HazCom

HazCom, short for Hazard Communication Standard, is an OSHA regulation that requires chemical manufacturers, importers, distributors, and employers to communicate the hazards of chemicals in the workplace. The standard mandates labeling of chemical containers, provision of safety data sheets, and worker training on chemical hazards and protective measures. It aims to ensure that workers can recognize, understand, and control chemical hazards regardless of the supplier.

Core elements of HazCom include hazard classification, labeling, safety data sheets (SDS), and a written hazard communication program. Hazard classification determines the physical and health hazards of a chemical. Labels convey these hazards at the point of use, and SDS provide comprehensive hazard information. A written program describes how the employer will implement HazCom requirements in their workplace.

Labels must include elements such as the product identifier, signal word, hazard statements, precautionary statements, pictograms, and supplier information. Safety Data Sheets provide detailed information in 16 sections, including identification, hazard identification, composition/information on ingredients, first-aid measures, firefighting measures, accidental release measures, handling and storage, exposure controls/personal protection, physical and chemical properties, stability and reactivity, toxicological information, ecological information, disposal considerations, transport information, regulatory information, and other information.

Implementation and scope: HazCom aligns with the Globally Harmonized System (GHS), introducing standardized pictograms, hazard statements, and precautionary statements. While administered by OSHA in the United States, HazCom is part of a broader international movement toward harmonized chemical hazard communication; many countries maintain equivalent requirements, such as EU CLP and Canada WHMIS.
