Before using a chemical, which document should you refer to for safety information?

The Safety Data Sheet (SDS) is the correct answer because it provides comprehensive information about a specific chemical's properties, hazards, safe handling, and emergency measures. Each SDS is designed to ensure the safe use of chemicals in various environments, outlining necessary precautions, personal protective equipment (PPE) recommendations, first aid measures, and environmental impact considerations.

Referring to the SDS before using a chemical is crucial for understanding how to work with it safely and what to do in case of an accident, ensuring both personal safety and compliance with regulatory standards. Other documents, while potentially useful, do not contain the same level of detailed safety information specific to each chemical, making the SDS the most reliable source for immediate safety data.
