Periodic medical examinations are realized not rarer than once in 12 months
with the participation of internists, neurologists, otolaryngologists. At the inspection
it is necessary to realize capillaroscopy, measuring skin temperature, cold test, to
explore vibration, pain sensitiveness, if necessary radiography of hands, spine.

When working with vibrating equipment a duty cycle processing operation not
related to vibration is included. If this is not possible, it is necessary to provide for
10–15 minute breaks after every hour of operation.
It is noted that the adverse effects of exposure to vibration are enhanced in cold
conditions. Therefore, in the wintertime, it is necessary to provide workers with warm
mittens.
