Which statement accurately differentiates Division 5.1 and 5.2?

Which statement accurately differentiates Division 5.1 and 5.2?

• A. Division 5.1 covers organic peroxides; Division 5.2 covers oxidizers.
• B. Division 5.1 covers organic peroxides; Division 5.2 covers toxic gases.
• C. Division 5.1 covers acids; Division 5.2 covers bases.
• D. Division 5.1 covers oxidizers; Division 5.2 covers organic peroxides.

Answer: (D)

The key idea is that Class 5 is split into two distinct hazard types: oxidizers and organic peroxides. An oxidizer is a substance that can provide or release oxygen, helping fuels burn and potentially making fires worse. Organic peroxides, on the other hand, are organic compounds with a peroxide group that can decompose rapidly and violently, often with heat and shock sensitivity. So the accurate statement is that Division 5.1 covers oxidizers and Division 5.2 covers organic peroxides. Other options mix up these categories or refer to hazards that belong to other classes (for example, toxic gases are Class 2, not Division 5.2).
