Which document should be read when working with hazardous substances?

The Material Safety Data Sheet (MSDS) is essential when working with hazardous substances because it provides comprehensive information about those substances, including their properties, hazards, handling instructions, and emergency measures. The MSDS typically outlines critical information such as chemical ingredients, health hazard information, safe handling practices, and first aid measures in case of exposure.

Understanding the content of an MSDS is critical for ensuring safety in environments where hazardous materials are present. This document serves as a vital resource for anyone who may come into contact with chemicals, as it enables them to recognize risks and promotes safe practices to prevent accidents and injuries.

While other documents like Safety First Protocols, Hazard Assessment Reports, and Operational Safety Manuals may also contain relevant safety information, they do not offer the specific chemical hazard information that is crucial when dealing with hazardous substances. The MSDS is the go-to source for this level of detailed information, making it the correct choice in this context.
