Cloud dimensions	The radius of the cloud (R) $\mathrm{R}={\left(\frac{3\times \mathrm{V}}{2\mathsf{\pi }}\right)}^{1/3}$	(2)
Obstructed regions	a) $\mathrm{X}$ < 25 m b) $\mathrm{X}$ < 10 $\times$ D1 or $\mathrm{X}$ < 1.5 $\times$ D2
Explosion blast strength (overpressure)	${\mathrm{P}}_{\mathrm{s}}^{\prime }=\frac{{\mathrm{P}}_{\mathrm{s}}}{{\mathrm{P}}_{\mathrm{a}}}$, ${\mathrm{R}}^{\prime }=\mathrm{X}·{\left(\frac{\mathrm{E}}{{\mathrm{P}}_{\mathrm{a}}}\right)}^{1/3}$ ${\mathrm{P}}_{\mathrm{s}}={10}^{-\mathrm{b}·({\log }_{10}({\mathrm{r}}^{\prime }-\mathrm{c})}$
Positive phase duration	$t_p=\left(\frac{{\mathrm{t}}_{\mathrm{p}}^{\prime }}{{\mathrm{C}}_{\mathrm{s}}}\right)·{\left(\frac{\mathrm{E}}{{\mathrm{P}}_{\mathrm{a}}}\right)}^{1/3}$
