November 9 is a time for us to learn a lot more about fire(火). This is what to do in a fire:

1.Shout out. Shout as loudly as you can, because people may be asleep.

2.Call 119. Never try to put out a fire yourself. Tell 119 where you are and what is on fire.

3.Keep down close to the floor. There is less smoke down there, so it’s easier to breathe and see where you are going.

4.Test the door. If the door is cool, open it carefully. If the door is hot, do not open it! Try to find a different way out.

5.Get out. Do not stop to pick up anything. A fire can become very big in a few seconds!

6.Don’t use the lift. Always use the stairs. The lift may go wrong and keep you inside.

7.Don’t go back .Even if you have left your pet or favorite toy inside, do not go back for it. Animals have a very good sense of smell. They often get out of buildings before people.
