Estimating Room Temperatures and the Likelihood of Flashover Using Fire Test Data Correlations

B. J. McCaffrey / J. G. Quintiere / M. F. Harkleroad

A simple procedure is presented for estimating room temperature and the likelihood of the occurrence of flashover in an enclosure. Upper room gas temperature from many fire test data sources is correlated with fire size, door opening, geometry and thermal properties of the enclosure. A cross plot of the data is then made at a prescribed hazardous temperature level yielding the flashover criteria. The fire safety engineer can use these results for quantitiative estimations of the effects of building design and fire load, for example, on the tendency for flashover as defined by a temperature limit.
