Where can information on the chemical and physical properties of mercury be found?

The Material Safety Data Sheet (MSDS), now commonly referred to as Safety Data Sheet (SDS), is the correct source for finding information on the chemical and physical properties of mercury. These documents are specifically designed to provide detailed information about the hazards of chemicals, including their physical and chemical properties, handling, storage, and emergency measures in case of an accident.

The MSDS/SDS is a critical resource for ensuring safety in environments where hazardous materials are present. It offers comprehensive details such as the chemical composition, toxicity levels, and potential health effects associated with exposure to mercury. This information is vital for maintaining a safe working environment and ensuring compliance with safety regulations.

The other options, such as patient record files, local guidelines, and cleanliness audits, do not provide the specific chemical and physical properties of mercury. Patient record files focus on individual health information, local guidelines pertain to procedural standards or operational policies, and cleanliness audits evaluate the hygiene and sanitation practices rather than detailed chemical data.
