What is the PPV value for 5001 feet and above?

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

Answer: (C)

Peak Particle Velocity (PPV) is the maximum speed of ground movement caused by a blast, measured in inches per second. Regulations tie the allowable PPV to how far the receptor is from the blast. For receptors 5001 feet and farther, the Tennessee blasting practice specifies a maximum PPV of 0.75 inches per second. This far-field limit reflects the smaller vibrations reaching that distance while still providing a clear standard to prevent damage or nuisance. The other higher PPV values apply to closer distances, so they aren’t applicable at 5001 feet and above.
