HAND TOOLS OPERATOR 'S HEALTH WORKSHOP ON MECHANICAL AND LEVEL OF RISK WHITE SYNDROME FINGERS

Workers in the metal industry are using the equipment (hand tool) that produces vibrations. These vibrations have a negative effect on the fingers, forearm, or shoulder joints. Disorders that often arises is often called the effects of hand arm vibration. These effects vary of workers, ranging from finger whitened condition to the inability to move the finger. Lack of security and safety equipment will further enlarge this negative effect, because the disturbance will result in declining labor productivity. This study aims to model safety equipment in the form of fluidic damper to reduce glove hand arm vibration. This objective will be carried out in stages: 1) obtain field data on working conditions, workload with a hand tool and type of equipment used, 2) determine the parameters of vibration hand tool that is widely used, 3) modeling and making fluidic damper glove, perform the test comparison of the use and without the use of glove, 4) glove on field trials that have been surveyed. In the period of the study for 2 years, each parameter vibration hand tools frequently used can be measured in the laboratory. Tests conducted to determine the vibration of the arms that operate hand tools. Fluidic damper glove designed to dampen vibrations in the arm so that its effect on health problems can be reduced.

Effect of Hand Arm Vibration on the Development of Vibration Induce Disorder Among Grass Cutter Workers

ObjectivesProlonged exposures to hand arm vibration among hand held machine user revealed caused development of vibration induce disability. The present study was to determine the effect of hand transmitted vibration by using hand numerical scoring and hand grip strength force assessment. MethodsA case study using adopted HAVS questionnaire and physical observation was investigated to a subject of 204 male workers from grass maintenance contractor. Two health effect assessments was done in this work comprises of severity stage of vascular and sensori-neural for both hand as well as the hand grip strength force. The correlation of workers experience between tow health effects was analyzed. ResultsMore than 90% of worker has been experience at risk hand grip stage for the both hand. Above stage 2 there were 172 workers (84.3%) with vascular disorder in the left hand while 163 workers (79.9%) with vascular disorder in the right hand. As for sensori-neural disorder, numbers of workers above stage 2 were 169 (82.8%) and 162 (79.4%) respectively. ConclusionThe results suggest that chronic health surveillance for hand arm vibration is under diagnosed in agriculture sector.
