Which document identifies a chemical's approved users and physical health hazards?

The correct answer is the Material Safety Data Sheet (MSDS), which is now more commonly referred to as a Safety Data Sheet (SDS). This document is essential in the workplace as it provides comprehensive information about a chemical's properties, including its approved users, handling procedures, safety precautions, and potential physical health hazards. The SDS is designed to ensure that anyone who comes into contact with the chemical understands the risks involved and knows how to respond appropriately in case of exposure or an emergency.

The information contained in the SDS includes data on the chemical's composition, safe handling practices, first aid measures, and potential effects on health, enhancing safety in environments where hazardous substances are used. Having access to and understanding the SDS is critical for compliance with occupational safety regulations and for maintaining a safe workplace for all employees.

Other documents mentioned do not serve the same purpose as the SDS. For instance, Hazard Analysis Critical Control Point (HACCP) is a management system focusing on food safety, while shellstock tags are used for the identification and traceability of shellfish. A variance refers to a written permission to deviate from standard health code provisions and does not contain information about chemical hazards. Each of these has specific applications but does not provide the health and safety details
