(57) [summary] The present invention is, mining equipment, underground transportation facilities, such as the one other similar to this, from the space with a long evacuation road, pollution caused by smoke, the load due to the heat, and hazardous under Kitanaka by a substance, it relates to a device for protecting the evacuation and rescue. Under the use of means for forming a mist, the characteristics of the mist, air is suitable for breathing for a relatively long time in the region below the at least smoke gas layer, is and holds state through at least light is used in obtaining such a method, therefore, the evacuation direction remains in recognizable condition. The present invention, spray nozzles 3 to form a mist, along the spray arch 2 is fixed, these spray arch, over the entire length of the evacuation journey of space and / or space, in tandem, and the evacuation direction in the transverse direction, so as to follow the upper space profile and / or evacuation journey of this space, are provided for. Over the entire length of the space and evacuation journey, the arched arrangement of the spray nozzle 3, the equipment on all structure is divided into sections, these spray nozzles, the basic flow 6 present in the equipment on the structure not interfere, therefore, the flow of the fluid or harmful substances smoke, not dammed by mist emitted.
