Booster is described as which of the following?

Booster is described as which of the following?

• A. Very high order 1.1D explosive used to prime blasting agents. Particularly if over 4 inch diameter.
• B. A small detonator
• C. A non-explosive device
• D. A fuse

Answer: (A)

A booster is a small, high-energy explosive charge whose purpose is to reliably transfer the initiation from the detonator to the main blasting agent. It sits between the detonator (the firing device) and the main charge and is sensitive enough to be detonated by the detonator, yet powerful enough to ensure the entire blast in the borehole goes off. This is especially important for larger diameter holes or more robust charges, where relying on the detonator alone might not guarantee detonation of the full charge. So the description “very high order explosive used to prime blasting agents, particularly if over 4 inch diameter” captures the booster’s role of providing the necessary initiation energy to start the main charge. It’s not just a detonator by itself, not a fuse, and not a non-explosive device.
