What section of the MSDS would you reference for information about potential health hazards?

The correct section of the Material Safety Data Sheet (MSDS) to reference for information about potential health hazards is Section 3. This section specifically covers the hazardous ingredients and their associated health risks, detailing any potential effects on human health, such as acute and chronic effects from exposure to the substance.

Section 1 typically contains general information about the chemical, including its identification and company details, but does not provide detailed health hazard information. Section 6 may address accidental release measures and emergency procedures, while Section 15 deals with regulatory information. Hence, for understanding the health risks associated with a substance, Section 3 is the appropriate choice, as it focuses on the toxicological data and potential hazards directly related to health.
