The analysis of large fire incidents indicate that most of fire casualties occurred during fire evacuation pass out to death by the smoke rather than fire itself. The purpose of this study is to investigate the characteristics of smoke movement in office building, and to analyze the influence of fire-induced toxic gas on the building occupancy involved in the fire evacuation. For this purpose, five compartment rooms and the adjacent corridor which is 20[m] long are built up. Fuels such as kerosene, polyurethane foam, unsaturated polyester and mixing of these fuels, are burned in the compartment room. The characteristics of smoke movement, such as the velocity of heat flow and time-dependent densities of the products, produced by the compartment fire are measured and analysised. In order to observe the pattern of smoke movement in detail, reduce-scale experiment (1:0.15) was tried. Also a transient numerical analysis of smoke movement was conducted by using commercial CFD software package.
