Which document should be consulted to determine first-aid measures, fire-fighting measures, and personal protective equipment for a chemical?

• A. Certificate of Analysis
• B. Product Specification
• C. Safety Data Sheet
• D. Environmental Compliance Certificate

Answer: (C)

When handling a chemical, you want a single source that lays out all the safety and emergency steps for that substance. The Safety Data Sheet does just that: it consolidates hazard information and practical guidance, including first-aid measures for exposures, fire-fighting measures if the chemical catches fire, and the personal protective equipment and exposure controls needed during handling. These sections are specifically designed to guide responders and workers on what to do in emergencies and how to stay protected during use. The other documents serve different purposes—identity and purity (certificate of analysis), properties and specifications (product specification), or regulatory compliance (environmental compliance certificate)—and don’t provide the safety and emergency guidance in the same integrated way.
