Evaluation of workstation with the Finnish questionnaire
The Unsuitable workplace conditions make problems for workers and have some adverse effects on their health and reduce the rate of production in a plant. Poor designation or positions can reduce worker efficiency. The goal of this study was to evaluate various components of work environment including man and machines. They should be arranged around the operator in the workplace. Method: This is a cross sectional study. Samples are taken from Njafabad Co with 135 workers. Finnish questionnaire was completed by direct observation and interview with workers. Environmental condition, lighting, noise, heat stress was measured by means of related instruments. Results: The work site analysts rating in 24.3％ cases show that workers postures and movements are awkward. General physical activity analysts rating in 24.4％ cases show that the workspace, equipment and methods allow for adequate movement. In35％ cases arms in a position required by the work, slightly tens at a time. In10.8％ cases the back bended and 67.6％ cases poorly supported for the lower back. Accident frequency rate 31.6％ and frequency severity index of accident was 0.351.In 80％ cases there was no difficulty of making decision. Work is repetitive in 18％ cases. Lighting in 44％ cases is lower than standards one (P<0.05). The WBGT is 27.5 ?C and shows that workplace does not have any heat stress (P<0.05). Noise in 21％ of cases is higher than standards (85 dBA) and may be caused hearing loss (P<0.05). Conclusion: The analyses pointed to all categories of ergonomics problems were identified can causes of quality deficiencies, such as discomfort from strained parts of the body, ergonomically factors, time pressure and workplace conditions such as light, noise, heat stress, and the workers postures during work might affect human and can cause accidents and occupational diseases. The results of this study can be used in similar metal industries for reducing work stress.
