Evaluation of the effects of moisture on the thermal protective performance of fire protective clothing in low level heat exposures

This research sought to develop a better understanding of the effects of moisture on the mechanisms that contribute to heat transfer throughout turnout clothing materials in prolonged exposure to radiant thermal energy. It investigated the role of critical material variables, including the moisture vapor permeability and insulation properties of turnout composite ensembles. The scientific insights gained are expected to ultimately contribute to the development of laboratory test procedures for evaluating the thermal protective performance of turnout materials exposed to subflashover radiant heat conditions.
