Discussion
Sam knocked over a kettle full of boiling water onto his legs. His legs became red, swollen and covered with blisters. Sam broke the blisters and poured icy water from the fridge onto the skin.
w
( group work )
Wrong: Sam should not have broken the blisters because the burns could become infected. He should have poured cool water, not icy water on the burn.
2. While ironing clothes, Miss Good accidentally touched the iron. Her wrist blistered and became watery. It hurt a lot. She put her wrist under the cold water tap and then kept placing cool, clean, damp cloths on it until it was less painful. Then she went to see the doctor.

3. Mrs Casey’s sleeve caught fire while she was cooking. Her arm looked terrible but it didn’t hurt. The skin was charred. Her husband took off her blouse and picked off bits of the blouse stuck to the burn. He then placed butter on the burn and covered it with a wet bandage.
w
Wrong: Mr Casey was right to take his wife’s blouse off but he should not have picked bits of blouse off the burn. The correct first aid treatment for a third degree burn is to remove clothing and jewellery near the burn but not if the clothing is stuck to the burn. He should not have put butter on the burn because it would have stopped the heat from escaping.
4. After an hour in the sun, Lily noticed her arms were red and hurt a bit. She went home and put them under running water.

Accidents can happen to anyone at any time.
But you can be the difference between life and death. So try to learn more about first aid in daily life.
