Can Your Outer Shell Handle High Thermal Loads?
The outer shell of a firefighter turnout probably has the most demanding role in the total configuration. It has two critical functions: to resist ignition from direct flame impingement and to protect the internal layers from rips, tears, slashes, abrasion, etc. Some turnout outer shell materials can have modest impact on TPP tests or can resist water absorption better than others. The real test of an outer shell material is its ability to maintain its protective qualities under high thermal loads and to stand up on the fireground.
