The oil and gas construction industry has become one of the major high risk industry in Malaysia. With the high volume and cost of project, the risk of safety also become higher. There are significant numbers causes the accident is the human factor. Thus, the requirements of human factor engineering in the process safety management has become compulsory to the industry. However, due to the cost constraints and schedule, management may find way to do shortcut during execution. This study will somehow categorize the human factor engineering causation and portrays its factors that need further research on the subject. The purpose of the case study is to find the factor relate to Human Factor Engineering in Oil and Gas Construction works. The recommendation from the study is to further study the awareness of the Human Factor Engineering implementation in Oil & Gas Construction Works in order to further mitigate the safety risk at projects. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
