4.当离开房间发现起火部位就在本楼层时,应尽快就近跑向已知的紧急疏散出口,遇有防火门应该及时关上,如果楼道被烟气封锁或者包围的时候应该尽量降低身体尤其是头部的高度,用湿毛巾或者衣物捂住口鼻。

  活动过程中,孩子们充分发挥想象力,有的消防员拿水枪救火、消防员手提灭火器、遇到火灾如何逃生……一幅幅构思新颖、主题鲜明的绘画作品充分展现了小朋友们对消防的关注和认识,让孩子们以寓教于乐的形式提高了消防安全意识,起到了良好的宣传效果。

  5人于10月4日上午10时结伴到萧山区瓜沥镇航坞山游玩,出于好玩目的,在消防英雄铜像上进行踩踏和蹲坐并拍照留念。虽然消防救援不可能没危险,但我们可以通过打造科学的应急救援体系而让消防人员尽量少流血。

  近日,北京丰台消防支队集中对辖区医疗场所前期发现的火灾隐患进行隐患回查检查,采取“回头看”的方式确保火灾隐患不抬头。

  期间,北京消防140余个消防中队全部对外开放,开展消防宣传“请进来”活动,组织300余所学校近7000余名学生到中队体验火灾报警装置、烟雾逃生帐篷、火灾扑救演示等,学习消防安全常识。督促餐饮场所、单位食堂提高油烟管道清洗频次,餐饮场所集烟罩和烟道入口处1米范围内,应当每日进行清洗,排油烟管道每60日至少清洗1次。

  因此,液化气钢瓶严禁在太阳底下暴晒。

  此地一为别,不是孤蓬万里,而是千帆竞发,百舸争流天寒心暖,纸短情长。

  在实地参观兰陵国家农业公园、金兰物流园等地时,亲眼看到、亲手触摸了处于改革开放中的绿色临沂,也在规划馆展望了明天更上一层楼的临沂。  在公开道歉后,四人再次到瓜沥航坞山消防英雄铜像前,向烈士鞠躬致敬,再次表达歉意。

【媒库文选】城市屋顶的崛起

2018-11-15 12:01:02 来源:参考消息网 责任编辑:李赛
去年9月30日下午,柳州市消防支队作战指挥中心电话声骤然响起,同时打进数十个排队电话,称柳城县范围内多处连续发生爆炸。

核心提示:在越来越多高密度的城市中,其中一部分屋顶用于娱乐——从酒吧和泳池到足球场和跑道的各种东西如今在摩天大楼楼顶上都能找到。但是,如果屋顶能晒到太阳,那它就有另外两个更明显的用途——农业和太阳能。

The Rise of the Urban Rooftop

城市屋顶的崛起

Laurie Winkless 劳里·温克利斯

Our cities have never been denser, taller, or busier than they are now, and with that, comes the constant battle for land. Whether you're a city dweller, developer, transport planner, or farmer, you're forced to compete for dwindling amounts of available space. And with two-thirds of the world's population predicted to live in cities by 2050, the stress on urban infrastructure looks set to outpace even the most carefully-laid plans. But if we look at aerial images of any city center, we can quickly spot plenty of unused space - the rooftops.

So what can we use this precious resource for? In a growing number of high-density cities, some of it is dedicated to recreation - everything from bars and pools, to soccer pitches and running tracks can now be found atop skyscrapers. But when a rooftop offers access to sunlight, there are two more obvious candidates for its use - agriculture and solar power.

Green roofs have been growing in popularity for more than a decade, and in some cases, growing in scale too - atop a convention center in Manhattan sits the city's largest, covering an area of 89,000 m2. Usually comprised of planted beds, or carpet-like tiles that encouraged the growth of low profile vegetation, green roofs can provide a habitat for birds and insects in an otherwise hostile environment. They also act as thermal insulation for the building, and reduce storm water runoff that can otherwise cause havoc in urban sewers.

Green roofs come with the added benefit of mitigating the dreaded urban heat island effect, whereby, as a result of heat-absorbing materials like asphalt and concrete, cities can be several degrees warmer than the surrounding countryside. In contrast, trees and green spaces can absorb shortwave radiation, and use it to evaporate water from their leaves - a kind of 'double cooling' effect.

As food security and urban nutrition creep ever-higher on the agenda for the United Nations, there's also a worldwide movement of using green roofs for hyper-local food production. In regions with suitable climates, hundreds of different vegetables, fruits, herbs and salad leaves can be grown on rooftops. Beehives and chicken coops are also becoming commonplace amongst the high-rises.

But what about solar power? With so many cities now divesting from fossil fuels, and the costs of solar panels dropping dramatically, photovoltaic (PV) systems have become the 'go to' option for generating distributed power in built-up areas. And, even with standard commercial panels, the energy gains are dramatic. The US National Renewable Energy Laboratory (NREL) have estimated that rooftop PV systems could generate almost 40% of electricity demands nationwide.

There's no doubt that in both cases, a network of 'productive rooftops' could benefit the local community by supplying a portion of a necessary resource – either food or electricity – while also reducing their environmental burden. But is one better than the other?

This was the question posed by researchers from MIT and the University of Lisbon in a recent paper in the journal Cities. Focusing on the rooftops of a mixed-use neighborhood in Lisbon, they carried out a Cost-Benefit Analysis for four scenarios. Starting with existing data on everything from installation costs and resources used, to carbon footprint and yield, they modelled the impact that each installation would have on the local community over a period of 50 years.

And by looking at it that way, they concluded that for Lisbon, the use of rooftops for food production could yield significantly higher local value than solar PV energy generation or standard green roofs. Of course, this is very site-specific - in another city, you might come to exactly the opposite conclusion, but that's kind of the point. There is no one-size-fits-all solution to make cities more sustainable, and anyone who tells you otherwise is massively over-simplifying a complex issue. Now, all I hope is that some of those decision makers start using it.

我们的城市从来没有像现在这样密集、高楼林立、繁忙,随之而来的是对土地不断的争夺。不管是城市居民、开发商、交通规划者还是农民,你都不得不加入对越来越少可用空间的角逐。预计到2050年全世界三分之二的人口将居住在城市,城市基础设施所受压力的增加似乎会让哪怕最深思熟虑的计划也跟不上步伐。但如果我们看看任何一个城市中心的鸟瞰图,我们就能很快发现大量未使用的空间——屋顶。
