Question: 1 / 400

What type of detonation occurs when a storage facility with high explosives detonates and its shock wave hits a nearby facility causing another explosion?

Deflagrate detonation

The correct answer is secondary detonation. This phenomenon occurs when the explosion from one source triggers an explosion in another nearby source, typically due to the shock wave created by the initial detonation. In the context of high explosives, the shock wave can propagate through the air or interact with a structural element, leading to a subsequent explosion of materials that were not directly involved in the initial blast.

Secondary detonations can be particularly dangerous, as they can happen in rapid succession after the first explosion, resulting in increased destruction and hazards. By understanding this concept, individuals working with or around explosives can take preventive measures to mitigate risks associated with potential secondary detonations.
