Comparative analysis of rescue operations to rescue a victims at a height

Abstract

A quantitative comparative assessment of the influence of the size of the rescue teams, as well as the level of preparedness of the rescuers-climbers on the time of implementation of various options for rescuing the victim by evacuation in an unsupported space, was carried out, which will contribute to solving the problem of reducing the time of rescue work at height without reducing the level of safety as a personnel rescue teams, as well as victims who require evacuation in an unsupported space. A comparative assessment of various options for height rescue operations was carried out, taking into account both the level of training of rescuers and the completeness of the rescue unit. with the help of both a spinal immobilization shield and rescue stretchers by the personnel of rescuers of the basic and initial level of training in groups of full and part-time staff in accordance with the criteria of Shapiro-Wilkie, Fisher and Student. It is shown that the time distribution of height rescue operations according to the options considered with a significance level of =0,05 can be considered normal. At the same time, the mathematical expectation of the time of height rescue work at height for the specified options differs significantly not only depending on the technical capabilities of the special equipment and safety devices used, but also on the level of preparedness of the rescuer-climber and the size of the rescue team. These properties must be taken into account when drawing up methodological recommendations for performing rescue work at height, as well as professional training of a rescuer-climber. The reliability of the obtained estimates was confirmed by comparison with the results of research conducted in 2018–2019.
