Which document provides detailed chemical hazard information and handling instructions?

• A. Chemical Hygiene Plan (CHP) provides hazard information.
• B. Safety Data Sheet (SDS) provides detailed hazard information and handling instructions.
• C. Lockout/Tagout procedure.
• D. Permit-to-work record.

Answer: (B)

Safety Data Sheets provide detailed hazard information and handling instructions. They are the standard reference for a chemical’s dangers, safe work practices, required PPE, spill response, first aid, and proper storage. SDS documents follow a consistent format with sections on identification, hazards, composition, first aid, firefighting measures, accidental release measures, handling and storage, exposure controls and PPE, physical and chemical properties, and regulatory information. This makes the SDS the best source for both specific hazard details and practical steps to use a chemical safely.

A Chemical Hygiene Plan describes the overall lab program to minimize exposure through engineering controls, work practices, and PPE, but it does not replace the chemical-specific hazard details in an SDS. A lockout/tagout procedure is about isolating energy sources during equipment maintenance, not chemical hazards. A permit-to-work record authorizes high-risk tasks, rather than providing hazard data.
