Assessment of exposure to hand-arm vibration and its related health effects in workers employed in stone cutting workshops of Hamadan city

The workers employed in stone cutting workplace are exposed to hand-arm vibration and its complications. The aim of this study was to evaluate the exposure to hand-arm vibration and its health effects on workers in the stone cutting workshops.
In this descriptive-analytic study, 40 workers of Hamadan city stone cutting who worked with stone cutting machines were examined. Measuring exposure to hand-arm vibration was performed by standard methods ISO 5349. Symptoms related hand-arm vibration syndrome using a questionnaire construction was studied. Data were analyzed using SPSS software.
Results showed that 8-hour equivalent acceleration of hand-arm vibration exposure in stonecuttingworkers was exceeds the permissible exposure levels of country (Pv In regard to exposure level of stone cutting workers compared with the national exposure limit, the training of health care, non-smoking, and use of anti-vibration gloves, work rotations canthe effective in reducing the risk of health effects. Furthermore, it seems essential to track the health effects associated with human vibration by use of screening tests in the work place seem.
