Developing Ergonomic Interventions to Reduce Musculoskeletal Disorders in Grocery Distribution Centers

The purpose of this work was to explore intervention concepts aimed at addressing the workers' needs in grocery distribution centers. Worker interviews indicated that many of the items that they handle are heavy, including cases of meat (up to 80 lbs), juice, water, and detergent. Management and safety personnel who participated in a brainstorming focus group session indicated key ergonomic issues include the weight of the meat cases, extended reaching, and even more specifically, overhead reaching. Intervention ideas discussed during the brainstorming indicated a need for mechanisms that reduce reach distances by keeping product close to the order picking aisle and mechanisms that relieve the physical burden of handling heavy product from their storage slots onto the order-picker's pallet jack.
