Basic Corrections Officer: Certification Practice

Which of the following is a secondary high explosive?

1. Black Powder

2. Lead Styphnate

3. Mercury Fulminate

4. Nitroglycerin

The correct answer is: Nitroglycerin

The identification of secondary high explosives is essential in understanding the properties of various explosive materials. Secondary high explosives require a detonator to explode and are typically more stable and safer to handle compared to primary explosives. Nitroglycerin fits the definition of a secondary high explosive. It is known for its sensitivity to shock and friction, but it can still be safely handled in its stabilized forms. This characteristic allows it to be used in various applications, including in explosives for demolition and construction, where controlled detonation is required. It can also be used as a base for many formulations of more stable explosives. In contrast, options such as Black Powder, Lead Styphnate, and Mercury Fulminate have different classifications. Black Powder is classified as a low explosive, which ignites and burns rather than detonates. Lead Styphnate and Mercury Fulminate are both considered primary explosives; they are more sensitive and can detonate from impact or heat without the need for a detonator. Understanding the classifications of explosives, particularly the distinction between primary and secondary explosives, is crucial for anyone working in law enforcement, corrections, or related fields where explosive materials may be encountered.
