3. We should put damp cloths on the second degree burns.
4. We shouldn’t break the blisters, or they will make the wound infected.WRRR5. Sometimes, we can put oil or ointments on burns to stop the infection.
6. We should make sure the bandage won’t stick to the skin when it is used.
7. If burns are on the face, we should make the victim sit up.
8. Cold water can be used in three types of burns.WWRREx 3 Answer the questionsWhy 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 prevents or
reduces swelling（肿）. Because in a 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 layers of the skin have
been burnt showing the tissue underneath.1. Sam knocked over a kettle full of boiling water onto his legs. His legs became red, swollen and covered with blisters.
