问题 单项选择题

[背景材料]
某危险化学品储运公司拥有一个危险化学品库区,内设有三个危险化学品仓库,一个存有苯、甲苯、硫磺、黄磷这四种易燃物质,一个存有氧气,一个存有氮气、氩气等气体。库房总面积约550m2
该库区设有安全领导小组、义务消防队及专职安全机构等。公司职工共21人,其中技术管理人员3人、安全管理人员7人。库区内各种物质储存情况见下表:

品名 存量
3000kg
甲苯 3500kg
硫磺 2000kg
黄磷 2500kg
氧气 51瓶
氮气 50瓶
氩气 48瓶
根据以上场景,回答下列问题:

防止事故发生的安全技术措施中,在系统、设备、设施的一部分发生故障或破坏的情况下,在一定时间内也能保证安全的技术措施称为( )。

A.消除危险源

B.隔离

C.限制能量或危险物质

D.故障——安全设计

E.减少故障和失误

答案

参考答案:D

解析: 本题考核的是防止事故发生的安全技术措施。防止事故发生的安全技术措施是指为了防止事故发生,采取的约束、限制能量或危险物质,防止其意外释放的技术措施。常用的防止事故发生的安全技术措施有:
(1)消除危险源。消除系统中的危险源,可以从根本上防止事故的发生。但是,按照现代安全工程的观点,彻底消除所有危险源是不可能的。
(2)限制能量或危险物质。限制能量或危险物质可以防止事故的发生,如减少能量或危险物质的量,防止能量蓄积,安全地释放能量等。
(3)隔离。隔离是一种常用的控制能量或危险物质的安全技术措施。采取隔离技术,既可以防止事故的发生,也可以防止事故的扩大,减少事故的损失。
(4)故障——安全设计。在系统、设备、设施的一部分发生故障或破坏的情况下,在一定时间内也能保证安全的技术措施称为故障——安全设计。通过设计,使得系统、设备、设施发生故障或事故时处于低能状态,防止能量的意外释放。
(5)减少故障和失误。通过增加安全系数、增加可靠性或设置安全监控系统等来减轻物的不安全状态,减少物的故障或事故的发生。

Beijing opera or Peking opera (Pinyin: Jīngjù) is a form of Chinese opera which arose in the late 18th century and became fully developed and recognized by the mid-19th century.The form was extremely popular in the Qing Dynasty court and has come to be regarded as one of the cultural treasures of China.Major performance troupes (剧团,戏班子) are based in Beijing and Tianjin in the north,and Shanghai in the south.The art form is also enjoyed in Taiwan,and has spread to other countries such as the United States and Japan.

Beijing opera features four main types of performers.Performing troupes often have several of each variety,as well as numerous secondary and tertiary performers.With their elaborate (认真的,精心的) and colorful costumes,performers are the only focal points on Beijing opera's characteristically small stage.They make use of the skills of speech,song,dance,and combat in movements that are symbolic and suggestive,rather than realistic.Above all else,the skill of performers is evaluated according to the beauty of their movements.Performers also hold a variety of stylistic conventions that help audiences navigate the plot of the production.The layers of meaning within each movement must be expressed in time with music.The music of Beijing opera can be divided into the Xipi and Erhuang styles.Melodies include arias (唱腔),fixed-tune melodies,and percussion patterns.The repertoire of Beijing opera includes over 1,400 works,which are based on Chinese history,folklore,and,increasingly,contemporary life.

In recent years,Beijing opera has attempted numerous reforms in response to sagging audience numbers.These reforms,which include improving performance quality,adapting new performance elements,and performing new and original plays,have met with mixed success.Some Western works have been adopted as new plays,but a lack of funding and an adverse political climate have left Beijing opera's fate uncertain as the form enters the 21st century.
