Introduction. The main task of the SNSS rescue units is to provide emergency assistance and rescue of the population in case of occurrence of events that threaten their life and health or may cause material damage. The success of rescuing people by fire brigades depends on several factors. First of all, it is the presence of special fire fighting equipment for rescue operations at the altitude and the technical possibility of its use. Today, the rescue of the victim from a sewage well, a water collector - a phenomenon is still quite widespread. Such cases come from the fault of the victim, yes, and due to negligence of the relevant utilities. Purpose. In rescuing people from multistory buildings, rescuers use motorbikes, but if the motorway can not arrive at an emergency, and manual fire ladders do not reach the required height, fire and rescue units use fire ropes and evacuate people with them.Rescue works in wells of underground communications are divided into the following stages: • Preparation of the necessary equipment and place of the event for the execution of works; • Emergency rescue directly into the well; • Preparation of the victim for lifting to the surface and transportation; • lifesaving on the surface. Methods. For descent from the floors or lifting from the underground well, the survivors of the survivors knit a double rescue loop from the fire rope and put it on the victim. But there is a better alternative to the double rescue loop - this is a rescue triangle. Results. Characteristics of the rescue triangle: time of dressing, comfort of dressing, durability, care of the rescue triangle.Conclusion. Equipping at least fire trucks equipped with rescue tripods, rescue triangles will greatly simplify the work and increase the efficiency of rescue works from the floors of the house or underground collectors (wells).
