HOT ENVIRONMENT
The aim of this research was to understand hot working environment at a construction site in summer. And its effects on health of workers. In construction site, some measures, such as taking a break during work.Setting tents and electric fans, and drinking cool water, had already been taken to reduce heat stress.
Hot environment or working outdoors during work varied from 23 to 34 degrees C. The time-motion study revealed that one subject worked exceeding 7 hours. And that the other one had little rest time and drank little water during work. Few items of subjective symptoms increased after work compared with before work. Blood sugar before work was significantly higher than before lunch and after work. Two subjects showed serum osmotic pressures increased after work. Hot environments can increase the blood pressure during work.
The measures seemed effective, because the effects of work were not remarkable in general. However, problems were still pointed out. Thus, stricter work control and health care for workers are necessary. such as controlling working hours strictly and monitoring the water intake during work
