The energy source based job safety analysis and application in the project

The hazard identification is one of the most significant issues of the safety management process. Conventional approaches to hazard identification in a job safety analysis (JSA) tend to failure of identifying all the potential hazards involved in a work and can lead to accidents. How to identify the hazards thoroughly has becoming a challenge. The energy source based job safety analysis (ESBJSA) method proposed in this paper, aimed to identify and assess all the potential hazards effectively by applying an analysis basis on energy sources. Through clarifying the energy sources in each sub step and identifying the corresponding potential hazards of each energy source respectively, the measures and solutions to eliminate or reduce the risks can be determined. The ESBJSA method was applied in an offshore construction and installation project, and the total recordable incident rate (TRW) result was reduced 50% when compared with another similar project using conventional JSA method. Additionally, ESBJSA is a technique that can be fully applicable to many high risk construction and installation projects in shipyard. (C) 2016 Elsevier Ltd. All rights reserved.
