Which Hazard Division HD is Moderate Fire, No Significant Blast or Fragment?

• A. HD 1.1
• B. HD 1.2
• C. HD 1.3
• D. HD 1.4

Answer: (D)

Hazard Division 1.x classifications separate explosive shipments by the level of blast and fragmentation risk, with 1.4 representing a material that mainly poses a fire hazard and does not produce a significant blast or projectiles. When the description says there is a moderate fire risk but no significant blast or fragment hazard, that matches the 1.4 category, which is reserved for materials that can burn but are not expected to explode with a dangerous blast or throw fragments. The other divisions imply some level of blast or projection hazard (or a significant blast and fragmentation) that isn’t present here, so they don’t fit. Therefore, Hazard Division 1.4 is the correct classification.
