If someone has stopped breathing, you must try to start his/her breathing at once.

If the person is bleeding badly, you must try to stop the bleeding.

If you are bitten by an animal like a fierce dog, you must do something at once. The cold running water is the best and doctors are needed.

If you are burnt (hurt by fire or something very hot), deal with the burnt part at once. The cool water is better.

If there is a fire in a building, stairs are safe and lift is dangerous.

A. Don't use lift. The lift may get trapped( 被困) between floors. Use the stairs and leave the building at once.

B. Clean the wound. Use cold running water to clean the wound. Then stay at home to have a rest at once.

C. Wash the wound. Wash the wound under running water. Cover the broken part, if there is any, with a piece of clean cloth. Then see a doctor as soon as possible.

D. Press hard. You should press on the bleeding point with a piece of clean cloth and hold up the part to the body which is bleeding.

E. Perform CPR. Blow into the person's mouth then press on his/her chest and then repeat the process.

F. Use the lift. Lift is convenient. Take the lift to the first floor and you can go to see the doctor quickly.

G. Cool the burnt. Run cool (not cold) water over the burnt part until it is less painful. Put a piece of dry clean cloth over the burnt part.
