关于安全知识的小常识,我给大家介绍以下几种灭火器:
泡沫灭火器。使用时将灭火器颠倒,左右摆动,使药剂混合,产生二氧化碳气体的泡沫受压喷出。适用于扑救木材、棉、麻、纸张等火灾。
二氧化碳灭火器。使用时拔出灭火栓,一只手握住灭火器,另一只手握住灭火柄,然后压下握把开关,将内部的气体喷出。
干粉灭火器。这是一种最常见的灭火器,使用时拆掉封条,拿起喷管朝着有火的地方喷去。这种灭火器可以扑灭可燃气体、液体。
现在我来介绍安全小知识:
当我们碰到火灾有浓烟的时候,要用毛巾、口罩之类的东西折叠八层后捂着鼻子,然后贴近地面爬,如果发现门已经发烫了就千万不要开门,要用湿毛巾、湿地毯什么的塞住门缝,然后用水不停地淋房门,要在背火的窗口呼救,如果大家都知道消防知识就会减少人员的伤亡。一旦受到火灾威胁,千万不要惊慌失措,要冷静地确定自己所处的位置,根据周围的烟、火光、温度判断火势,不要盲目采取行动。火灾时不能使用电梯逃生。因为失火后电梯竖井往往成为烟火的通道,电梯随时可能发生故障。正确的方法是通过防火通道走安全通道的楼梯脱险。

今天下午,我们班一起开班会,班会的主题是防火小知识。
里面的内容是,首先,老师给我们讲了怎样防火,怎样不引起火灾,老师还讲了如果发生了火灾,该怎么办,怎样使用灭火器,那种能引起火灾……,这时候,有一位同学大喊,着火了!然后我们赶紧站起来,把红领巾捂住嘴巴和鼻子,然后蹲下来,跑到足球场,然后集合,最后王校长和白主任……在说关于火灾的话题,最后我们就回班了。
这次的防火灾演习让我知道了一些关于怎样防火的小知识。
When I was a freshman in college I watched the film Gua Sha Treatment for the first time, now I am a junior student and I come back to review the movie from a multicultural aspect, I have many different feelings after watching the film again.
At the beginning of the film, XuDatong is given an award and later he delivers a speech. What makes me impressed most is in his speech he says “one day I will become one of you, a truly successful American, today this award proved that America is a true land of opportunity and I am the living proof of that.” At that moment Xu thinks he has realized his American Dream totally with his lovingly wife and adorable son. However, I think it is ironical that to make a speech like that and I assume it is made on purpose to hind a clue for the story\'s development. How many non—American people have such a beautiful American dream? One of my classmate studies in American now and before he went aboard he told me his American dream is he can stand at the top of the New York. To be honest, I also dream that one day I can get the Green Card living there happily and successfully maybe working at the Wall Street. When Xu gets the award he thinks he entirely melted in the melting pot neglecting the multicultural obstruct, later the plot goes against the way he thinks. And later Quinlan asked Xu\'why you be the scapegoat of your father?\' Xu answers \'because he is Chinese.\' Then maybe Xu knows that there is always a wide gap between Chinese and American cultures.
The second scene is Xu hit his son Denis because Denis hit the son of xu\'s boss, at the middle of the film xu tells his boss that he hit his own son is only to show his respect to his boss John Quinlan, that time Quinlan feels puzzled “what a Chinese logic”,yes, American can never understand such a logic full of Chinese characteristic, because they respect everyone including the children, they won\'t beat a child to please the boss, and there is no such a conception of degree between employee and employer, they feel everyone is equal, which is quite different from china.
Connected to the second scene, the third difference I want to analyze is the care for the children. In America, people pay more attention to the right of children which can be seen from the law—leaving children alone at home is illegal, while in China it is so common that almost everyone may experience such loneliness. And Children Welfare Agency does work in America which shows the importance Americans attach to children\'s right. What\'s more, I remember a line \'No one won the case, especially the child.\' In my opinion, it also manifests the universal concern from the American public to the children.
The fourth aspect is following the procedure, in the film, more than there times, the people focus on the rule, the law, the procedure. At the Christmas Eve Xu wants to return back to his home pretending as a Santa Claus, what a pity, the security recognizes him and persuades \'you are always a good tenement, never causes troubles for me.\' And another scene is at the end of the film , the judge says \'I have to follow the procedure.\' However, in China people always have to ask for a favor to do something, and later you have to pay back the favor,for myself, I prefer the American style, strict to the procedure.
The fifth and the last point is the humors, Quinlan says \'you can\'t fall, your health security is the company paid.\' \'Datong, welcome home, maybe next time, you can come from the front door.\' \'dady, why you come from the window\' \' because we don\'t have a chimney.\' I really adore this distinguished American humor, especially in dangerous situations, which is quite rare in China.
That\'s my whole reaction to Gua Sha Treatment.
