Which document outlines protocols for handling hazardous materials?

The Material Safety Data Sheet (MSDS) is the correct answer because it is specifically designed to provide detailed information about hazardous materials, including their properties, handling protocols, and emergency measures in case of exposure. MSDS documents are essential for ensuring safety in the workplace, as they outline the potential hazards associated with the material, safe handling practices, personal protective equipment recommendations, and what to do in emergency situations such as spills or exposure.

In contrast, the Employee Handbook typically contains general policies and procedures relevant to all employees but does not focus solely on hazardous materials. The Occupational Safety and Health Administration (OSHA) Guidelines provide a broader set of regulations and standards for workplace safety but do not serve as a specific protocol for handling individual hazardous materials. Finally, the Safety Audit Report is an assessment of safety practices and compliance but does not provide the immediate detailed information necessary for the safe handling of hazardous materials like an MSDS does.
