Some refinements have been made on a multi-room fire sread model. The primary improvements are: (a) that a model on excess fuel burning in arbitrary room has been introduced; (b) that a model for the prediction of gas concentrations has been added; (c) that subroutine ABSORB, which was created by Modak, has been introduced to predict the upper layer emissivity; (d) that a new fire plume model developed by McCaffrey has been included to remove the inaccureacy and inplausibility of a vertical point heat source plime model; and (e) that the code has been revised so that it can deal with tall buildings with somewhat less computer memory size.
