【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(nèi)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(hù)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(jù)日常生活中,我們要學(xué)習(xí)一些在火災(zāi)、地震、水災(zāi)中逃生的科學(xué)知識,在一些突發(fā)事件中,要充分利用科學(xué)知識,進(jìn)行逃生,進(jìn)行分析解答。
地震是一種突發(fā)性自然災(zāi)害,目前尚難以準(zhǔn)確預(yù)報。一旦發(fā)生地震,人們應(yīng)保持冷靜并迅速采取措施進(jìn)行自我保護(hù),“小震不用跑,大震跑不了,驚慌出意外,就地躲避好!比绻卣疬未開始,但已聽見地聲或看見地光,應(yīng)立即關(guān)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(yīng)盡快尋找空間狹小或有管道通過的地方如衛(wèi)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(yīng)注意保護(hù)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(guān)死,出逃時應(yīng)打開出入口,確保人員迅速撤離。正在行駛的車輛應(yīng)立即停車。在山谷等特殊地段,應(yīng)警惕山崩、滑坡等發(fā)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(qū)。地震發(fā)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(shè)法找到食物和水,千萬不要大喊大叫,避免體力消耗過多。當(dāng)聽到外面有人時,再設(shè)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(jī)收聽廣播,以獲取準(zhǔn)確信息;結(jié)合題意。故選A。
