Which of the following is part of the correct misfire procedure?

• A. Wait appropriate time, attempt to reprime and refuse, wash hole, never pull on cap, wires, or primer
• B. Pull the cap immediately to test ignition
• C. Ignore the misfire and continue blasting
• D. Remove all charges and return to base

Answer: (A)

The thing being tested is how to handle a misfire safely. The best approach is to follow a controlled, safety‑focused procedure: wait the prescribed amount of time to allow any delayed ignition or gas buildup to dissipate, then re-prime and re-fire only according to established safety rules, wash the hole to dilute or remove any residual energetic material, and never pull on the cap, wires, or primer. Waiting reduces the risk of a second, accidental detonation and gives you a clearer picture of what’s happening. Re-priming and attempting a controlled second firing is done only if the protocol allows and after all safety checks are complete, not as a guess. Washing the hole helps clean out unburned materials and makes the area safer to re‑enter or re‑blast. Not touching the cap, wires, or primer prevents unintentional initiation. Other choices skip essential safety steps or involve actions that can trigger or conceal a dangerous misfire, which is why they’re not appropriate.
