D7-2　Ergonomic Assessment of the Working Conditions of Checkout Counter Cashiers in a Grocery Store in the Philippines

Abstract

In most grocery stores in the Philippines, the checkout counter cashiers are standing throughout their shift. They are also subjected to repetitive tasks and awkward postures. This study aims to investigate the working conditions of the cashiers in one of the groceries in the country. In particular, the perceived pain of each worker was determined using Cornell University Musculoskeletal Discomfort Questionnaire (CMDQ). Rapid Entire Body Assessment (REBA) was conducted to evaluate their postures and identify the level of risk of developing musculoskeletal disorders (MSD). The perceived pain and the risk level were then tested for correlation using Spearman’s rho; however, it was found out that no significant correlation exists. Furthermore, relevant workstation measurements were gathered and compared against the anthropometric measurements of the cashiers. Results showed that much can be done on their workstation to improve man-machine interaction and to mitigate the risks of MSD.
