Abstract
For screening heat stroke during construction work in a hot environment, we measured the facial surface
temperature (FST) of construction workers using by thermography camera, with the heart rate, skin temperatures for the chest,
forearm, thigh, and lower leg, depth body temperature, activity, body weight, and water intake in experiments of an artificial
climate chamber and outside construction site in August. We verified the relatively significant correlations between the FST
and the mean skin temperature, thigh skin temperature and body weight loss in both sites
