Which of the following is NOT a hazard from fires involving munitions?

Toxic smoke is not considered a primary hazard from fires involving munitions, although it may occur as a secondary effect. When munitions ignite or explode, the primary hazards include explosions with fragments, mass fires, and intense heat. These hazards are directly related to the physical properties and reactions of the munitions themselves.

Explosions with fragments refer to the shrapnel and debris produced when munitions detonate, posing significant risks to personnel and equipment nearby. Mass fires can erupt from the combustion of explosive materials, creating broad areas of danger and complicating firefighting efforts. Intense heat generated during these incidents can lead to severe burns and other thermal injuries.

While toxic smoke can be a concern in many fire scenarios, in the specific context of munitions fires, it is not the most immediate or defining hazard compared to the explosive and thermal risks posed directly by the munitions themselves. Understanding this distinction is crucial for safety officers when assessing and responding to incidents involving munitions.
