What is the minimum fuse length for a single charge or loaded shot when it is the only charge fired in the same working place?

• A. 0.5 meter
• B. 1 meter
• C. 1.5 meter
• D. 2 meters

Answer: (B)

When you ignite a single charge in a working place, you want enough time for you to move to a safe location before the blast goes off. The fuse length provides that retreat time. For this situation—the only charge fired in that place—the minimum length that still gives a safe withdrawal window is one meter. A shorter fuse would not give you adequate time to reach safety, while longer lengths aren’t required for a single charge and would simply slow things down unnecessarily. If there are multiple charges or other firing conditions, fuse lengths are adjusted to ensure safe separation, but for one charge the shortest safe length is one meter.
