Which items are included in HazCom as essential components?

• A. Labels, Safety Data Sheets, and training.
• B. Labels and training only.
• C. Labels, Safety Data Sheets, and training.
• D. Safety Data Sheets and labels only.

Answer: (C)

Hazard communication hinges on making hazard information accessible at the workplace. The three essential components are labels on chemical containers, Safety Data Sheets with detailed hazard information, and worker training so employees know how to interpret and act on that information. Labels provide immediate warnings and the basic hazards, SDSs offer in-depth details like handling, storage, and emergency measures, and training ensures everyone understands how to use both sources effectively in everyday work. Without a label, hazards may be misunderstood at the point of use; without an SDS, there’s no comprehensive reference for safe practices; without training, workers may not know how to read or apply the information properly. Therefore, including all three components—labels, Safety Data Sheets, and training—is the best, complete approach.
