What is the likelihood of friction and detonations of detonating cord?

• A. Unlikely but still possible
• B. Very common
• C. Are unlikely but still possible
• D. Never occur

Answer: (C)

Friction is not a reliable trigger for detonating cord, which is designed to be initiated by a detonator rather than by everyday rubbing. In practice, detonation from friction is unlikely, but it can occur if the cord is damaged, crushed, nicked, overheated, or subjected to extreme friction or heat. So the risk is low, yet not zero. The wording that expresses these events as unlikely but still possible best fits because it conveys both the general safety expectation and the real, occasional exception. The other options either overstate the risk or suggest impossibility, which isn’t accurate. In real-world blasting safety, handle detonating cord with care, inspect for damage, and keep it away from rough handling, heat, and sparks to minimize any chance of unintended initiation.
