Summary

Equivalent TNT mass of 21.8 kg of released propane, and the factor by which every hazard distance grows, as a function of the assumed yield. Based on Iqbal and Salley (2004), pp. 15-9 to 15-11 and 15-18.

Original illustration for TNT equivalence, level 4 Expert.

Source basis: Iqbal and Salley (2004), p. 15-9 (Eq. 15-1, yield 0.01 to 1), p. 15-10 (Eq. 15-2, Table 15-2), p. 15-11 (Eq. 15-3), p. 15-18 (forklift example)
Alt text: Two rising curves against yield on a logarithmic axis: TNT mass from 2.2 to 224 kg and distance factor from 1 to 4.6.
