Division 5.2 refers to what category?

• A. Division 5.2
• B. Division 5.1
• C. Division 5.3
• D. Division 6.1

Answer: (A)

Hazard classification uses divisions within a class to pinpoint the exact hazard type. Class 5 is for oxidizing substances and organic peroxides, and its divisions specify the subtype: 5.1 for oxidizers, 5.2 for organic peroxides, and 5.3 for polymerizing substances. So Division 5.2 identifies the organic peroxides category. The other options point to different divisions within Class 5 or to a different class entirely (for example, Division 6.1 is toxic substances), which don’t describe organic peroxides.
