Research Abstract |
This study was aimed to evaluate the conditions of occupational health and safety management and the work loads among workers belong to the organizations for excavating ancient objects. Percentages of the enforcement of the training cource of emergency revivification and the health examination among workers belong to the organizations for excavating ancient objects related to 47 Prefectural Board of Education were under 25%. The numbers of the occurrence of work related injuries and diseases among the organizations were significantly related to the numbers of the workmen employed by the organizations, and related to the lack of the regulations for occupational health and safety among them. During the 2-day survey in the mid summer, wet-bulb globe temperature (WBGT) in the afternoon of the first day and in the morning of the second day were over the occupational exposure limit for heat stress in the moderate work load. The tympanic temperarures increased during work, and decreased at rest. Maximal body temperatures were recorded before the first rest in the afternoon. In winter, the highest value of systolic blood pressure was observed at the starting time of work. This result might be mainly caused by the cold exposure in the excavating sites. Frequencies of some subjective symptoms in winter among workers with warm shoes were significantly higher than those among workers without warm shoes. However, there were no significant differences in percentages of workers who complained of coldness in the feet between workers with and without warm shoes. The values of WBGT under a special tent having the ability of intercepting UV were decreased in the summer when there was enough air movement in the place. These results suggest that wearing warm shoes and using special tent might be effective for workers to do excavating activities comfortably.
