Which statement about Safety Data Sheets (SDS) is correct?

• A. They include hazard classification, handling, storage, exposure controls, and emergency measures.
• B. They describe the marketing strategy for a product.
• C. They are optional for most chemicals.
• D. They apply only to solid forms.

Answer: (A)

Safety Data Sheets provide the essential hazard and safety information for chemicals in a standardized format. They describe how hazardous a chemical is (hazard classification), how to handle and store it safely, what exposure controls and personal protection are needed, and what to do in emergencies. This matches the content and purpose of an SDS, which regulators require to protect workers and responders. The other statements don’t fit because SDSs aren’t about marketing strategies, they’re not optional for chemicals under OSHA/GHS rules, and they apply to all forms of a chemical, not just solids.
