| Outline of Final Research Achievements |
To reduce heat stress and strain at recovery work for the destroyed Nuclear Power Plant and construction work in summer, we developed a cooling method using a blower fan and a water spray (plus additional water immersion of extremities) and demonstrated its certain effectiveness in the laboratory experiment. Therefore, to examine the effectiveness at real outdoor work sites next, a commercially available mist fan having a cooling mechanism similar to our method was substituted for our experimental model to investigate how much effective the cooling method is for reducing the environmental heat stress at a construction work site. The study showed that the combined use of fan and water spray drastically decreased the WBGT value which is an indicator of heat stress suggesting that this method has remarkable cooling effect for reducing the environmental heat stress at outdoor work. Furthermore, the optimum distance between the object to be cooled and the mist fan could also be identified.
