If you use fire carefully, fire can help you a lot. But if you don't, you will be dangerous.
People know the danger of fire. It's good for us to know how to protect us from fire.
First, get a smoke alarm in the house. It can make a loud sound. The sound tells everyone to leave the house immediately（立刻） in case of emergency（紧急情况）.
Next, have an escaping（逃生）plan. Make sure we all know where is the safety exit（出口） of your house. In case of fire emergency, everyone should follow the right way to escape.
Then, it is necessary for every family to buy a fire extinguisher（灭火器）. And also make sure that every family member know how to use it.
