Which hazard class division is associated with a mass fire?

• A. 1.2
• B. 1.4
• C. 1.1
• D. 1.3

Answer: (D)

A fire hazard is the determining factor. When a munition or explosive material can burn readily and produce a large, spreading flame that could involve many items in an area, but does not create a significant blast or projectile danger, it falls under the fire hazard division. That’s what “mass fire” implies: a dangerous fire scenario involving multiple units rather than a high-order explosion. If the situation involved a massive detonation, that would be a mass explosion hazard; if projectiles or fragments were the main risk, it would be the projection hazard division; if the danger is only a small amount of risk beyond the packaging, it’s the minor hazard division. So the mass fire classification is the fire hazard division.
