Fires that happen in the home are a very serious problem today. In
America, there are over 100,000 home fires every year and many
start in the kitchen. There are a lot of things you can do to protect
your house from fire. First of all, you need to follow a few safety
rules. You should never leave the kitchen while you are cooking.
It’s also a bad idea to wear loose clothes when you cook. Always
keep the cooking area clean and don’t let children come very close
to the cooker. It is also important to know what to do if a fire
starts. If a pan catches fire, don’t throw water on it! Put a blanket
over it and turn off the heat. If the fire doesn’t go out, call the fire
brigade. If a fire starts inside the oven, keep the door shut and turn
it off. If you burn yourself, run cold water over the burn. Finally,
install a smoke alarm and learn how to use it. Also, know the
number of your fire brigade by heart. It’s better to be safe than
sorry.
1) In America, there are more than 100,000 home fires a year.
2) Call the fire brigade if a fire doesn’t go out right away.
3) Children should stay close to the cooker.
4) A lot of home fires start in kitchens.
5) You should keep your cooking area clean.
6) If a fire starts, pour water on it to put it out.
7) You should have a smoke alarm and know how to use it.
8) You shouldn’t wear loose clothes when cooking.
9) There’s not much we can do to stop fires.
10) You should always leave the kitchen while cooking.
