Abstract
|
|
|
Job hazard analyses were conducted to assess exposure to musculoskeletal disorder (MSD) risk factors in seven workers of three dry-cleaning establishments. In accordance with the Washington State Ergonomics Rule, the analyses were performed in two separate steps: (1) observation and checklist approaches were made to identify a ¡°caution zone job¡± in the seven workers' pressing operations across the three shops; and (2) detailed posture and motion analyses were undertaken to determine a ¡°MSD hazard¡± in one worker's operation using a video technique. One ¡°caution zone job¡± was identified and it was the pressing operation job in which five physical risk factors were found in the pressing operations. The detailed analyses confirmed that one ¡°MSD hazard¡±, i.e., awkward posture in shoulders, was prevalent in the pressing operations of the three dry-cleaning facilities. It would be desirable to reduce MSD risk factors including awkward shoulder posture in the dry-cleaning industry.
