Proposition 65 & Safety Data Sheet Requirements

Question: What are safety data sheet (SDS) requirements, per the Occupational Safety and Health Administration (OSHA) guidelines associated with the California Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65)?

Answer: An SDS is a document produced in alignment with the United Nations (UN)'s Globally Harmonized System of Classification and Labelling of Chemicals (GHS) that the manufacturer, importer, or distributor of a chemical product is required to provide to downstream users. Safety data sheets and alignment with OSHA requirements play an important role in Proposition 65 compliance in occupational exposure scenarios.

An SDS includes information about the chemical it describes, such as:

  • The chemical's properties.
  • Physical, health, and environmental hazards associated with the chemical.
  • Appropriate protective measures.
  • Safety precautions for handling, storing, and transporting the chemical.

OSHA requirements require that information about concentrations of ingredients classified as health hazards must be included in Section 3. While these are the only substances that must be listed, many SDS creators also include more information.
