What is the required time window between lighting the fuse and firing the shell to allow the shooter to retreat safely?

• A. 1 second
• B. 2 to 6 seconds
• C. 8 seconds
• D. 10 seconds

Answer: (B)

The time window is set to give you a brief but safe pause to retreat after lighting the fuse. After you light the fuse, there’s a short delay before the shell ignites and begins its ascent. A 2 to 6 second window provides enough time to move to the designated safe area before the shell rises, while not being so long that weather conditions or fuse variability could cause unpredictable behavior. If you waited only a second, you might not reach safety quickly enough in a real launch; waiting much longer than about six seconds increases exposure and risk if something goes awry. So the 2 to 6 second range is the balance that keeps you out of the danger zone as the shell fires.
