Which SDS section contains toxicological information?

• A. Section 2 Hazard Identification
• B. Section 8 Exposure Controls/PPE
• C. Section 5 Fire-Fighting Measures
• D. Section 11 Toxicological Information

Answer: (D)

Toxicological information focuses on how a chemical affects human health, including acute toxicity, irritation, sensitization, and potential chronic effects. The Toxicological Information section of the Safety Data Sheet is where all of that health data is organized, including data like LD50/LC50 values, target organ effects, carcinogenicity, reproductive toxicity, and any observed chronic effects from studies. This makes it the best answer because the question is asking where health-effects data is stored. Other sections cover different topics: hazard identification explains what hazards exist and classifications; exposure controls/PPE provides recommended controls and protective equipment; fire-fighting measures covers procedures for fighting fires.
