Statistics and Regularity Analysis of Catering Gas Accidents from 2019 to 2022
The catering gas accidents from 2019 to 2022 are systematically and comprehensively ana-lyzed in terms of the accident area,month,date,time period,type,gas source,and cause.A model for analy-zing the relative severity of accidents is established,and the accident information is displayed in a graphical manner.From 2019 to 2022,there were a total of 251 incidents of catering gas accidents in China,resulting in 75 deaths and 523 injuries.Ordinary accidents oc-curred frequently,larger and above accidents occurred from time to time,and the gas safety situation remained severe.Among the 26 provinces,municipalities and autonomous regions involved in catering gas accidents,Guangdong province,Anhui province,Shandong prov-ince,Zhejiang province and Jiangsu province had a higher number of accidents.Through the analysis of the relative severity of accidents,it was found that Jilin province,Liaoning province,Hebei province,Shandong province,Jiangsu province and Zhejiang province nee-ded special attention,and the task of accident preven-tion was arduous.Within 12 months,the most acci-dents occurred in July,and fewer occurred in Novem-ber-December and January-February.Among the 31 days of a month,the number of accidents in the middle of the month was much higher than that at the begin-ning and end of the month.Among the 24 hours of a day,the most accidents occurred from 6:31 to 9:30,and the least accidents occurred from 0:31 to 3:30.Regarding the types of accidents,the maximum number of explosion accidents and deaths should be the key points for controlling catering gas accidents.From the point of view of accident gas source,liquefied petrole-um gas accidents accounted for 97.44％,and pipeline natural gas accidents accounted for 2.56％,and cate-ring users using liquefied petroleum gas should be fo-cused on.In order to further effectively prevent cate-ring gas accidents,the responsibility for gas.household security checks should be implemented,and catering users should be required to use gas in compliance.
