How dangerous it would be if there was a fire! Winter is the time for us to learn a lot more about fire, especially what to do if we are caught in a fire.

1. Shout out If you smell smoke or see fire, shout out “Fire!” Shout as loudly as you can, because people may be asleep.

2. Call 119 Never try to put out the fire yourself, even if it is a very small one! Get help from your parents or call 119.

3. Keep down close to the floor If there is a lot of smoke in your room, keep down close to the floor.

4. Test the door Test the door before you open it. If the door is cool, open it carefully. If the door is hot, do not open it! Try to find a different way out.

5. Get out If you can, get out of your home as soon as possible.

6. Don’t use the lift Never use the lift during the fire. It may also go wrong.

7. Don’t go back Never go back into a burning building!
