Identification of Workplace Risks and Their Risk Assessment During Transmission Line Construction: A Case Study on Infrastructure Project in Nepal

Abstract

AbstractThe research was intended to, identify the possible hazards, preventive and control measures implemented and assess their effectiveness at work place. Kaligandaki Transmission corridor project was selected for the study. The Kaligandaki transmission corridor projects extend from Mygdi to Nawolparasi with construction of three substations at Dana, Kushma and Nawolparasi. The research was carried out by utilizing the data collected from the experience and knowledge of KII experts, local people and researchers field observations along with by asking the duly semi structured questionnaire with client, consultant, contractor's managers, officers, engineers and the workers. It was identified that mechanical and fall hazards were the most prevailing hazards during construction. Exposures hazards, biological hazards, chemical hazards and psychological hazards were also found at work place. The major cause of accidents was the lack of knowledge and skill along with carelessness of the workers. Other activities like scaffolding works, deep excavation, material transportation, lifting and assembling of towers parts were also found as the equally risky activities during the construction of transmission line. It was responded that the major health problem faced by the workers due to physical hazards was the back pain and wrist pain. Similarly due to chemical hazards most of the workers responded allergic as the main health problem they faced during construction. So the management commitment towards motivation, health and safety along with workers participation are essential for the success of the project. Prevention and control measures have to be plan as per the level of risk.KeywordsConstruction transmission lineSafety managementWorkersRisk
