How far away from the ignited charge should the avalanche blaster be?

• A. 100 feet behind a terrain barrier
• B. 50 feet behind a terrain barrier
• C. 150 feet behind a terrain barrier
• D. 200 feet behind a terrain barrier

Answer: (A)

When you ignite an avalanche blaster, you’re dealing with a powerful blast that sends a shock wave and flying debris outward. The terrain barrier acts as a shield, interrupting the direct path of fragments and helping to absorb some of the energy. Placing personnel or equipment 100 feet behind that barrier gives a safe buffer where the blast effects are significantly reduced, lowering the risk of injury from high-velocity fragments or pressure changes. Closer than 100 feet increases danger, while being farther away is not required by the standard procedure and would just slow operations. So the required minimum distance behind a terrain barrier is 100 feet.
