One item found on an MSDS sheet is

• A. Health hazard data
• B. Manufacturer contact information
• C. Shelf life
• D. Disposal requirements

Answer: (A)

MSDS sheets are about communicating chemical hazards and how to stay safe. The item most central to that purpose is health hazard data, which tells you what health problems exposure to the chemical can cause, how severe those effects might be, what symptoms to watch for, and what to do in case of exposure. This helps you choose the right precautions—ventilation, handling practices, and the appropriate personal protective equipment. Other details like shelf life aren’t a standard focus of the MSDS, and while disposal guidance or contact information may appear, they’re not the core information the sheet is built to convey.
