Safety of Workers When Dealing with Machinery in Construction Project

Abstract

Construction projects range from minor repairs to large-scale infrastructure developments and rely heavily on the handling of construction machinery, including excavators, bulldozers, cranes, loaders, and dump trucks. These machines increase efficiency, reduce manual labor, and ensure precise outcomes. However, the risks associated with construction activities necessitate stringent safety measures, underscored by the Occupational Safety and Health Act of 1994, enforced by the Department of Occupational Safety and Health (DOSH) to prioritize worker safety. This paper aims to identify the types of injuries resulting from machinery use, analyze current safety practices, and propose strategies for enhancing worker safety. Key findings reveal that cuts and lacerations are the most frequent injuries, while crushing injuries rank lowest. Furthermore, current safety measures emphasize the importance of providing appropriate personal protective equipment (PPE) for workers. The study highlights the need for clear safety protocols, signage, and designated safety zones to improve machinery handling, with training programs identified as a lower priority for enhancement. Data were gathered through a questionnaire survey distributed to construction personnel which is 28 respondents from G7 contractors in Shah Alam Selangor, including engineers and supervisors, and analyzed using the relative importance index and reliability analysis. The findings are intended to assist construction companies in addressing safety concerns and offer valuable insights for industry personnel and policymakers focused on improving safety practices in construction projects.
