Abstract:

A fire in a kitchen in Sharon, Pennsylvania killed three persons in upstairs bedrooms, one with a blood carboxyhemoglobin content of 91%. Considerable physical evidence remained. The fire was successfully simulated at full scale in a fully instrumented seven room test called Sharon 2. The data are used to evaluate the precision of two multiroom fire codes: FAST 18 and HARVARD 6.3. During the simulation, a coherent ceiling layer flow was observed that quickly carried high CO concentrations to remote compartments. Such flow is not directly accounted for in either fire code. However, both codes well predict the CO buildup. Prediction of temperatures was less successful. Hypotheses are presented as to the reasons for the differences. At least some are believed due to phenomena not in the codes.
