METHOD OF USING POLYSPAST SYSTEM FOR CONDUCTING EMERGENCY AND RESCUE OPERATIONS IN A CONFINED SPACE (UNDERGROUND COLLECTORS, WELLS)

Abstract

Introduction. According to the information of the State Labor Office of Ukraine, over the 12 months of 2018, 59 persons were injured at the enterprises of the water supply and sewerage system of Ukraine, including 2 persons were fatally injured. Within 5 months of 2019, 16 people were injured, with 4 deaths.
 Water and sewerage managements of Ukraine is one of the most important systems of life support of settlements. Much of the water supply and sewerage network is in a state of disrepair and needs to be replaced and repaired. With the onset of summer, the intensity of repair, excavation and cleaning works, work in wells, ditches, trenches, closed spaces increases, which in turn increases the likelihood of accidents occurring during their execution.
 Appointment. Limited (closed) spaces include tanks (tanks, tanks, boilers), wells, chimneys, narrow passageways in tunnels and cellars, and the like.
 EAOUW - emergency and other urgent work.
 Feature of EAOUW in confined spaces is:
 - the possibility of accumulation of gaseous hazardous chemicals in high concentrations, explosive and poisonous gases, as a con- the difficulty of accessing rescuers to victims;
 - limited amount of time for EAOUW;
 - probability of landslides (landslides) during actions in earth wells;
 - a sharp rise in groundwater and displacement of the well rings;
 - threat of explosion or fire.
 Methods. As the equipment of the climbing and special rescue equipment of the units of the operational and rescue service of civil protection is different, we will consider the use of the system of polyspast during rescue operations in a limited space (underground collectors, wells).
 Results. Three experiments were conducted on the use of the polyspast system during emergency rescue and other emergency work in a confined space (underground collectors, wells).
 Conclusion.Having analyzed the above-mentioned facts of accidents at work in underground collectors, wells and standard of accessory, costs and terms of operation of fire-rescue, technological and garage equipment, tools, individual armament and equipment, repair and operational materials of subdivisions of Ukraine mounting method of polyspast system with different equipment. Particular attention should be paid to the third experience, namely the mounting of a polyspast system using six fire carbines and a rope.
