| Abstract |
In this paper, the deterioration of quality and the increase of labor accident affected by hot weather ambience were analyzed and discussed from the viewpoint of environmental physiology as problems o...f human environment on construction. At first, the properties of hot climate were classified, severity of construction works was evaluated in relative metabolic rate(RMR), and temperature limit of works was shown as some index, such as the corrected effective temperature(CET). Because many processes were executed over the temperature limit, labor accident tended to occur in hot season, and particularly the fall accident from 1 p.m. to 3 p.m. when the temperature reached its peak. Especially, the frequency of heat attack occurrence highly correlated with the number of the days when the maximum temperature became higher than 30℃.show more
