内容記述
The aim of the present study was to clarify an association between the prevalence of Raynaud’s phenomenon in workers using an impact wrench and the effect of various countermeasures to prevent adverse health effects of vibration over a period of 27 yr. The subjects were 704 workers who were regularly using an impact wrench and taking special medical examinations for vibration syndrome in a factory from 1981 to 2008. Practical countermeasures, such as improvement of an apparatus and control of working conditions, were taken twenty times. There were 39 subjects with Raynaud’s phenomenon at least one time during the observation period. The prevalence of Raynaud’s phenomenon decreased after introduction of the improved impact wrench. Thereafter, the prevalence of Raynaud’s phenomenon remained to be about 2–5 % although various countermeasures were taken to keep the working environments warm, reduce the working time, and improve other working conditions. These fi ndings showed that it is necessary to decrease the vibration level of an impact wrench to decrease the prevalence of Raynaud’s phenomenon.
