Data concerning the effects of explosive blast on humans, structures, windows, etc. are available in standard texts. However, the non-linear relationships among the variables make it difficult to use the data in what if scenarios.

Hyperbolic equations which relate the energy of explosion (in term of TNT equivalent), distance from the explosion, blast pressure, blast impulse and degree of injury or damage to structures are developed. These relationships may be shown as straight lines on reciprocal-reciprocal graph paper. Thus, correlation of blast-effects data is simplfled, and fewer data points are required to characterize a damage-susceptible structure. Also, this type of graph aids in presenting the results of evaluations of potential damage which could result from accidental explosions, such as detonation of condensed explosives, pressure-vessel bursting, vapor-cloud explosions, and BLEVEs. Further, such graphs are useful in evaluating plant layouts and siting.
