We all know the dangers of fires. It’s good and necessary 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（逃生）plans. We 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.
Put fire extinguishers（灭火器）in the house. Everyone in the family should know how to use them.
Practice for a fire. We do fire practice because we teach children about fire safety. Everyone 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 floor to keep away from the smoke! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises.
●What will you do if your clothes start to burn? First, stop! Don’t run! The fire burns faster because of more air. Fall to the floor. Then roll（打滚）!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 wise family is ready all the time. If there is a fire, don’t forget to call 119 for help.
