Musculoskeletal Discomfort Evaluation using Quick Exposure Check (QEC) among Tower Crane Operators

Abstract

Abstract Tower crane operators are at risk of developing Musculoskeletal Disorders (MSD) due to work schedules that require prolonged sitting with minimal movements. The aim of this study was to assess the discomfort levels associated with the musculoskeletal disorder and its severity on affected human body areas of tower crane operators while driving and handling of materials. This study was conducted amongst 32 tower crane operators at the construction sites of a high-rise building in Klang Valley. A Quick Exposure Check (QEC) was used to assess the MSDs levels and the affected severity on human body areas. The results from the QEC showed the body parts that were associated with a very high risk of MSDs were the back and neck. Other factors contributed to the high risk of MSDs among tower crane operators were identified as driving and vibration. MSDs among tower crane operators were evident from the QEC analysis. Therefore, it is essential to include ergonomic intervention in the workplace in order to minimize the risk.
