美国的学校的每层楼，宿舍区的每一个房间，都会装有火灾警报器，每一个学期开始不久，就会有专门的人员来检查这些警报器是否能够正常工作。这些警报器很敏感，有时候中国学生在厨房烧菜，油烟大一点，就会引发厨房警铃大作。

今天突然间，火警大作。我们还在疑惑是不是谁的手机铃声，就有工作人员推开教室门，通知疏散。紧接着，我们就被指引从逃生楼梯，以最快的速度到达底楼。

我不得不钦佩美国人对人生安全的重视。其实这样的警报，有可能是谁在走廊抽了一支烟，也有可能是谁的恶作剧或出于无心，按响了警铃。但是只要有了不安全因素，就一定要等到排查后才能重新开课。这幢楼，共八层，最后一个学生到达底楼空地的时间距离警铃作响不超过15分钟。这样的效率和谨慎，让每一个在美国教室里学习的学生都充满安全感。

国内学校对学生安全的关注程度没有足够的高，甚至很多学校从未开设过紧急逃生课，从未普及安全防范知识。我们一起来看看美国对火灾的预防和逃生措施吧。

1.Plan a fire escape route and practice it once a year, change smoke alarm batteries twice a year, and test your smoke alarm once a month. The meeting place should be in the front yard. Don't do it in the back because you'll lose sight of your family. Plus, it's hard to get in the front without going inside the house.

2.Listen for the smoke alarm. After it rings, don't stay in your room. You must get out immediately.

3.Go close to your door. With the back of your hand, not your palm, feel the door. If it's cool to the touch, open it slowly with your back facing the door but also looking where you're going. If it's hot dial 911. If there is not a phone in the room, get a flashlight or something light colored and wave it at the window signaling for help. If it's not cool and not hot, just medium, open it slowly as shown when it's cool.

4.Crawl down on the floor after opening it. The cleanest air is found at the bottom. Get out of where the fire is, and leave the house.

5.Go to a neighbor's house and call 911.

6.Wait until the fire department comes.
