Thermo-physical evaluation of firefighter outer garment in high flux environments

Thermal protective performance tests have been conducted and improved over the years to assess safety provided by firefighters’ outer thermal garments. Existing evaluation criteria based on empirical relations require an iterative process estimate skin burn injuries. In this work, concept of critical time – maximum exposure before physical failure, is proposed, utilized abate process. The relation fabric investigated at incident heat flux 41, 84 126 kW/m 2 . Furthermore, parametric studies are performed characterize thermo-physical behavior associated degree. tested specimens consist shell, a moisture barrier liner. methodology visual assessment as per ISO 6942 implemented approximate time. increasing displayed nonlinear reduction in garment. An increase second degree was observed for vertically oriented bench-scale test. firefighter’s current garment failed high relating cumulative will aid education firefighters fluctuating fire environments. This research opens new domain analyse garments utilising
