Quantitative Analysis of MRT Rail Construction Industry Workers' Perception of the Human Factor Contributing to Occupational Accidents

Abstract

Occupational accident rates in the construction industry are among the highest compared to other industrial sectors. The human factor plays a major role in contributing to overall occupational accidents in this industry compared to other factors. This study aims to investigate and evaluate aspects of the human factor contributing to occupational accidents in the MRT construction industry. A questionnaire was used for data collection from the MRT construction project around the Klang Valley. Descriptive analysis was used to analyse aspects of the human factor. Mann-Whitney U tests were utilized to compare the perceptions of the management and construction site workers. Pearson correlation tests were used to elaborate on the relationship between all aspects contributing to occupational accidents. Respondents agreed that all aspects studied contribute to occupational accidents except human physical and physiological aspects. The comparison between management and construction site workers indicates no significant difference in their perspectives on human factors. Additionally, the results showed two "moderate" strength relationships: between attitude and dangerous behaviour, and between attitude and competency. This study provides an indepth understanding of safety improvement pertaining to the human factor, and it can guide MRT construction stakeholders to prevent future accidents.
