What is a key characteristic of thermal effects from a high explosive?

The key characteristic of thermal effects from a high explosive is that they have a short duration of effect. When a high explosive detonates, it produces an intense burst of heat in a very brief moment, resulting from the rapid energy release during the explosion. This intense heat can ignite fires or cause burns to individuals and materials nearby, but the actual thermal impact occurs in a fleeting period right after the explosion.

The short duration of thermal effects means that while the immediate impact can be severe, it does not persist for an extended time as might be the case with other types of thermal incidents, such as a prolonged fire. Understanding this characteristic is crucial for responders in assessing the risks and implementing safety measures during and after an explosive event.
