Study On The Gasaccident Risk Perception Of Urban Residents

With the rapid development of gas in recent years,tens of thousands of households have employed it,but gas accidents have suffered a great increase by years.So it is necessary for gas consumers to analyze the structure of the accident risk.Based on the management of gas users and the analysis of the accident risk,this thesis builds up the cognitive model of urban residents 'accident risk through the relevant theory of risk cognition and discusses the influencingfactors of the cognition of residents' accident risk and the relationship between operation behavior and coping behavior to provide ideas for safety management of gas users.The accidental fire,poisoning and suffocation are analyzed.Accordingly,35 basic events are obtained and minimum path set is calculated.In addition,the 16 means of controllingthe accident are got so as to provide the measuring object for the empirical risk cognition of the gas user.Combining with the theory of risk perceptionand related research,this paper clarifies the concept,influencing factors,the operation of risk perception measurement,the operative behavior of residents and theirrisk responses of urban gas users and constructs the risk perception model which centers on the level of risk cognition,regards influencing factors as input variables,operative behavior and coping behavior as output variables.This thesis conducts an empirical study onstructural model of constructed risk cognition theory by means of questionnaire which includesinfluencing factors of risk perception,risk perception level,operative behavior and coping behavior.The influencing factors of risk perception are composed of seven aspects such as individualfeature,gas used experience,risk characteristics,risk attitude and responsibility awareness,communication of risk information,corporate trust,education and training of gas safety.It also analyzes the mean value,otherness and correlation of data obtained in virtue of SAS.
