Empirical study of manual performance in outdoor workers during extreme cold air exposure

Human exposure to cold air is a major hazard in outdoor work in many parts of the world, in particular during the winter season.This study aimed to analyses the effect size of exposure to extreme cold on manual performance. The study population consists ofoutdoor auto mechanic workers which are participated for two steps in winter and spring seasons. Air environmental factors 50included dry-bulb temperature and air velocities were measured in the workstation of each subject. Body physiological responsesTouch sensory tests were conducted for determining.9886 were also measured during daily activities in accordance with ISOhands sensorineural functions. The grip and pinch strength and manual dexterity tests were also conducted for diagnosis of workdisability. The results showed there is a significant difference between body physiological responses of workers in winter andto%18 It is revealed that the work abilities of the outdoor workers in winter have been decreased from.)0.01
