On the horizon: Is an “active thermal liner” in your PPE future?

By Battalion Chief Henry Costo, Philadelphia Fire Department — for LION Connects Historically in the fire service the measure of PPE quality and performance has been thermal stability. Materials such as PBI, Kevlar, Nomex, PBO, etc. were all developed to withstand changes during exposure to heat and flame. Indeed, most of the current standards-related testing has been designed to ascertain whether or not a fiber, fabric, composite, etc. possesses the required thermal stability. Recently, however, scientists at DuPont have taken a completely divergent approach to the issue of the thermal stability of turnout liner materials. They did so by inventing…
