ERGONOMIC CONDITIONS ASSESSMENT OF A BUS FACTORY

Abstract

Eventhough the production technology and capacity have been improved, manpower is indispensable. Coach production industry is one of the heavy industries. Production processes are mostly manpower in addition to automation and mechanization in these factories. Ergonomics is the one of the most important subject to increase the production efficiency and job security in heavy industry factories which use manpower heavily. Ergonomics is the field which aims to reduce the accidents and job related illnesses, anatomic problems in human body, psychological and physiological fatigue and minimize the workforce loss. Ergonomic statement evaluation is possible with providing ergonomic criteria such as anthrometric, environmental condition, and work place.

In this study, some experimental studies are done in order to evaluate the ergonomical conditions in chassis frame production, cataphoresis, paint shop, assembly, and quality inspection processes. The experimental studies include static and dynamic anthrometric measurements on a choosen process and experimental subject workers. The environmental conditions namely, temperature, humudity, lightening, air quality, and noise level are periodicly meausured with proper measuring devices and these data are recorded. The results are used to make an inference with comparing literature. Furthermore, inconvenient results are studied in order to determine the relation with work accidents, work related illnesses and total efficiency parameters in the factory. This study is considered to be a guidance for the effects of ergonomical conditions on workplace safety and health, work accidents and occurences, and production efficiency.
