Background and Objectives: Accidents prevention and protecting of human capital as the main element in the development of any country is important. This study aimed to use the best available techniques for identifying hazards and assessing risks, in lodge to improve safety, bring down accidents and costs and save time.

 

Materials and Methods: To identify hazards, a documentation review was used, interviews with experts, brainstorming sessions, knowledge and experience group of experts in occupational health and safety engineering were employed. Finally the risks were ranked and compared based on using the degree of Belief approach in Fuzzy logic and Analytical Hierarchy Process methods.

 

 Results: In the present survey, among of the 11 instances of identifying hazards, explosion and fire gas turbines and bust steam pipes under pressure ranked in the first spot and drop down in tanks reservoirs and canals had second place. It was also noted that the effect of the two methods used in this study, are together compatible and consistent.

 

Conclusion: Using the Fuzzy Logic with Multi Criteria Decision Making techniques such as AHP are providing appropriate and complementary approach to identify priorities in the safety control system. In fact, when the decision-makers agree in determining the adjusted data, using these two independent methods will follow the same results in the risk rating.
