Net Explosive Weight & Quantity-Distance Calculator
Military and commercial blast standoff engineering: Net Explosive Weight (NEW) TNT equivalency factors, Inhabited Building Distance (IBD), and Public Traffic Route Distance (PTRD) perimeters.
01 Explosives Mass & Staging Geometry
02 Blast Overpressure & Q-D Telemetry STANDOFF APPROVED
Available staging yard separation exceeds DoD 6055.09-M Inhabited Building Distance. Blast overpressure at property boundary is within structural tolerance.
The Q-D Scaling Formula: D = K × W¹⁄³
The fundamental blast physics equation relates safe separation distance D (feet) to the cube root of the Net Explosive Weight W (lbs) multiplied by an empirical hazard severity factor K.
Inhabited Building Distance (IBD)
IBD (K40 to K50) protects inhabited structures from catastrophic collapse and personnel from serious blast injury, limiting incident overpressure to ≤ 0.9 to 1.2 PSI at the target perimeter.
Public Traffic Route Distance (PTRD)
PTRD (K24 to K30) ensures that highway motorists or main rail passengers passing an explosives staging area will not experience fatal vehicular rollovers or major projectile penetrations.
