abstract="In order to quantitatively evaluate consequences of fire accidents in crowed places, dorm building was selected as a typical fire scenario, PyroSim software was used to obtain spatial-temporal distribution of toxic gases' concentration, and Pathfinder software was utilized to obtain such distribution of occupants' locations. Then, based on results output by the two software, data query algorithm written by Matlab code was adopted to obtain exposure concentration of occupants during evacuation, and average inhalation dose was calculated as an index to evaluate consequences of different fire scenarios. The results show that the consequence is the worst when fire occurs on the first floor. Opening two evacuation exits will greatly reduce impacts of fire accidents. As detection time decreases, average absorbed dose basically decreases linearly. When fire source is close to staircase, drop in detection time plays a greater role in reducing consequences. © 2021 China Safety Science Journal. All rights reserved.<p /><p>Language: zh</p>",
