The measurement of whole body vibration in the workplace

A measurement system was developed to assess the amount of whole body vibration to which workers are exposed during routine operation of machinery in an industrial setting. This system is discussed in terms of plant structural design, production levels, direction and intensity of vibrational forces, measuring equipment, proper measurement technique and field application. Comparison of field data with ANSI and ISO fatigue-decreased proficiency boundaries indicated that small press operators were not at an increased risk for impaired work efficiency. Limitations of the field survey are presented and application of this system to other occupational environments is discussed.
