The cool water “extracts” the heat from the body (in heat transfer, the hot always moves to the cold), and then removes it from the body through evaporation. This works as long as the garment is wet and cooler than the body. When it warms up, all you have to do is wet it again with cold water. This method can be used indoor and outdoor.

radiation from flames, smoke, hot gas convection, and conduction from ,high temperature, surfaces [2]. Each of these ,heat transfer, modes has an impact on the thermal performance of fire fighters’ ,protective clothing,, and they all can independently cause burn injuries.

on ,protective clothing, and ,heat, stress was published in 1995 4) and updated for a conference in Adelaide in 20035). This paper provides another update of these two papers and a compilation of new research on ,protective clothing, against ,heat, and chemical agents with emphasis on their effects on thermal balance and performance.

6.4.1 Heat and moisture transfer through clothes Protective clothing aims to protect us against hostile environments, for instance thermal, biological, chemical or ballistic. Unfortunately, the materials and designs used for protective clothing hamper the transfer …

Flash fire ,temperature, can reach more than 800°C, and the ,heat, fluxes can be up to 80 kW/m 2. Textile ,protective, garments were used in the flash fire to prevent the skin burn and provide ,protection, against a ,high heat, flux environment.

Often, ,heat, and flame ,protective clothing, can meet more than one standard and additionally comply with other ,clothing protection, standards such as EN ISO 20471:2013 (,high, visibility), IEC 61482 (thermal hazards of an electric arc) and EN 13034: 2005 (chemical ,protection,).
