During avalanche control work, if a misfire occurs, what is the recommended action before checking it out?

• A. Immediately inspect
• B. Wait 5 minutes
• C. Wait 30 minutes
• D. Do not check it at all

Answer: (C)

Misfires in avalanche control can leave a charge in a dangerous, unstable state. The safety rule is to wait a substantial, practical period before approaching to check it out. Thirty minutes gives enough time for any delayed detonation to occur and allows the device to cool and stabilize, reducing the chance of a sudden explosion when you re-enter the area. Inspecting immediately or after only a short delay can still expose you to a live threat, and not checking at all leaves a dangerous situation unresolved. After the waiting period, proceed with proper safety procedures and coordinate with supervision before attempting to re-enter the area.
