In response to a request from the United Food and Commercial Workers Union in Clifton, New Jersey, NIOSH conducted an evaluation of possible hazardous working conditions at the Shoprite Supermarkets (SIC-5411) located in New Jersey and New York. The nature of the problem involved cumulative trauma disorders (CTDS) among employees serving as checkers. CTDS occurred in workers whose jobs required repetitive exertion, most often of the upper extremities. Multiple logistic regression (MLR) analysis revealed elevated odds ratios for checkers compared to noncheckers for all parts of the upper extremities. However, only the associations for shoulder and hand were statistically significant. MLR analysis of the checkers alone revealed a statistically significant dose response relationship between checking and disorders for all parts of the upper extremities. Differences were also noted between prevalences of disorders in those using different checkstand designs. The ergonomic analysis examined repetitiveness, posture and efficiency of movements for the different checkstand designs. The total repetitions per hour based on normal customer orders ranged from 1432 to 1782 for the right hand and 832 to 1260 for the left hand. Multiple awkward postures were detected involving all parts of the upper extremities. Recommendations were made for ergonomically improving checkstand design as well as temporarily altering the existing checkstand designs.
