| Abstract |
The incidence of decompression sickness (bends) has decreased in recent years because of strict control by regulations. Environmental hygiene, however, has seldom been discussed and little monitoring has been done. This investigation is the first of its kind in Japan; it covered most of the regions where compressed air work has been done in the past. Follow-up investigations were made for a period of 5yrs 10 months beginning in February 1980 on 55 places of caisson and shield work. The maximum bottom pressure in caisson work was 3.6kg/cm2 (4.6ATA) and that in shield work was 1.6kg/cm2. The number of exposures of workers was 23,737 in caisson work and 75,244 in shield work. The items measured included temperature, humidity, dust, illumination, noise, oxygen and carbon dioxide. Findings: the working temperature was controlled, but humidity was too high (nearly 90%); illumination was insufficient; dust was problem, but high humidity played an important role in limiting dust levels; the environment was noisy. |
