People know the dangers of fires. It's good for a family to learn how to prepare for a fire. Here are some suggestions:
. Smoke from a fire causes the alarm (报警) to go off. The alarm makes a loud sound. The sound tells everyone to leave the house at once.
. They should know all the ways out of the house. If there is a fire, everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily (容易地).
Buy fire extinguishers (灭火器) in the house. Everyone in the family should know how to use them.
. They do fire practice because they teach children about fire safety. Everyone in the family should know the following fire rules:
. The fire can grow more quickly if you open the door. Stay close to the floor! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises (上升).
. First, stop! Don't run! The fire burns faster because of more air. Drop! Fall to the floor. Then roll (滚动)! Turning over and over will make the fire go out. Put a blanket (毯子) around you to keep air away from the fire that may still be on you.
A clever family is ready all the time. If there is a fire, don't forget to call 119 for help.
