What is conveyed by Hazard Class markings and how are they indicated on munitions?

• A. Hazard Class 2; markings show Class/Division (2.x), UN number, lot number, quantity, and handling warnings.
• B. Hazard Class 1; markings show Class/Division (e.g., 1.1, 1.2), UN number, lot number, quantity, and handling warnings.
• C. Hazard Class 3; markings show only UN number.
• D. Hazard Class 1; markings show only Class/Division.

Answer: (B)

Hazard Class markings tell you the exact type and severity of a munition’s danger and what to do to handle it safely. For explosives, that means the marking shows Hazard Class 1 with a specific Division (1.x), which indicates the level of blast risk and how the item behaves in accidents. Along with that, you’ll see the UN number that identifies the material, the lot number for traceability, the quantity for shipping and inventory, and explicit handling warnings to prevent accidents. So this option is the best because it includes the correct class (1) and division (1.x) and all the supporting information—UN number, lot number, quantity, and handling warnings. The others mix in the wrong class or omit important data (only UN number, or only Class/Division), which would not provide the full, necessary safety information.
