【題目】地震時,正確的逃生和自救措施非常重要。以下措施錯誤的是( )
A.在室外跑到堅固的樓內躲避
B.地震時切忌急著沖出門,請勿使用電梯
C.在室外,避開高大建筑物雙手護頭蹲下
D.被壓廢墟下不要急躁,想辦法維持生命尋求救援
【答案】A
【解析】
根據日常生活中,我們要學習一些在火災、地震、水災中逃生的科學知識,在一些突發事件中,要充分利用科學知識,進行逃生,進行分析解答。
地震是一種突發性自然災害,目前尚難以準確預報。一旦發生地震,人們應保持冷靜并迅速采取措施進行自我保護,“小震不用跑,大震跑不了,驚慌出意外,就地躲避好。”如果地震還未開始,但已聽見地聲或看見地光,應立即關閉煤氣,澆滅火爐,切斷電源,用最快的速度離開房屋,到戶外空曠處躲避。地震時來不及撤離者,應盡快尋找空間狹小或有管道通過的地方如衛生間或墻角等躲藏,或躲在桌子等堅固家具下,在地震過后迅速撤出時應注意保護頭部,避開玻璃門窗、圍墻、電線桿、大型廣告牌等。在教室或人群集中的公共場所,要冷靜行動,聽從指揮,震動會使門窗變形而自動關死,出逃時應打開出入口,確保人員迅速撤離。正在行駛的車輛應立即停車。在山谷等特殊地段,應警惕山崩、滑坡等發生,遇到山崩、滑坡,要向與山崩、滑坡的垂直方向跑,盡快撤至安全地區。地震發生后如果被壓在塌房里,首先盡量除去壓在身上的重物,并設法找到食物和水,千萬不要大喊大叫,避免體力消耗過多。當聽到外面有人時,再設法讓別人知道你的位置,及時獲救。不要聽信謠言,可用收音機收聽廣播,以獲取準確信息;結合題意。故選A。
