Types of Explosives include which categories?

• A. Only manufactured explosives.
• B. Manufactured explosives (commercial and military) and homemade explosives (HME) which consist of oxidizers and fuel.
• C. Explosives subdivided into slow and fast speed categories.
• D. Homemade explosives are safer than manufactured explosives.

Answer: (B)

Explosives are broadly categorized as manufactured and homemade. Manufactured explosives include those produced commercially or for military use. Homemade explosives (HME) are improvised mixtures that typically combine an oxidizer with a fuel. This framing is the best answer because it captures the full, practical distinction used in training to assess risk, detection, and response. The idea of simply dividing explosives by speed (slow vs fast) is incomplete, and claiming that homemade explosives are safer is incorrect since HMEs can be highly dangerous and unpredictable.
