玻璃痕迹物证在火灾中的证明作用

火灾发生以后,建筑物内的可燃物都已变成残骸。大量生活用品燃烧殆尽,物理形态发生了根本性的变化。玻璃有着独特的属性,在火灾现场能够保留下来。因此,勘验火场以辨识玻璃痕迹为主要工作内容。玻璃痕迹,成为了证实火灾发生原因的重要物证。     

Accountability for performance in English and Scottish fire and rescue services from 2010 to 2016

ABSTRACT

Using evidence from English and Scottish fire and rescue services from 2010 to 2016, this paper shows how divergent performance management regimes can affect public accountability. Performance management regimes enable agencies and the public to hold public sector organizations accountable by facilitating evaluation of their accomplishments. However, local as opposed to central, control over performance management can have quite different implications for public accountability.     

我国股票市场是否存在资产被迫拍卖——基于开放式股票型基金的研究

对于资产被迫拍卖行为的研究具有重要意义,因为它为我们提供了一个新的视角探讨流动性约束对股票价格变动的影响。本文基于Coval和Stafford(2007)的研究方法对我国股票市场中资产被迫拍卖行为的存在性进行了研究,结果表明在我国股票市场中存在着资产被迫拍卖行为,但其具体表现特征与Coval和Stafford(2007)的研究结论存在着一定的差异,而导致该差异出现的原因与我国开放式基金市场中存在着赎回困惑现象有关。     

Owning and testing smoke alarms: findings from a qualitative study

Reducing injury and death in house fires is an important public health intervention activity with the presence of an operating smoke alarm widely considered an important way of reducing harm from fire. Yet despite a number of initiatives and fire-safety campaigns, a number of households at greater risk of domestic fire fail to have a functioning alarm. This paper provides empirical insight into everyday experiences of owning, maintaining and testing smoke alarms among a purposive sample of individuals identified as being less likely to own a functioning smoke alarm. Analysis from focus group data identifies a number of reasons why individuals may not own or test an alarm, and provides new insight into how fire risk is understood in the context of a range of competing, and potentially more prominent, individual and household risks. We suggest that while initiatives that aim to reduce fire injury and death should be continued, their success, and indeed future research on fire risk, should pay attention to the mundane and everyday contexts within which individuals currently rarely reflect on their risk of experiencing a domestic fire.     

二氧化碳三相泡沫防灭火技术在综放工作面的应用

矿井火灾是煤矿主要灾害之一,严重影响了煤矿安全生产。为了使煤矿安全、高产、高效,结合易燃超厚综采放顶工作面开采特点,通过对二氧化碳物理、化学性质以及惰化,吸附能力等方面进行分析,对比二氧化碳与氮气的灭火特点,研究了利用二氧化碳代替氮气的三相泡沫防灭火新技术,并对二氧化碳三相泡沫的组成、发泡原理、特点、灌浆工艺等内容进行介绍,已将二氧化碳三相泡沫应用于矿井火灾的防治,取得了良好的技术效果和经济效益,为矿井的安全生产起到关键性作用。     

Experience and the unexpected: risk and mitigation issues for operating underground storage silos for coal-fired power plant

Observed autoignition events and extinguishing the resulting smouldering fires in an underground storage system of a coal-fired power plant have provided insight into the array of contributing variables, and some experience on quantifying the risk with alternative scenarios of event initiation, progress and potential mitigation. Although the first attempts to quantify the risk suggest high sensitivity to the sequence of action taken after fire alarm, and no similar storage sites really exist, some recommended preventive, corrective and other mitigating activities can be at least partly defined and improved by using the cumulative experience and parallel efforts in other closed or underground storage sites. However, there are also so-called black (or at least grey) swans: unexpected events for which the facility may be poorly prepared for. In the case of the underground storage silos, such an event was experienced when incoming cold coal during a harsh winter season froze the sewer system that normally protects the stored coal from seepage water. With blocked normal bypass, the seepage water found its way to the coal silos and created large clumps of icy coal that blocked the coal conveyors. Although freezing weather is not unusual at high-latitude power plants, the common methods to combat freezing of coal are mainly useful for open storage sites and above-ground transport. Options for mitigation are discussed, as well as the event chain leading to an event that had never previously occurred. The case is discussed from the point of view of options to prepare for rare or unforeseen events.

航站楼火灾场景下的人员疏散仿真研究

机场航站楼结构复杂,发生火灾时极易对人员的生命财产安全造成威胁。为直观了解航站楼中不同位置发生火灾时产生的烟雾对人员疏散的影响,建立航站楼到达厅与夹层通道的火灾模型与人员疏散模型,分析3种不同火源情况下各关键位置烟气的温度、CO浓度和减光系数与疏散情况。结果表明,行李转盘区与夹层通道发生火灾时烟气会弥漫整个夹层通道,影响疏散安全。在航站楼现有建筑结构下,到达口联动开启可有效缩短人员疏散时间。     

论消防部队信息化建设的途径

近几年，我国消防行业的信息化建设有了长足的发展，各地都新建或改造了消防通信指挥系统，开发应用了一批消防信息管理软件，建起了许多消防专业网站，开始实施电子政务，消防信息网络初步形成。总体上看，我国消防行业的信息化水平与美国、日本和西欧等发达国家相比，由于起步较晚，加之综合实力、基础研究较弱，我们的差距还很大。本文首先介绍了消防发展的趋势，接着分析了消防部队信息化建设的现状，最后提出了消防部队信息化建设的方向和基本途径。
