[Risk assessment of welders' exposure to total fume in an automobile industry]

Risk assessment of Toxic or hazardous chemicals enables the Industrial Hygienists to make the appropriate decision in providing healthy work place. This project was conducted in an assembling plant, [4workshop] of an Automobile Industry in IRAN with 2 types of welding operations, including GMAW [CO[2] welding] and Spot resistance welding operations. Welders exposures were assessed via collecting 143 breathing zone air samples based on NIOSH 0500 method. Risk assessment was carried out using Singapore recommended method. Finding showed that the mean of welders exposure in GMAW and Spot resistance welding operations 5.61 +/- 5.78 and 2.38 +/- 2.15 mg/m[3], respectively [p<0.05]. The results showed that in GMAW welders had the high exposure in comparison with Spot resistance welders [p<0.05]. The findings also demonstrated that the risk rate of GMAW welders were high, while this rate for Spot resistance was low. More hygienic attention is needed for GTAW welders. Control approaches are required including effective engineering control, conduct air monitoring, biological monitoring training, adopt respiratory protection program, develop and implement safe and correct work procedures and finally reassess the risk after all the controls have been done

[Prevalence of musculoskeletal disorders and work-related risk factors among the employees of an automobile factory in Tehran during 2009-10]

Work-related musculoskeletal disorders are considered as one of the most common occupational diseases and injuries. The high prevalence of the disorders has been reported in automobile industries due to numerous risk factors. This study was conducted to determine the prevalence of musculoskeletal disorders and the work-related risk factors in an automobile factory in Tehran. This cross-sectional study was performed on 145 workers in an automobile factory in Tehran during 2009-10. The prevalence of disorders was evaluated with standard Nordic questionnaire and work-related risk factors with KIM index. Data analyzed using chi-square test. Musculoskeletal disorders were most commonly seen in tire installing [92.8%] and exhaust storage installing [88.4%] units. It was least common in door installing [43.7%] unit. Awkward posture, load lifting, back bending and torsional movements were the most important work-related risk factors for the disorders. A significant relationship was observed between prevalence of musculoskeletal disorders and occupational risk level [P<0.05]. Ergonomics programs and specific ergonomic interventions are necessary to correct work-related problems in the work stations of this industry
