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

• A. 1.1
• B. 1.2
• C. 1.3
• D. 1.4

Answer: (B)

Understanding how Hazard Divisions describe what a material can do is essential for safe handling. When a division is described as non-mass detonating, it means there isn’t a risk of exploding the entire charge at once. Instead, the hazard is fragmentation: fragments can be produced and projected, but there isn’t a mass explosion involving the whole quantity. That combination—no mass detonation but fragmentation—directly matches the division defined for fragmentation hazards without a mass detonation.

So the correct concept is the division that specifically corresponds to fragment-producing behavior without a mass detonation. This is different from divisions that imply a mass explosion, or only a fire with minor blast, or other minimal explosion risks, which don’t fit the description of being fragmentation-producing without a mass detonation.
