ABSTRACT

The article contains a hygienic assessment of the influence of vibration on the muscular and working capacity of the workers using manual mechanical devices. The neuro-muscular state evaluation was performed with a manual dynamograph. 161 workers from different professional groups and a sample group of 26 workers were examined. The indices of the maximum muscular force and resistance to fatiguability proved to be the most informative ones. The most apparent neuro-muscular changes were found in the professional groups of moulders and mould-cutters, which could be related to the greatest dosages of vibration and intensive physical overload.

ABSTRACT

To limit the hazardous action of local vibration, a special nomogram was elaborated to determine, basing on newly established hygienic norms and regulations, the admissible duration of working with hand-operated vibrators. The normogram was based on the relation of vibrocontact duration to the vibration intensity, and was recommended to be applied to hand-operated vibrators with vibration intensity lower 10 cm/s (126dB).
