The effects of container design and stair climbing on maximal acceptable lift weight, wrist posture, psychophysical, and physiological responses in wafer-handling tasks.

摘要: Despite the high level of automation in semiconductor manufacturing processes, many manual operations are still involved workplace. Due to inadequate human-machine interface design, stairs frequently used help operators perform wafer-handling tasks. This study was designed evaluate effects climbing and carrying wafer containers (pods) on psychophysical responses (maximal acceptable weight lift--MAWL, ratings perceived exertion--RPE), physiological (oxygen consumption--VO2, heart rate--HR), wrist posture (ulnar radial deviations). Each 12 subjects (six males six females) performed sessions (3 x 2 pods types). The results indicate that had a significant influence MAWL VO2 (p<0.01). type pod effect Gender differences MAWL, were also (p<0.05). Job design implications discussed.
