Why should you put cold water on a burn? 2. Why doesn’t a third degree burn hurt? Because the cold water stops the burning process, stops the pain and reduces the swelling. Because in the third degree burn the nerves have been damaged. If there are no nerves, there is no pain. 3. Why do you think clothes and jewellery near burns should be removed? 4. If someone has a third degree burn, why might you see tissue? Because bacteria from the clothes and jewellery could infect the burns. Because all the layers of the skin have been burnt showing the tissue underneath. 4 Read the first aid treatments for these burns. If the treatment is right, write R in the brackets. If it is wrong, write W in the brackets and explain why. Then give the correct treatment. 1 Wrong: Sam should not have broken the blisters because the burns could bee infected. He should have poured cool water, not icy water on the burn. 2 Right. 3 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 Right. 1.
