In a Safety Data Sheet (SDS), hazard information is primarily found in which sections?

• A. Sections 3, 5, and 8
• B. Sections 9 and 10
• C. Sections 2, 11, and 12–13
• D. Sections 1 and 4

Answer: (C)

Hazard information focuses on what the substance can do to people and the environment, and how those hazards are communicated. The main place this is described is section 2, Hazard Identification, which gives the official classification, signal word, hazard statements, and pictograms that summarize the risks at a glance. To understand health effects in more detail, section 11 Toxicological Information expands on potential health hazards, routes of exposure, symptoms, and target organs. For environmental impacts, section 12 Ecological Information covers hazards to ecosystems, persistence, and degradability. Section 13 Disposal considerations ties the hazard characteristics to how waste should be handled, stored, or disposed of, reflecting regulatory and safety implications. While other sections like section 3 (composition) or section 8 (exposure controls) provide important supporting detail, the sections that most directly convey the hazard information are 2, 11, and 12–13.
