A New Framework for Exploration of Transportation Maintenance-Related Prevalent Work Injuries, Hazardous Activities, and Effectiveness of Ergonomic Solutions in the United States
Author/Presenter: Guo, Xingzhou; Chen, Yunfeng; Zhang, Jiansong; Hubbard, BryanAbstract:
The transportation industry involves various ergonomic injuries caused by activities exceeding workers’ capabilities. Although the construction industry has been thoroughly studied regarding work-related injuries, hazardous activities, and effective ergonomic solutions, there is a lack of such research in the transportation sector. However, injuries, risky activities, and effectiveness of solutions may be different in transportation activities due to different work duration, intensity, and frequency. Thus, this research intends to explore the common work-related injuries, hazardous transportation activities, and the effectiveness of ergonomic solutions for transportation maintenance workers. This thorough examination incorporated historical injury records, online surveys, in-person site observations, and field experiments. Specifically, a preliminary list was first created based on transportation workers’ historical injury data, including common injured worker positions, injury types, activities causing most injures, and potential risk factors. An online survey was then designed to identify work-related injuries and activities. Following observations, field experiments involved 29 transportation maintenance workers. Back injuries emerged as the most prevalent when engaging in lifting and pushing/pulling tasks. Using a back exoskeleton can eliminate physical fatigue risks when lifting weights of 50 pounds or more. In addition, lifting lighter loads (31.5 pounds) can significantly reduce the risk of injuries.
