What describes a non-electric system of detonating explosives?

• A. Eliminates all safety concerns
• B. Cannot be used in the field
• C. Requires no precautions
• D. Solves some of the safety problems but still require precautions

Answer: (D)

Non-electric detonating systems reduce certain initiation hazards by removing electrical initiation, which lowers the risk of stray currents, wiring faults, and unintended firing. This means they improve safety in one key area, but they do not eliminate all risks inherent in blasting. Precautions are still essential—proper handling, storage, inspection, and adherence to blasting procedures are required to prevent accidents and misfires. That's why the best choice says they solve some safety problems but still require precautions. The idea that safety is completely eliminated or that these systems can’t be used in the field or require no precautions isn’t accurate, since field use is common and ongoing safety practices remain necessary.
