In this study, the use of work study technique in the analysis of physical risk factors of noise, lighting, temperature and relative humidity in occupational health and safety was investigated. Applied research for work study studies and physical risk factors measurements was carried out in the dye-finishing plant of a large-scale textile factory operating in the Çukurova/Turkey region. The entire production process and activities in the enterprise were recorded in the developed work study forms, which included occupational health and safety risk factors, through direct and random repeated observation. All activities were evaluated together with physical risk factors and work study technique. Within the scope of occupational health and safety, the risks in the paint finishing business could be determined with the help of the work study technique. It has been observed that the paint finishing business has a high risk especially in terms of temperature and humidity. Unnecessarily high lighting level was found in the enterprise. For energy efficiency, it is recommended to reduce the lighting level. With this study, while the risks were revealed, the productivity outputs were also evaluated and it was shown that the Work Study technique could be used in occupational health and safety studies.
