Which document serves as a key tool in informing employees about hazardous substance exposure?

The Safety Data Sheet (SDS) is essential for informing employees about hazardous substance exposure because it provides comprehensive information on each chemical's properties, hazards, safe handling practices, and emergency response measures. The SDS typically includes sections detailing the physical and chemical properties of the substance, health hazards, protective measures, and safety precautions for handling, storing, and disposing of the substance safely.

This document is required by regulatory agencies and serves as a critical resource for ensuring that employees understand the risks associated with their work and how to mitigate them effectively. It facilitates informed decision-making regarding the use of hazardous materials and enhances workplace safety by ensuring that employees have access to vital information regarding exposure risks and emergency procedures.

In contrast, other documents like written safety policies or safety training manuals may provide broader safety guidelines or procedures but do not offer the specific, detailed chemical safety information found in the SDS. Hazardous materials labels are also important but generally provide limited information compared to the comprehensive nature of an SDS. Thus, the SDS is the definitive source for data related to hazardous substance exposure.
