2019—2022年餐饮燃气事故统计与分析

Statistics and Regularity Analysisof Catering Gas Accidentsfrom 2019 to 2022

从事故发生区域、月份、日期、时间段、类型、气源、诱因等方面,系统全面分析2019—2022年餐饮燃气事故,建立事故相对严重程度分析模型,进行事故信息图形化展示。2019—2022年全国发生餐饮燃气事故共251起,造成75人死亡,523人受伤。一般事故频发,较大及以上事故时有发生,燃气安全形势依然严峻。餐饮燃气事故涉及的26个省、直辖市、自治区中,广东、安徽、山东、浙江、江苏的事故数量较多,通过事故相对严重程度分析得知,吉林、辽宁、河北、山东、江苏和浙江等区域需特别重点关注,事故防范任务艰巨。12个月中,7月发生事故最多,11—12月、1—2月较少;一个月31 d中,月中事故数量远远高于月初和月末;一日的24 h中,6:31—9:30发生事故最多,0:31—3:30发生事故最少。针对事故类型,爆炸事故数量和死亡人数最多,应成为餐饮燃气事故控制的关键点。从事故气源看,液化石油气事故占97.44%,管道天然气事故占2.56%,对于使用液化石油气的餐饮用户应重点关注。为进一步有效防范餐饮燃气事故,应落实燃气入户安检责任,要求餐饮用户合规使用燃气。

The catering gas accidents from 2019 to 2022 are systematically and comprehensively analyzed in terms of the accident area,month,date,time period,type,gas source,and cause.A model for analyzing 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 occurred 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 province,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 needed special attention,and the task of accident prevention was arduous.Within 12 months,the most accidents occurred in July,and fewer occurred in November-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 beginning 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 petroleum gas accidents accounted for 97.44%,and pipeline natural gas accidents accounted for 2.56%,and catering users using liquefied petroleum gas should be focused on.In order to further effectively prevent catering gas accidents,the responsibility for gas household security checks should be implemented,and catering users should be required to use gas in compliance.
