Abstract: According to the investigation of a death-causing fire in an excavator parts warehouse, FDS was used to carry out numerical simulation and reconstruction. The burning situation of combustibles in the model was compared with the on-site investigation pictures. The heat release rate, temperature and gas concentration in the model were obtained. Assuming that water sprinkler was used, the data were analyzed and compared. Simulation results showed that the burning situation of combustibles in the model agreed well with the results of the on-site investigation. The temperature and the volume fraction of CO in the toilet where the deceased was located reached dangerous values. As the result, the main causes of death could be the joint action of high temperature burning, smoke poisoning and suffocation. If water sprinkler were used, the temperature and the volume fraction of CO concentration would be effectively reduced.

Key words: FDS, warehouse fire, burning situation, fire investigation
