Safety culture assessment of petroleum enterprises based on SMART

This paper introduces an improved fuzzy comprehensive evaluation model specially designed for the safety culture assessment of petroleum enterprises. The model is established based on the authors’ years of experience in this field. The index system of the safety assessment mentioned herein is based on SMART safety culture principles, covering safety material, safety behavior, safety system, safety belief, persistence of safety, and openness of safety. The proposed system also includes the safety material culture, in which on-the-spot analysis of the key factors of safety culture is conducted together with duty consultants. All the fuzzy membership indexes and their degrees were weighed and calculated with the final evaluation results, presented in accordance with the analytic hierarchy process. All the safety culture statuses of petroleum enterprises Z, S, and C were then incorporated into detailed analysis. The results of the application confirm that the levels of safety culture follow the order of Z petroleum enterprise <S petroleum enterprise <C petroleum enterprise. The safety culture grades of the S and C petroleum enterprises are "qualified," and it indicates that production can proceed. By contrast, the assessment result for Z petroleum enterprise is "not qualified", and it means that its production has to be prohibited. These results show that the fuzzy comprehensive evaluation model is suitable for evaluating the degree of safety of the studied petroleum enterprises. The reward and safety material culture, as well as safety conditions and safety reliability, should be taken as the key factors in safety culture construction for petroleum enterprises. Thus, the proposed model heightens production levels, and plays an important role in the construction of business safety culture.
