Overview of the Hazard Communication Standard
Markedly, to ensure chemical safety in the workplace, information about possible chemical hazards must be available and understandable to workers. OSHA’s HCS requires the development and dissemination of that information:- Chemical manufacturers and importers must evaluate the hazards of the chemicals they produce or import. They must also prepare labels and safety data sheets (SDSs) to convey the hazard information to their downstream customers.
- All employers with hazardous chemicals in their workplaces must have labels and SDSs for exposed workers. Those workers must be trained on how to handle the chemicals appropriately.
Hazard Communication Standard Updates
Presently, the latest HCS updates align primarily with the seventh revision of the United Nations’ GHS. In particular, the updated standard requires labels on small packaging to be more comprehensive and readable. The updates also ensure trade secrets no longer prevent workers and first responders from receiving critical hazard information on SDSs. Additionally, workers will benefit from other changes, including:- updated physical hazard classes to better inform about the safe handling of explosives, aerosols, and chemicals under pressure; and
- revised precautionary statements on safely handling, storing, and disposing of hazardous chemicals.
