Abstract
This article provides a comprehensive analysis of the thermophysical properties of personal protective equipment (PPE) used in industrial and emergency environments. Protecting the human body from thermal damage under high temperatures and radiant heat is one of the key objectives addressed. The study evaluates three types of materials in terms of thermal conductivity, heat capacity, thermal resistance, and infrared reflectivity using both laboratory tests and numerical simulations in COMSOL Multiphysics. Additionally, a survey was conducted among workers operating in hazardous environments to assess the realworld effectiveness of PPE. The data collected enabled a scientifically grounded evaluation of the suitability of PPE materials for specific working conditions. The results serve as a basis for improving PPE design, developing next-generation protective clothing, and enhancing industrial safety standards.This research is relevant to sectors such as chemical production, metallurgy, oil and gas, and firefighting. Future research should include a comprehensive assessment of ergonomic features, physiological impacts on users, and the integration potential of smart sensors. Such scientifically informed approaches will not only improve workplace safety but also contribute to the overall quality of life and health protection of workers facing thermal risks.
