What are the key components of a Hazard Communication (HazCom) program under GHS?

• A. Chemical labeling, Safety Data Sheets (SDS), hazard pictograms, and staff training
• B. SDS, risk assessments, emergency drills, waste manifests
• C. Hazard pictograms only, training annually, labeling not required
• D. Chemical labeling, ventilation logs, PPE inventory, incident reports

Answer: (A)

Hazard Communication under GHS is about giving workers clear, standardized information about chemical hazards so they can handle them safely. The essential pieces are labeling of every chemical container with consistent details, Safety Data Sheets that provide in-depth hazard and safety information, the hazard pictograms that convey the type of hazard at a glance, and training to ensure staff can read labels, interpret pictograms, and use the information in the SDS. Labels typically include the product name, supplier, hazard statements, precautionary statements, and pictograms, while the SDS lays out hazards, first aid, safe handling, storage, and emergency measures. This combination ensures both immediate hazard awareness and access to detailed safety guidance. Other listed items—such as generic risk assessments, drills, or logs not tied to labeling and SDS requirements—do not constitute the core HazCom components mandated by GHS, and claims like labeling not being required or relying solely on pictograms without the full labeling and training also miss key elements.
