Which document provides essential information about chemical hazards and safe handling procedures in the pharmacy?

The correct answer is Material Safety Data Sheets (MSDS). These documents are crucial in a pharmacy setting as they provide detailed information about the properties of chemicals, including potential hazards, safe handling procedures, and emergency measures in case of accidents. MSDS sheets include data on toxicity, stability, and reactivity of the chemical substances, as well as guidance on personal protective equipment and first aid measures.

In the context of pharmacy operations, having access to MSDS is vital for ensuring the safety of healthcare professionals who handle hazardous materials and for complying with regulatory safety standards. The other options, while relevant in various contexts, do not specifically focus on the comprehensive safety information regarding chemical hazards and handling procedures that MSDS documents provide.
