Binary explosives are Not USDOT rated and require what form of priming?

• A. Detonator or 50 grain cord priming
• B. Direct adiabatic initiation
• C. No priming required
• D. Electrical current only

Answer: (A)

Initiation energy must be delivered to binary explosives to trigger a reliable detonation, so a priming device is required. Binary explosives are designed to be safer to handle separately, but they still need a high-energy initiator to start the explosive reaction. A detonator provides that precise initiation, and blasting cord priming (often using a small charge carried by the cord) is another common way to transfer the detonation from the initiator into the explosive material. This is why using a primary initiation device or priming cord is the standard approach. Other options don’t fit because they either describe methods that aren’t standard priming means for these materials (direct adiabatic initiation), or they suggest no priming is needed (binary materials still require an initiation event), or they imply electrical current alone is sufficient without a detonator or cord to deliver the energy.
