What is Hazard Communication (HazCom)?

Hazard Communication (often referred to as HazCom) is the set of processes and standards designed to ensure that information about the hazards of chemicals is properly classified and communicated to workers.

OSHA's Hazard Communication Standard (HCS)

Also known as the "Right-to-Know" law, OSHA's Hazard Communication Standard (29 CFR 1910.1200) mandates that employees have both a right and a need to know the identities and hazards of the chemicals they are exposed to when working.

The standard requires chemical manufacturers and importers to evaluate the hazards of the chemicals they produce, and prepare labels and Safety Data Sheets (SDS) to convey the hazard information.

Key Components of HazCom

• Written Program: Employers must have a written hazard communication program tied to their specific workplace.
• Chemical Inventory: A comprehensive list of all hazardous chemicals known to be present.
• Safety Data Sheets (SDS): Detailed informational documents prepared by the manufacturer or importer that describe the physical and chemical properties, hazards, and safe handling procedures.
• Labels and Warnings: Proper container labeling using the Globally Harmonized System (GHS) pictograms and signal words.
• Employee Training: Workers must be trained on the hazardous chemicals in their work area before their initial assignment and when new hazards are introduced.
