Comparing the two techniques Tripod Beta and Mort at a critical accident analysis in power plant construction

Accidents are one of the leading causes of death and disability. Despite great efforts made to prevent accidents,\ud there is still no coherent system to identify the root causes of industrial accidents. Selection of appropriate\ud accident analysis techniques and their comparison can be useful in this regard. This research aimed to analyze a\ud fatal accident in a power plant construction project using the two methods of MORT and Tripod-Beta, and the\ud comparison of the analyses. First, the report of the selected accident was studied, and the accident was analyzed\ud by the two methods of MORT and Tripod-Beta. The next step was followed by the comparison and assessment\ud of the methods of MORT and Tripod-Beta with the measures of time, cost, training needs, the need for technical\ud forces, the number of causes identified, quantifiable, and the need for software to conduct analysis. The TripodBeta\ud accident analysis cost less and requires less time, and less technical experts. Thorough analysis of major\ud accidents needs to identify all the possible causes of the incident, including human error and equipment failure.\ud Therefore, the complimentary use of both techniques of industrial accident analysis is recommended
