In terms of hazard communication, what is a Material Safety Data Sheet (MSDS) used for?

A Material Safety Data Sheet (MSDS) is essential in the realm of hazard communication because it serves as a comprehensive resource that provides detailed information about hazardous materials present in the workplace. This document is critical for ensuring the safety of employees, as it outlines the properties of the chemical, including its potential hazards, safe handling practices, protective measures, and emergency procedures. By having access to MSDS, employees can educate themselves about the substances they might be exposed to, thus enabling them to work safely and effectively within their environment.

In contrast, the other options do not pertain to the function of an MSDS. Summarizing employee qualifications, tracking attendance, and evaluating job performance involve administrative and managerial functions unrelated to chemical safety communication. The primary focus of an MSDS is to bolster workplace safety via informed handling of hazardous substances, making the correct answer clearly focused on providing essential information regarding hazardous materials.
