Introduction: 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 (CO2 welding) and Spot resistance welding operations.

.

Method and Materials: 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.

.

Results: Finding showed that the mean of welders exposure in GMAW and Spot resistance welding operations 5.61 ± 5.78and 2.38± 2.15 mg/m3, respectively(p<0.05). The results showed that in GMAW welders had the highe 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.

.

Conclusion: 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.

Introduction: work related musculoskeletal disorders are the most wide spread type of occupational diseases among workers. Awkward body postures during work and manual material handling are among the most important risk factors of musculoskeletal disorders in different jobs. Due to importance of recognizing these factors prevalence and risk factor of work related musculoskeletal disorders, this research was aimed to study the among employees of Kashan City’s Saipa automobile industry in 2011.

.

Material and Method: This study is a descriptive-cross sectional study conducted among workers with manual material handling 37 activities and 84 work duties. To recognize musculoskeletal disorders, body map questionnaire was applied and occupational risk factors were evaluated using Key Index Method (KIM). Data was analyzed using SPSS and Excel software.

.

Result: Highest prevalence of musculoskeletal disorders was in low and upper back region (%92). Based on the results from KIM, workers in the installing the tire, shuttle-aided fitting of seat, and engine work station had higher risk level with the scores of 66, 52 and 52, respectively. Risk level among three individuals (%3.6) was at 1, 40 (%47.6) at 2, 38 (%45.2) risk level 3, and 3 (%3.6) at 4.

.

Conclusion: Awkward body posture, improper twisting and flexion of low back were major risk factor among worker doing manual material handling tasks. Regarding the high prevalence of musculoskeletal disorders, appropriate ergonomic interventions such as engineering and organization interactions can reduce this risk factors (posture, heavy load, duration, workplace conditions) as much as the risk level reach to an acceptable level.

Introduction: Job satisfaction is a feeling of increased motivation, productivity and growth of personnel at work. Considering the negative effects of burnout, this syndrome can effect on occupational functions, such as quality of work, public health and job satisfaction. This study investigated the relationship between job satisfaction, general health and burnout is one of the automotive industries.

.

Material and Method: This study was a descriptive - analytical study conducted among. 120 workers in an automobile manufacturing industry in Tehran.the samples were selected using simple sampling method. Data were collected using, job satisfaction questionnaire Barry field, GHQ-28 and self-evaluation scale questionnaire. The data were analyzed using SPSS software.

.

Result: In this study 95% of individuals had low job satisfaction and moderated. In addition, 73/6% significant of people were likely to burnout, and 55% were people with mental health disorders. There was Inverse relationship between job satisfaction and general health the whole item. The direct correlation between the variables of general health and burnout, and there was a significant variable. The inverse relationship between job satisfaction and burnout, there was significant.

.

Conclusion: Given the obvious relationship between burnout and job satisfaction with public health, industry executives need to learn and improve incentive programs to promote employment, human relations and feelings of efficacy and bring into force.
