Make escape (逃脱) plans. They should know all the ways of getting 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.

Buy fire extinguishers (灭火器) in the house. Everyone in the family should know how to use them.

Practice for a fire. They do fire practice because they 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.
