Early Fire Growth Rate in a Compartment: Prediction and Estimation of Steady State Heat Release

The prediction of the early fire growth rate in a compartment is problematic as is the estimation of steady state heat release in different scenarios. Consequently it can be argued that fire modeling is not as yet sufficiently well developed to be used to predict post ignition conditions in a compartment.’

a) Discuss the validity of this statement with reference to the basic stages in the growth and development of a fire, the processes involved, the influence of enclosure, ventilation, materials and the nature and extent of uncertainty associated with input parameters to fire models. Briefly describe the constituents of smoke and the factors that influence the relative proportions of each.
