These parameters reveal the thermal response of protective clothing during the cooling period of the garment where heat transfer is influenced by the garment/fabric properties and/or the liquid flow. In addition, a predictive stored energy model and a burn evaluation model were proposed in order to determine the minimum exposure time for prediction of second degree burn in the cooling period.

Personal protective clothing (PPC) is required in many contexts such as hospitals that provide a range of barrier protection against blood, body fluids and viral threats in order to help maintain the sterile zone for both staff and patient safety. However, like other clothing, PPC, as an interactive barrier, could affect the heat loss efficiency.
