Cause analysis of fire door safety hazard based on the method of fishbone analysis and analytic hierarchy process
The fire door can effectively block and contain the rapid spread of fire in the event of a fire,and at the same time increases the fire rescue time to ensure the safety evacuation of people.In this paper,the causes of the safety hazard of building fire door was taken as the research object,and the cause-type fishbone diagram method is used to analyze the 4 main causative factors and 14 sub-factors,then the analytic hierarchy process(AHP)was used to quantify the related causative factors,and the weight of each contributing factor was determined through the calculation of judgment matrix and consistency test.Based on the weight value of causative factor of fire doors safety,the main factors causing the fire door safety hazard was found out and relevant suggestions were put forward.The results show that:among the 4 main factors which affect the safety performance of fire doors,the production factor has the highest weight value,and it has the greatest influence on safety performance of the fire door;while among the 14 causative factor of the secondary index,the prevention and control emphasis should be placed on the material quality and fire performance of fire door,the manufacture and installation deviation of fire door size,the design and selection standardization of the fire door.
