Description of change: On May 20, 2024, Federal OSHA updated its Hazard Communication Standard at 29 CFR 1910.1200. Washington State adopts these changes.
- Made updates consistent with the provisions of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS), primarily revision 7. Most recent updates (2012) were primarily revision 3.
- Updated scope of rule to include other hazards rather than strictly physical or health hazards.
- Added definitions for “bulk shipment,” “combustible dust,” “gas,” “immediate outer package,” “liquid,” “physician or other licensed health care professional (PLHCP),” “released for shipment,” and “solid.”
- Removed definition for “pyrophoric gas,” as the term is not used in the rule.
- The hazard classification must now include any hazards associated with the chemical’s intrinsic properties.
- Updated requirements for labels on shipped containers to apply to distributors.
- Updated labeling requirements for bulk shipments of hazardous chemicals.
- Updated requirements for safety data sheets.
- Updated trade secrets section to allow for either the specific identification of a hazardous chemical, and/or the exact percentage (concentration) or concentration range of the substance in a mixture.
- Updated appendices and related tables to meet OSHA requirements.
