For second‑degree burns, the skin becomes swollen with blisters. Cool water is helpful, which can stop burning process and reduce swelling. Remember never put butter or oil on wounds, because it may cause infection. If it is a third‑degree burn, the nerves may be damaged. We should not pull off the stuck clothing and should call for professional medical help quickly. 提升层参考范文 Our skin acts as an important barrier protecting our body. Once people get burnt, we need to tell different types of burns apart. First‑degree burns affect only the top layer while third‑degree burns may damage nerves and tissue underneath. When dealing with burns, use cool running water to stop heat and ease pain. Never apply butter or oil, for they will keep heat inside and bring infection. If it is a serious third‑degree burn, do not remove clothes sticking to wounds and we must send the patient to hospital as soon as possible. 06.

I stayed calm and helped her sit down first. I cleaned the wound and put a bandage on it to prevent it from getting worse. Finally, our teacher called the school doctor. From this experience, I learned that a knowledge of first aid can help us deal with small accidents. If we can react quickly, we may make a big difference in an emergency. 提升层写作参考范文 First Aid in Daily Life In daily life, we may suddenly be faced with small accidents, such as falls, burns or fainting. If someone gets injured, it is important to stay calm first. We can give first aid by cleaning wounds, pressing the bleeding area or moving the person to a safe place. If the situation is serious, we should call an ambulance immediately. A knowledge of first aid can prevent an accident from becoming worse. It can really make a difference when every second counts. Therefore, we should learn basic first aid skills and be prepared for emergencies. Thanks for listening! $
