Which Hazard Division is Non-mass Detonating, Fragment Producing?

• A. 1.1
• B. 1.2
• C. 1.3
• D. 1.4

Answer: (B)

Non-mass detonating with fragment production means the explosive does not cause a mass explosion, but can eject fragments when it detonates. That combination points to a division that carries a projection or fragmentation hazard without a large, nationwide blast. In practice, this means you must account for potential shrapnel and debris harming people or equipment, even though the overall explosion isn’t a mass-detonation event.

The other divisions describe different hazard profiles: a true mass explosion hazard, or a fire hazard with little or no fragmentation or blast, or only a minor explosion hazard confined to the packaging. So the description “non-mass detonating, fragment producing” aligns with the division that has a fragmentation/projection concern without a mass explosion.
