Abstract

We have compared the regulations of hot environment workpaces between Korea and ACGIH, then pointed out some insufficiences of Korean regulations for occupational hygiene and safety. And investigated the heat stress characteristics of laboratory, lathe and foundry working. The metabolic heat loads of those workplaces were obtained as 120, 300 및 660 kcal/hr based on WBGT index. WBGT index could be depended on weather condition, therefore useful for controlling working and rest times etc, but Belding-hatch index was represented by strength of working, definitely this would be convinient result for arranging countermeasures of workers in hot environments by estimating metabolic heat and signs of fatigue.
