Data of accidents causation of 39 HCAs investigation reports

The data were collected to help confirm the probability matrix of the Bayesian network for human factor analysis and classification system(HFACs). The data file shows 39 hazardous chemical accidents in China, and the accidents causation of these accidents. The first six colums is the code of accidents, accident unit, accident area, accident date, accident type, and death toll of accidents, respectively. The residual columns are accident causation classifacations according to HFACs, in which 1 represents this reason exists, null represents this reson not exists. 29 accidents resports were collected from the official website of China Chemical Safety Association (http://www.chemicalsafety.org.cn/) and 10 were from the website of Baidu. Based on these data, the Bayesian network for HFACs was constructed, and the sensitivity of each node could be calculated. The results shown that human factor is the direct cause of operating errors, while hazardous material environment, mechanical equipment, and human factors are direct causes of operation violation. There is also the indirect cause of human unsafe behavior, they are the effects of organization climate, hidden danger investigation, organizational process on operation errors, and the effects of resource management, operation guidance, planned operation on operation violation. And compared with other factors, the sensitivity of organization climate is most obvious.
