Blasting Agents 1.5D are described as requiring what for reliable initiation?

• A. Require a higher order explosive for reliable initiation (emulsions, watergels, ANFO)
• B. Are self-contained high explosive compounds
• C. Do not require initiation
• D. Are identical to 1.1D explosives

Answer: (A)

1.5D blasting agents are designed to be relatively insensitive and safe to handle. Because of that insensitivity, they do not detonate on their own; they require a higher-energy initiating charge to start a detonation reliably. This means a booster or higher-order explosive is needed to transfer enough energy into the blasting agent so a true detonation occurs. Emulsions, watergels, and ANFO are typical blasting agents that fit this category, and they rely on that booster to ensure reliable initiation. They are not self-contained high explosives, they do require initiation, and they are not the same as 1.1D explosives, which are high-energy, runaway detonation devices.
