WebThe ASD is consistent with the Department's standards of blast overpressure (0.5 psi-buildings) and thermal radiation (450 BTU/ft 2 - hr - people and 10,000 BTU/ft 2 - hr - buildings). Calculation of the ASD is the first step to assess site suitability for proposed HUD-assisted projects near stationary hazards. WebΔP 0 = the overpressure (equivalent to p max − p 0 in equation 1, above), bar VBR = the volume blockage ratio Lf = the maximum distance a flame can propagate in the obstructed region (i.e., the run-up distance), m D = the average obstacle diameter, m Sl = the laminar flame speed of the flammable gas, m/s
