Statistical Methods for Analysis of Safe Use of Special Rescue Equipment, Part I.

Abstract

Due to ever increasing extremities of disasters and accidents, rescue operations have become more and more complicated, requiring both theoretically and practically better qualified rescue personnel. It is a serious problem that methods of using special rescue equipment, rely in many cases only on oral-based communication, while the offer of new
equipment’s developed by manufacturers is growing dynamically. Such a change in the
rescue equipment can also be observed in the case of rescue work with rope rescue technique where the safe use of equipment is vital.
The purpose of the study, based on mathematical statistical processing of the results of a specially designed questionnaire research, is to answer the question how the users evaluate to the usage safety of three selected rope technological devices. An additional purpose was, based on these results, to make suggestions on improving usage safety concerning these devices.In my first part of my study, I analyze the results of the Mann-Whitney test and Spearman's correlation.
