Abstract: A production workshop was selected for emergency evacuation research, and PyroSim software was used for fire simulation. The variation law of temperature, visibility and CO concentration at 2 m from the ground at each exit with time was obtained, and the available safe evacuation time was obtained. Using Pathfinder software to establish an occupant evacuation model, the workshop occupant evacuation was studied, and the required safe evacuation time was obtained. It was judged that the workshop occupant could not be evacuated in time. The evacuation utilization rate of some exit was found to be low. Suggestions were put forward, such as guiding the workshop occupants to evacuate without changing the structure of the workshop, so that the workshop occupant could be evacuated safely. Occupant evacuation training should be strengthened, and emergency plans should be improved.
