Design and Application of Risk Evaluation Index System for the Safety of Household Gas Appliances Based on AHP-Fuzzy Model.

ABSTRACT: With China's emphasis on and promotion of gas development, gas has become one of the indispensable energy sources in people's lives. The study found that there are still some gaps in the safety risk field of household gas appliances. This paper proposes the design of a risk evaluation index system for the safety of household gas appliances. Through the safety checklist of an indoor gas system, the direct causes of indoor gas accidents are analyzed and converted into risk factors. Using the analytic hierarchy process, the risk types are divided into household gas equipment risk, gas equipment accessory risk, and personnel operation risk. These are set as the first-level indices of the evaluation system. Subsequently, 12 risk factors are divided into the second-level risk evaluation indices,
