In May 2024, OSHA introduced a new rule updating its Hazard Communication Standard (HCS) to improve protections for workers handling hazardous chemicals. This update aligns with the seventh revision of the United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS), ensuring that labels and Safety Data Sheets (SDS) provide clearer, more detailed information about chemical hazards.
One of the key changes in the updated standard includes enhanced labeling requirements, particularly for small packaging, ensuring labels are comprehensive and easy to understand. Additionally, the rule addresses how trade secrets should no longer obscure critical hazard information on SDS, especially for first responders. Updated hazard classification processes and new precautionary statements further enhance safety by improving guidance on handling hazardous substances like explosives, aerosols, and pressurized chemicals.
The revised HCS also aims to better align with the regulations of other U.S. agencies and Canadian standards, helping businesses maintain consistency across borders. These changes, set to take effect on July 19, 2024, are expected to reduce the incidence of chemical-related occupational injuries and illnesses by enhancing hazard communication in the workplace.
