问题 单项选择题

某承建单位根据《电子信息系统机房设计规范》中电子信息系统机房C级标准的要求,承担了某学校机房的施工任务。在施工中,______行为是不正确的。

A.在机房防火方面遵守了二级耐火等级
B.在机房内设置了洁净气体灭火系统,配置了专用空气呼吸器
C.将所有设备的金属外壳、各类金属管道、金属线槽、建筑物金属结构等进行等电位连结并接地
D.将安全出口的门设为向机房内部开启

答案

参考答案:D

解析: 《电子信息系统机房设计规范》指出:
电子信息系统机房应根据使用性质、管理要求及由于场地设备故障导致网络运行中断在经济和社会上造成的损失或影响程度,将电子信息系统机房划分为A、B、C三级。
A级为容错型,在系统需要运行期间,其场地设备不应因操作失误、设备故障、维护和检修而导致电子信息系统运行中断。
B级为冗余型,在系统需要运行期间,其场地设备在冗余能力范围内,不应因设备故障而导致网络系统运行中断。
C级为基本型,在场地设备正常运行情况下,应保证网络系统运行不中断。
在异地建立的备份机房,设计时应与原有机房等级相同。同一个机房内的不同部分可以根据实际需求,按照不同的等级进行设计。
《电子信息系统机房设计规范》从机房位置及设备布置、环境要求、建筑与结构、空气调节、电气技术、电磁屏蔽、网络布线、机房监控与安全防范、给水排水、消防等多个方面对设计规范进行说明。
建筑与结构部分“防火和疏散”中指出:电子信息系统机房的耐火等级不应低于二级;面积大于60m2的主机房,安全出口应不少于两个,且应分散布置,宜设于机房的两端。门应向疏散方向开启,且能自动关闭,并应保证在任何情况下都能从机房内开启。走廊、楼梯间应畅通,并应有明显的疏散指示标志。
电气技术部分“静电防护”中指出:电子信息系统机房内所有设备可导电金属外壳、各类金属管道、建筑物金属结构等均应作等电位连接,不应有对地绝缘的孤立导体。
消防部分“安全措施”中指出:凡设置洁净气体灭火的主机房,应配置专用空气呼吸器或氧气呼吸器。
可见选项D是不正确的。

Here is a true story about a famous man who worked in the White House and a criminal. They once faced the same thing: their mother gave them apples when they were young.

The criminal said: one day, my mother brought some apples and asked my brother and me: “Which do you want?” “The reddest and biggest one,” my little brother said. My mother stared at him and said to him angrily: “You should learn to give the good things to others; you shouldn’t always think of yourself.” Seeing this, I suddenly changed my idea and then said to my mother: “Mum, please give me the smaller one and give the bigger one to my little brother.” Hearing my words, my mother was very happy. She kissed me on my face and gave the reddest and biggest apple to me as a prize. From then on, I learned to tell lies, fight, steal and rob. In order to get what I wanted, I played hard. As a result, I was sent into prison.

And I will give the reddest and biggest apple to him who does it the most quickly and best.”
