After an electric misfire, how long must you remain away?

• A. 10 minutes
• B. 30 minutes
• C. 1 hour
• D. 2 hours

Answer: (B)

After an electric misfire, you must remain away for 30 minutes. This waiting period is necessary because an electric misfire can produce a delayed initiation; a charge may still detonate after a short delay even if the blast did not fire initially. Giving 30 minutes allows any potential delayed ignition to occur and helps keep the area safe before anyone re-enters. Shorter times risk exposure to a later detonation, while longer times aren’t the standard procedure unless directed by supervision.
