

This section identifies the ingredient(s) contained in the product indicated on the SDS, including impurities and stabilizing additives. This section includes information on substances, mixtures, and all chemicals where a trade secret is claimed. The required information consists of:

For Substances
  • Chemical name;
  • Common name and synonyms;
  • CAS number and other unique identifiers;
  • Impurities and stabilizing additives which are themselves classified and which contribute to the classification of the substance.
For Mixtures

In addition to the information required for substances:

  • The chemical name and concentration (exact percentage) or concentration ranges of all ingredients which are classified as health hazards in accordance with paragraph (d) of 1910.1200 and
    • are present above their cut-off/concentration limits; or
    • present a health risk below the cut-off/concentration limits.
  • The concentration (exact percentage) shall be specified unless a trade secret claim is made in accordance with paragraph (i) of 1910.1200, when there is batch-to-batch variability in the production of a mixture, or for a group of substantially similar mixtures with similar chemical composition. In these cases, concentration ranges may be used.
For All Chemicals Where a Trade Secret is Claimed

Where a trade secret is claimed in accordance with paragraph (i) of 1910.1200, a statement that the specific chemical identity and/or exact percentage (concentration) of composition has been withheld as a trade secret is required.
