Non-PFAS Moisture Barriers for Firefighters

Project Title: Assessing the Physiological Impact of Non-PFAS Moisture Barriers in Firefighter Turnout Gear

As the fire service transitions away from PFAS-based turnout gear, an urgent question remains: how do non-PFAS moisture barriers affect firefighter heat strain, cardiovascular stress, and overall physiological burden during demanding fireground activity? This project will evaluate those impacts through a multi-phase approach that includes field assessments with firefighters, laboratory testing of material and garment performance, and controlled environmental chamber studies. The research will compare PFAS and non-PFAS moisture barriers in terms of heat and moisture transfer, thermal protection, physiological response, cognitive effects, and overall performance under realistic conditions. The goal is to produce evidence-based guidance that supports the safe adoption of non-PFAS turnout gear, informs standards and procurement decisions, and helps reduce heat-related risk in the fire service.
