Which of the following is correct regarding Safety Data Sheets (SDS)?

• A. They are optional
• B. They are for emergency responders only
• C. They are provided by the manufacturer or supplier
• D. They only cover physical hazards

Answer: (C)

Safety Data Sheets are official documents provided by the chemical’s manufacturer or supplier to communicate essential safety information about a chemical, including hazards, safe handling, and emergency measures. They are not optional; regulations require employers to have an SDS for each hazardous chemical and to make it accessible to workers. They are not limited to emergency responders; anyone who handles or uses the chemical should consult the SDS to understand risks and protective steps. They cover more than just physical hazards, detailing health effects, environmental hazards, first-aid measures, firefighting guidance, spill response, storage and handling, exposure controls, and regulatory information. This broad, regulatory-backed purpose is why the statement about being provided by the manufacturer or supplier is the best choice.
