What section of the MSDS would contain information on emergency and first-aid procedures?

The correct choice pertains to the section of the Material Safety Data Sheet (MSDS) that provides vital information regarding health hazards associated with a substance. This section typically outlines potential health effects and specific emergency and first-aid procedures necessary for addressing exposure to hazardous materials. It guides responders on how to properly assist individuals who have been exposed, including the identification of symptoms and recommended actions depending on the type and severity of exposure.

This information is crucial for ensuring the safety and health of individuals in emergency situations, making it a fundamental component of the MSDS. Understanding health hazards and corresponding first-aid measures allows responders to act quickly and effectively, potentially reducing the severity of health impacts resulting from exposure.
