Typically, how many sections are in a material safety data sheet (MSDS) or safety data sheet (SDS), and which section lists hazard identification and the signal word?

• A. Sixteen sections; Section 2 lists hazard identification and signal word
• B. Twelve sections; Section 3 lists first aid
• C. Eighteen sections; Section 1 lists product identification
• D. Fifteen sections; Section 4 lists exposure controls

Answer: (A)

In an SDS, information is laid out in a fixed set of sections, totaling sixteen. Hazard identification, including the signal word, appears in Section 2. The signal word (such as Danger or Warning) communicates how severe the hazards are, and placing hazard classification and related statements together in Section 2 lets you quickly grasp what hazards exist and their seriousness. The rest of the sections cover things like product identification, composition, and first aid, but the standard structure centers hazard identification in Section 2 for consistency and quick access.
