Determine the retreat route and avoidance of self-rescue methods. (2) When retreating, don't panic under any circumstances, don't run wildly, and retreat in an organized manner under the leadership of the shift leader and experienced workers. (3) People on the upwind side of the fire source should retreat against the wind. (4) In the fire downwind side of the personnel, the fire is small over the fire source is not dangerous, you can quickly cross the fire area to the fire source upwind side; or downwind withdrawal side, but must find a shortcut as soon as possible straight into the fresh wind flow in the retreat. (5) If it is not possible to evacuate safely within the effective time limit of the self-rescuer, you should replace the self-rescuer with one that is stored in a refuge, or find a place where there is a pressurized air piping system that provides compressed air for breathing, to avoid the fire and to wait for help. (6) Evacuation should be quick and decisive, but also fast and unruly. When retreating, you should rely on the side of the joint exit of the roadway to avoid missing the opportunity to get out of the danger zone. At the same time, you should also pay attention to the changes of the roadway and wind flow, and be careful of the possible reversal of the wind flow caused by the fire wind pressure. (7) If you are unable to escape from the fire or smoke, whether you are retreating upwind or downwind, you should quickly enter a refuge. If you do not have a refuge, you should choose a suitable location and use the site conditions and materials to quickly construct a temporary refuge before the smoke comes in.
