Hand - Arm Vibration: Risk Description
The Directive 2002/44/EC provides the following definition of hand-arm system transmitted vibration:
"The mechanical vibration that, when transmitted to the human hand-arm system, entails risks to the health and safety of workers, in particular vascular, bone or joint, neurological or muscular disorders.”
The hand-arm vibration exposure is generally due to hand contact with the handle of hand-held and hand-guided machinery.
Table 1 provides a list of tools that, when regularly used, entail, in most of cases, remarkable risks to workers arising from exposure to hand-arm vibration .
