The purpose of this study was to clarify the scientific reasoning behind the occupational exposure limits for hand-arm vibration in Japan. Numerous publications from scientific journals and conference proceedings in the related field were checked for epidemiological data limited to studies of Japanese subjects containing vibration magnitude value and relation between prevalence of white finger and duration of exposure to hand-arm vibration. Prevalence of white finger in general population was investigated for comparing that in workers exposed to hand-arm vibration. Responses of peripheral circulatory and nervous functions in the upper extremities to acute exposure to hand-arm vibration were investigated and relation between the responses and characteristic of exposed vibration was analyzed. From the above data, the vibration magnitude value of 2.8 m/s^2 rms was considered to be appropriate as an 8-h energy-equivalent occupational exposure limit for hand-arm vibration in three axes and was proposed as an occupational exposure limit for hand-arm vibration in Japan.

本研究的目的是阐明日本手臂振动职业暴露限值背后的科学推理。对相关领域的科学期刊和会议记录中的大量出版物进行了检查，以获取仅限于日本受试者研究的流行病学数据，这些研究包含振动幅度值以及白色手指患病率与手臂振动暴露持续时间之间的关系。调查了一般人群中白色手指的患病率，并与手臂振动作业工人进行了比较。本文研究了急性手臂振动暴露对上肢外周循环和神经功能的影响，并分析了这些影响与振动暴露特点的关系。根据上述数据，认为2.8 m/s^2 rms的振动幅度值适合作为三轴手臂振动的8小时能量当量职业暴露限值，并建议作为日本手臂振动的职业暴露限值。
