Risk assessment through heart rate of a team of airport workers loading Unit Load Devices

Abstract

Literature shows that musculoskeletal disorders (MSDs) are common among airport baggage handlers, but Unit load Device (ULD) loading/unloading has not been examined before. In this paper we recorded heart rates of six workers handling 12 ULDs each up to 1,000 kg. The workplace precludes the use of ISO 11228-2 standard because the tasks of loading/unloading are performed by a team of workers with no wheeled equipment on a slope surface. Besides, no single method in literature contemplates the assessment of braking tasks in the unloading stage. Both loading and unloading tasks showed low physical effort despite the heavy handled loads. Improvements could include ergonomic handles and better Aircraft Cargo Loader operation to minimize manual handling. Though limited by sample size and reliance on heart rate, the results suggest that heart rate could be a valuable parameter for assessing workers’ effort in non-standardized work environments where other risk assessments tools are non appliable. These findings can help enhance workplace safety and reduce MSD risks in air cargo operations. The adoption of these measures may also decrease aircraft loading times. The improvements could result in greater slot availability at the airport and subsequently enhance overall airport profitability.
