White finger syndrome, also better known as “dead finger”, is usually caused by continuous use of hand-held machinery. It is also known as HAVS (i.e. hand or arm vibratory syndrome). White finger disease is very widely spread by the workers. It is mainly an industrial hazard that affects the blood, blood vessels and nerves of the victim.
Most of the injuries can be found between 5 Hz – 2000 Hz but the most risky injury is when it occurs at about 150 Hz. It can be resulted in different forms but all of them are usually known as white finger syndrome. This problem is most effective on the arm and the forearms.
Usually, the ailed can’t notice and continue working for a day when it turns white and numbness is unnoticeable. If it is not stopped at the right time then even the knuckles start becoming white with loss of feeling in the arms. It is understood that when we are hurt with knuckles, mostly the grip of our effected hand is lost. Professor Giovanni Loriga of Italy first recognized the symptoms of this disease in 1911. She later reported about this theory and also a link between white finger syndrome and cold weather symptoms in 1918.
To prevent this, we need to use a tool which vibrates quite longer and can be used equal to the working of a heavy vibrating tool. The duration of the tool should be measured by ‘trigger time’. Trigger time is the time when the worker’s finger is on the vibrating trigger and the time it is totally used per day. According to the best example of health and safety execution, which gives the instance of the hammer drill, in which the trigger time varies from 6 m/s2 to 25 m/s2. The best intention for the workers should be to supply them better-designed and maintainable tools so that they can work appropriately.
Vibration can also be reduced by different tools designs. Vibrations are mainly found by the comma tools like hammers, drillers and excessively used instruments including drilling machine used for the purpose of digging roads.
