Safety zone separation distance is an output computed in the BehavePlus fire modeling system based on the Butler and Cohen (1998) safety zone model; it is the core output of that model. Separation distance is 4 x flame height. Separation distance is calculated to prevent only radiant heat injury; exposure to convective heat is not accounted for in this model.
