The goal of this study was to apply ergonomic controls in the soft drink beverage delivery industry, and measure the effectiveness in reducing musculoskeletal injuries through psychophysical, physiological, and biomechanical methods. Nine driver/sales workers with an average of 20 years experience participated in the study. Risk factors inherent in the job included exposure to whole body vibration from driving the trucks, pushing and pulling loads exceeding 350 pounds, repetitive lifting and moving of crates, slip and fall injuries, surface conditions, exposure to sharp glass from broken glass bottles, robberies, and moving products from bays into the trucks. All nine participants reported suffering a work related musculoskeletal injury, with eight reporting back injuries, five reporting arm injuries, and four reporting leg injuries. All had taken time off as a result of the injuries, with the average time off being 2.8 months. The author recommends the use of several engineering controls, including drop down shelves; low boy tractor trailers; redesigned grab handles; antislip grit on bay rails, platforms, foot wells, and steps; additional foot wells; pullout steps; a dual hand truck holder with high back; adjustable height air cushioned seats; bay door straps; and relocation of the computerized beverage billing and printing system within the truck.
