可移动充气式应急救护装置的研究

可移动充气式应急救护装置是一种重点针对地铁火灾的新型消防抢险救援装备,主要由风机、风管、救护站及其他辅助设备组成,其工作原理是采用机械通风的方式在救护站内建立正压,阻止外界烟气进入,从而在充满烟气的事故现场建立一个没有烟气的临时安全场所。可用于救助受困人员,方便消防员更换装备和休息调整,以及便于消防部队建立前沿临时指挥点等,为消防部队处置地铁火灾提供了解决问题的新思路和新方法,对提高消防部队在地铁火灾中的抢险救援能力有着重要的作用。除此之外,还可用于其它类型的地下建筑、大空间建筑(如商场)等场所的消防抢险救援。     

基于SDSL传输技术的煤矿多媒体救灾系统研究

介绍一种新型的SDSL(对称性数字用户环路)数据传输技术,该技术采用对称数字用户线点对点宽带传输数字信号,在利用一对电话线进行双向对称数字信号传输时,最大传输速率可达到1.5Mb/s。应用SDSL传输技术研制出煤矿多媒体救灾系统,详细阐述煤矿多媒体救灾系统的构成、功能及特点等,该系统能够实现井下灾区多媒体信息的实时传输,解决在矿山救灾的特殊环境条件下实现灾区图像\语音实时传输到井下救援基地、地面指挥中心及国家矿山救援指挥中心的难题。     

北京、东京及釜山地铁防灾应急设施现状调查研究

地铁在面对各种灾害时,各类防灾及应急设施的准备是否充分将直接影响到救援工作的质量。通过实地考察北京、日本(东京地铁车站为主)及韩国釜山城市的地铁车站防灾应急设施,探讨东京和釜山地铁与北京地铁应急设施的异同,并结合我国关于大型现代地铁枢纽站应急预案的研究,针对我国地铁在防灾应急设施方面存在的问题提出改进建议。     

高速公路紧急事件处置现场视频无线传输系统的研究

从高速公路交通事故紧急处置和应急救援的角度出发,在对高速公路交通事故过程、影响因素、紧急处置与救援特点及其信息需求分析的基础上,指出高速公路现有的有线监控系统、CDMA,GPRS系统均无法满足高速公路交通事故紧急处置和应急救援中对视频实时传输的需要。给出了笔者研发的适用于高速公路应急救援现场的基于WLAN的无线视频实时传输系统的基本原理与功能。     

店员在超市安全疏散中的作用研究

对某超市安全疏散演习资料进行分析,研究超市店员在火灾疏散中的行为对顾客的影响。通过观看疏散录像,分析疏散之后所作的问卷调查,采用SPSS统计分析软件分析不同位置店员在听到火灾警报后的反应。研究发现:店员的疏散前准备时间随他们所处的位置而不同,也因在不同岗位的店员所承担的责任不同。由于经过消防训练和对环境比较熟悉,店员的疏散速度明显快于顾客的疏散速度。在整个疏散过程中,大约80%的店员为顾客安全疏散提供帮助,对顾客及时撤离产生直接的有益影响。一些骨干型的店员在疏散中发挥了重要作用。对商店消防培训和疏散预案的制定提出建议。应根据店员岗位设置不同培训内容,并注重培训骨干消防员;对店员行为进行干预;制定性能化的疏散预案等。     

煤矿突发事件应急救援的群决策方法

提出了基于直觉模糊集的煤矿突发事件应急救援TOPSIS群决策模型。其中决策者权重采用偏好值与群体平均偏好值的相似度计算,属性指标权重采用直觉模糊熵权法确定。通过直觉模糊加权集成运算将各决策矩阵进行合成得到综合决策矩阵,利用改进后的直觉模糊距离公式计算出全部备选救援方案到正负理想解的距离,根据TOPSIS运算结果可以确定最佳事故救援决策方案。最后通过黑龙江省鸡西某矿的实例分析,验证了该模型的有效性及合理性。     

Simulation of scenario characteristics of LPG tank explosion accident and its contribution to emergency planning: A case study

Leakage and explosion of hazardous chemicals during road transportation can cause serious building damage and casualties, and adoption of highly-efficient emergency rescue measures plays a critical role in reducing accidental hazards. Considering a liquefied petroleum gas (LPG) transport tanker explosion accident that occurred in Wenling, Zhejiang Province, China on June 13, 2020 as example, this study proposes a risk assessment framework. This framework recreates the leakage and explosion of the accident process using FLACS v10.9, suggests plans for evacuation, describes the rescue areas of different levels, and explores the influence of environmental factors on the evacuation and rescue areas. The results show that simulated and predicted distributions of fuel vapour cloud concentration and explosion overpressure can provide a reference basis for rapid rescue activities; the characterization of the dynamic effects of wind speed, wind direction, and temperature with respect to the evacuation and rescue areas can be used as theoretical support for on-site adjustment of rescue forces. The role of obstacles can prevent the expansion of the evacuation areas under low wind-speed conditions, and the presence of highly congested obstacles determines the level of the rescue area. The results obtained are important for the risk analysis and the development of emergency rescue measures in case of explosion accidents associated with transportation of hazardous chemicals on high-hazard and high-sensitive road sections.     

‘Sea of blood’: the intended and unintended effects of criminalising humanitarian volunteers assisting migrants in distress at sea

This paper investigates the impact of the recent criminalisation of humanitarian actors engaged in the search for and rescue of migrants in distress in the Mediterranean Sea, focusing on the impact on the motivation and engagement of humanitarian volunteers in Greece. It argues that criminalisation is aimed at reducing search and rescue (SAR) activities and thus removing perceived ‘pull factors’ for migrants. The paper locates this phenomenon within the broader trend of policing and punishing those who assist migrants in order to deter them and prevent others from engaging in such endeavours. It finds that efforts to criminalise can have the unintended effects of encouraging and mobilising volunteers, as well as generating public attention and support for migrants. However, the negative consequences of criminalisation are far-reaching, including contributing to a high mortality rate among those crossing the Mediterranean without SAR capabilities and the heightened risk of violence against migrants and those who help them.     

辅助矿山救护队的建设工作应该加强

在现代煤矿里，灾害和事故仍然是不可避免的。采取减小组织内成员的自由度来强化专业救灾机构的整体功能固然重要，但非专业化的辅助矿山救护队的建设工作更应加强。因为他们亲临现场，熟悉灾情，又处于救灾的黄金时间里。因此，对是否酿成灾害和灾害中损失的控制问题，辅助矿山救护队有更多的优势。
