Power tool use and occupational diseases

Has long been engaged in hand-transmitted vibration caused by the operations arm vibration disease as early as 1957 was listed as one of the statutory occupational diseases in China, also known as the local vibration disease, and typical manifestations of paroxysmal white finger.


Hand-held power tools, especially those built tools of the unbalanced mass of rotating parts, tools and equipped with eccentric device tool (such as hammer, electric breaker, etc.) with a crank and connecting rod piston shock device, motion will produce a large vibration. The operation of these tools, the vibration will be transmitted to the operator's hand, wrist and shoulder. With the extensive use of power tools, vibration hazards generated more and more attention.


Common occupational disease prevention measures: careful maintenance requirements in accordance with the manufacturer's instruction manual, and maintenance tools; When can rotate different tools as much as possible the use of a low vibration operation; should prevent the tool in the operator's hand generated around the cold gas and liquid;, if possible, in cold conditions, the operating handle of the tool should be heated; should avoid the use of sub-contact region within its handle the shape of the skin to produce a higher pressure tool; can choose, should be selected the tool requires a minimum contact pressure (grip force and feed force); damping gloves; operation, wear gloves to avoid damage to your hearing.
