As a protective clothing for fire fighting which correspond to flames and a radiant heat is an air tight cloth, it is important to give off metabolic heat of the human body. So, we tried to examine the effect of head cooling for heat stress of fire-fighter in this study. The experiment were conducted under two conditions: ventilation with small ventilators and with coolants. The subjects were four healthy males. The skin temperature was calculated on 7 points of Hady & DuBois method. The skin temperature of neck, back thigh and the temperature within clothes, inside a helmet and external ear temperature were also measured in this study. The experiment was composed of the rest for 5 minutes, the exrcise of coresponding to 120 W/m^2 for 20 minutes and the rest for 5 minutes in the climatic chamber of temperature 30.0 ± 0.5 ℃, relative humidity of 50 ± 3%. The result were following: 1) The external ear temperature with head cooling was lower than that without head cooling. 2) The head cooling with small ventilator is more useful than head cooling with coolant.
