Verification method of material stability of fire-resistant slings for holding and positioning against an open flame

Abstract

In the introduction of this work, the problem of the lack of test methods for personal protective equipment against falls from a height (hereinafter PPE), used in the areas associated with direct contact of PPE components with sources of elevated temperatures, is disclosed. The experience of the fire sector was adopted with fire tests for the impact of materials used in the production of PPE products in contact with an open flame. A number of tests were carried out on refractory slings for holding and positioning and the results obtained with a positive approbation of the method. The purpose of this work is to improving overall safety when working at height, to identify weak zones of protection of components of safety systems from various external factors that negatively affect them. Work was carried out and conclusions have been drawn about the application of this method on refractory slings for holding and positioning. One of the important requirements of customers of these slings in production is the resistance of materials of safety systems to the interaction of components in an environment of high temperatures. The conclusion of this work is the relevance of the application of this technique to the PPE sector, in particular to refractory slings for holding and positioning.
