Which two main classifications are essential for explosive devices?

• A. Active and inactive explosives
• B. Primary and secondary explosives
• C. Commercial and military explosives
• D. High and low explosives

Answer: (B)

The classification of explosive devices into primary and secondary explosives is fundamental in munitions systems. Primary explosives are highly sensitive substances that can be detonated by heat, friction, or shock. They are often used as initiators in detonators or blasting caps because they require very little external energy to explode. Examples include lead azide and mercury fulminate. On the other hand, secondary explosives are more stable and require a significant amount of energy to detonate, typically provided by a primary explosive. They form the backbone of most explosive devices used in military and commercial applications, as they have a predictable performance under controlled conditions and are safer to handle. Common examples are TNT and RDX. Understanding this classification is crucial for handling, storing, and using explosives safely, as it directly impacts how they are deployed in various munitions applications. This knowledge ensures that personnel can design appropriate safety measures and recognize the appropriate applications of each type during operations.
