Verification method of strength of refractory slings for positioning and holding after exposure to a heated metal rod

Abstract

In the introduction of this work, three types of safety systems are considered when working at height. Hazardous factors have been identified that affect the safety of the user, depending on the components of the safety systems and their resistance to high temperatures. The purpose of this work is to improve safety in hazardous sectors of industry, construction and other types of work where increased protection of PPE components from sources of elevated temperatures is required, when working with gas and electric welding, as well as the resistance of materials to sparks from mechanical power tools. In the main part of the article, a new test methodology for refractory slings for positioning and holding was introduced, tests were carried out and the method was adjusted. The experience of the fire sector was borrowed, and in particular, the method in clause 9.8 from GOST R 53268-2009 Firefighting equipment was transferred and adapted. Fire rescue belts General technical requirements. Test methods”. The conclusions of adaptation and application of this method to other components of personal protective equipment are made.
