紧急切断装置是液化气体汽车罐车的重要安全附件,根据《液化气体汽车罐车安全监察规程》的规定,罐体与液相管、气相管接口处必须分别装设一套内置式紧急切断装置。紧急切断装置包括紧急切断阀、远程控制系统和易熔塞自动切断装置,要求动作灵活,性能可靠,便于检修。远程控制系统的关闭操作应装在人员易于到达的位置,易熔塞自动切断装置应设在当环境温度升高时,能自动关闭紧急切断阀的位置。同时紧急切断阀不得兼作它用,以便一旦管道发生大量泄漏时紧急止漏。 相似文献

为研究我国现阶段特别重大事故规律特征,选取2010—2019年的34起特别重大安全事故作为研究对象,利用统计学手段,以这些事故的发生地域、时间、死亡人数、事故分类等因素作为统计标准进行分析。研究发现:从时间角度,我国特别重大事故在近10年整体呈现震荡下降趋势;每年下半年,尤其是8月份为特别重大事故的高发期;特别重大交通事故易发生在夜间与午后,煤矿事故易发生在上午至中午,爆炸事故易发生在上午。针对不同行业或事故类别,交通运输及煤矿行业为特别重大事故的高发行业,爆炸事故为特别重大事故的高发类型且事故后果最为严重。同时,发现同类事故在同地区、同年月、同时段均存在聚集性现象。 相似文献

This study unveils causes of accidents in repair, maintenance, alteration and addition (RMAA) work. RMAA work is playing an increasingly important role in developed societies, including Hong Kong. Safety problems associated with RMAA work in Hong Kong has reached an alarming level. In view of rapid expansion of the RMAA sector and rising proportion of accidents in the construction industry, there is a pressing need to investigate causes of RMAA accidents. Structured interviews were conducted with RMAA contractors to explore causes of accidents in the RMAA sector. A two-round Delphi method with 13 safety experts was subsequently employed to verify the interview findings and rank the relative degree of importance for various causes of accidents. Accidents happen in RMAA work due to intersection of reasons. One of the root causes of accidents in RMAA works is low safety awareness of RMAA workers; however, wider organizational and industrial factors are not negligible. This study sheds light on why accidents happen in the RMAA sector. Only when the factors leading to accidents are identified can effective measures be made. 相似文献

Hydrocarbon (HC) leaks are important initiating events for major accidents in the oil and gas industry. This study explores the extent to which a safety climate indicator from a survey on working conditions undertaken in an oil and gas company (n = 2188) can be used as a leading and/or lagging indicator in relation to HC leaks on 28 offshore installations. It was found that more negative safety climate scores were associated with increasing numbers of HC leaks over a 12-month period following the survey. The safety climate indicator explained more of the variance in HC leaks than technical indicators. HC leaks in the 12-month period preceding the survey did also correlate significantly with the safety climate indicator. More HC leaks during this period were associated with worse scores on the safety climate indicator. Thus, the results support that the safety climate measure could serve as leading and lagging indicator for HC leaks. The results and their possible implications are discussed. 相似文献

There have been several major offshore accidents in different offshore regions since 2005. In Norway there have been several very serious near-misses during the last ten years, several of which involving serious hydrocarbon leaks with catastrophic fire and explosion potential. All these severe occurrences demonstrate the importance of learning from major accident precursors in order to appraise the risk potential involved in critical offshore operations. This paper is based on analysis of about 175 hydrocarbon leaks in the period 2001–2010. Regulatory requirements in Norway are aimed at preventing as far as possible such occurrences during night time, but the analysis shows that this has been far from successful. The industry has for many years claimed that the maintenance personnel are the main group of employees involved in causing these leaks. This study has shown that leaks during the execution of maintenance and modification are less than half of the leaks, and that failures during the preparation for carrying out maintenance tasks are more frequent. Such preparations have often been conducted during night shift. The analysis gives a strong incentive to change this practice. 相似文献
