     People know the dangers of fires. It's good for a family to learn how to prepare for a fire. Here are

some suggestions:

    ● put a smoke alarm in the house. Smoke from a fire causes the alarm to go off. The alarm makes

         a loud sound. The sound tells everyone to leave the house at once.

    ● Make escape plans. They should know all the ways out of the house. If there is a fire, everyone

         follows the plan to go out. Part of the plan is to check all the windows to make sure they can be

         opened easily.

    ● Put the extingushers (灭火器) in the house. Practise for a fire. They do fire pratice because they

         teach childen about fire safety. Every-one in the family should know the following fire rules.

    ● Don't open a hot door! The fire can grow more quickly if you open the door.

    ● Stay close to the door! Smoke can be more dangerous than fire. The best air is near the floor because

         smoke rises.

    ● What will you do if your hair or clothes start to burn? First, stop! Don't run! The fire burns faster

         because of more air. Drop! Fall to the floor! Rolling over and over will make the fire go out. Put a

         wet blanket (毯子) around you to keep air away from the fire that may still be on you.

    ● There are many possible causes for fires. A wise family is ready all the time.If there is a fire, don't

         forget to call 119 for help.
