Which division covers Organic Peroxides?

Which division covers Organic Peroxides?

• A. Toxic Substances Division 6.1
• B. Infectious Substances Division 6.2
• C. Oxidizers Division 5.1
• D. Organic Peroxides Division 5.2

Answer: (D)

Understanding how hazmat divisions are organized helps here. Division 5 covers materials that involve oxidation-related hazards, and it’s split into two parts: 5.1 for oxidizers and 5.2 specifically for organic peroxides. Organic peroxides are organic compounds that contain a peroxide linkage (the O–O bond) and are known for instability and the potential to decompose rapidly, sometimes violently. That distinct hazard profile places them in 5.2, separate from pure oxidizers (5.1) and from infectious (6.2) or toxic (6.1) substances. So the correct classification for Organic Peroxides is Division 5.2.
