Abstract. The construction sector is among the most hazardous industry due to the working environment which exposes workers to high risk of accidents. Statistics by the Malaysian Ministry of Human Resource had shown that the number of mortality and disability cases involving construction workers were the highest among the other sectors. Most of the cases were caused by unidentified hazards around the construction sites. The literature had documented that environmental factors were responsible for most of the cases. This paper aims to highlight on the causation factors of accidents and injuries at the construction sites based on the human factor. Selected journals and research papers related with accidents at construction sites were reviewed and human error was found to be the main causation factor of accidents at construction sites. This study urges for more in depth study on the actions or interventions that could be taken to minimize the occurrence of human error in the construction site, thus, minimizing the occurrence of accidents, injuries and even mortality.
