When fuse and cap are used and the weather is snow, the minimum wait time is?

• A. 60 minutes
• B. 45 minutes
• C. 15 minutes
• D. 30 minutes

Answer: (D)

Weather affects how long you should wait after fusing and cap usage to ensure the area is safe. In snowy conditions, moisture and cold can influence detonator behavior and hide or delay clues of a misfire. Waiting thirty minutes provides a safety margin so any delayed detonation can reveal itself and the crew can verify that the charge did not fire or pose an unexpected hazard before approaching. The other options don’t give enough time for this added safety in snow, while 60 or 45 minutes isn’t typically required unless a specific site protocol calls for it.
