Which type of data is included on MSDS that describes potential health effects?

• A. Environmental data
• B. Physical properties
• C. Health hazard data
• D. Shipping data

Answer: (C)

Health hazard data describes what could happen to someone who is exposed to a chemical. It covers potential health effects from exposure, including acute reactions like irritation, dizziness, or burns, and longer-term issues from repeated or prolonged exposure. It also notes how exposure occurs (inhalation, skin contact, ingestion), signs to watch for, and recommended first aid measures. This section is dedicated to how the substance can affect health, which is why it’s the best answer for describing potential health effects.

Environmental data, physical properties, and shipping data cover different aspects: environmental data deals with the substance’s impact on air, water, and soil; physical properties describe characteristics like boiling point and density; shipping data covers safe transport and handling regulations.
