C

Could the solution to world future energy needs lie in the ocean? It’s possible.

We are not talking about oil, but another potential untapped energy resource called “methane hydrates”.

Methane hydrates are hard, ice-like white solids that form naturally in deposits (沉积物) on ocean floors. They arecomposed of water and highly concentrated methane produced by the microorganisms living in the deposits.

The remarkable thing is that you can hold a flame to a piece of methane hydrate and it will catch on fire. It’s been called “burning ice.”

Methane hydrates are spread around the world. These deposits may in the future become a very important fuel resource. One researcher calculated that a small area off the Southeastern coast of America may contain methane hydrates equal to 30 times the annual U.S. consumption of natural gas.

Right now there are very significant technical and financial challenges facing us before we could exploit this as a resource. Scientists around the world are studying these challenges. One big issue is how to get these methane hydrates off the ocean floor, causing undersea landslides and tidal waves.

Another issue is how to handle the matter after it is brought up. It’s also unclear whether it would make more sense to “mine” solid hydrates or tap the gases found with them. And many deposits may occur in low concentrations with no commercial potential.

Japan, which has no oil supplies of its own, has thrown itself into burning ice research because it has deposits off its shores which could make Japan less dependent on foreign suppliers of oil.

The U.S. Department of Energy and Congress are also supporting research. However, the US administration’s energy policy is focused on traditional fossil (化石) fuels. And at least for now, developing burning ice into a fuel source isn’t high on the energy industry’s list. But if natural gas continues to rise in price, exploiting burning ice might become economically practical.

问答题

总部位于A省的某集团公司在B省有甲、乙、丙三家属企业。为加强和规范应急管理工作,该集团公司委托某咨询公司编制应急救援预案。咨询公司同感哦调查、分析集团公司及下属企业的安全生产风险,完成了应急救援元起草工作,提交到集团公司会议上进行评审。评审时,集团公司领导的意见是:

(1)集团公司和甲、乙、丙三家企业的应急救援预案在应急组织指挥结构上应保持一致;

(2)集团公司有自己的职工医院和消防队,应急救援时伤员救治要依靠职工医院,抢险力量队伍要依靠集团公司消防队;

(3)周边居民安全疏散,应由集团公司通知地方政府有关部寻由地方政府组织实施;

(4)应急救援预案中因部分内容涉及集团公司商业秘密一应急救援预案不对企业全体员工和外界公开,只传达到各企业中层以上干部;

(5)应急救援预案要报A省安全生产监督管理部门备案。近期,该集团公司完成了一套应急救援预案的演练计划。

该计划设计的演练内容为:

(1)打开液氨储罐阀门,将液氨排到储罐的围堰内;

(2)参演人员在规定的时间内关闭阀门,将围堰内的液氨进行安全处置;

(3)救出模拟中毒人员。   

2008年3月6日,集团公司在甲企业进行了应急救援实战演练,演练地点设在甲企业的液氨储罐区。为保障参演人员、控制人员和观摩人员的安全,集团公司事先调来乙企业全部空气呼吸器、防毒菌具、。防爆型无线对讲机和监测仪器,同时调来集团公司消防队所有的水罐车、泡沫车和职工医院的救护车辆。

演练从10点钟开始,按照事先制订的演练计划进行:   

10点20分氨气扩散到厂区外,由于演练前未组织周边群众撤离,扩散的氨气导致两名群众中毒:

10点30分,抢救完中毒群众后,演练继续按计划进行。   

根据以上场景,回答下列问题:

结合本案,简述事故应急救援的基本任务。
