Analysis of the Body’s Posture and the Risk of Musculoskeletal Disorder in Cleaning Service Workers Working at Height

Abstract

Cleaning service workers' job is the type of job that requires physical strength in carrying out their duties, especially if the work area is at  height, which can cause the risk of Musculoskeletal Disorder. The purpose of this research is to analyze the body’s posture of the workers and provide a recommendation for the level of risk of developing Musculoskeletal Disorder when working at height. This research was conducted using the Rapid Upper Limb Assessment (RULA) method, starting with an analysis of upper body posture including: Upper arm, forearm, wrist and hand rotation, then analyzing the body parts of the trunk and legs. The research results show that the body’s posture while working at height has a score of seven (7), which means it has a high level of Musculoskeletal Disorder risk. The conclusion from this study is that working at specificheight has a high level of Musculoskeletal Disorder risk, and the risk can be reduced by providing ergonomics assistive devices.
