Naval Special Warfare Explosive Ordnance Disposal (EOD) Proknow Practice Test

The distinction between low explosives and high explosives represents a fundamental classification within the field of explosives. Low explosives, such as black powder or smokeless powder, typically deflagrate, meaning they burn relatively slowly and create a large volume of gas, which can produce propellant effects, but they do not result in a rapid explosion. These types are often used in applications like fireworks and propellant for firearms.

In contrast, high explosives, such as TNT or dynamite, detonate and produce a shock wave due to their rapid decomposition. This makes them suitable for applications where a significant and instantaneous release of energy is required, such as in military applications or demolition.

The terms low and high explosives effectively encapsulate the primary characteristics that define how these substances behave under detonation, impacting their applications and handling. Understanding this classification is crucial for safety and operational effectiveness in handling explosives, making it essential knowledge for those in related fields.
