What are 'secondary explosives'?

• A. Explosives that are naturally occurring
• B. Explosives that require a detonator to initiate
• C. Explosives that are ineffective without fire
• D. Explosives that explode on impact

Answer: (B)

Secondary explosives are characterized by their need for a detonator or another high-energy initiator to trigger an explosion. This distinguishing feature sets them apart from primary explosives, which can detonate due to heat, friction, or impact. Secondary explosives are typically more stable and safer to handle, which makes them preferred for military and demolition applications. They are used in various ordnance and munitions, where a reliable and controlled initiation is necessary. This requirement for a detonator ensures that secondary explosives are used in a more controlled manner, enhancing safety in their storage and handling.
