Which Hazard Division is associated with Mass-Explosion?

Explanation:
Mass-explosion describes a scenario where a single initiation can cause the entire quantity of explosive material to detonate, producing a very large, destructive blast that can affect a wide area. This is the highest level of blast risk within the explosives category, so it is the category associated with mass-explosion. The other hazard types within explosives refer to different failure modes—some emphasize projection of fragments, some involve a fire threat with little blast, and some describe only minor explosive effects—none of which match the broad, mass-detonation risk of mass-explosion.
