What is the PPV value for 301 to 5000 feet?

• A. 1.25 inches
• B. 1.00 inch
• C. 0.75 inch
• D. 1.50 inches

Answer: (B)

Peak Particle Velocity (PPV) is the maximum ground vibration from a blast, measured in inches per second. The allowed PPV typically decreases as distance from the blast increases to protect structures and people. For receptors located between 301 and 5,000 feet away, the standard limit is 1.0 inch per second. So the best answer is the value that matches this distance range. The other options would imply higher vibrations at that distance or be more restrictive than necessary for this range, which is why they’re not the correct choice.
