The skin is an essential part of your body and is its largest organ. Your skin acts as a barrier against disease, toxins, and the sun’s rays. It also helps control your body temperature, prevents your body from losing too much water, warns you when things are too hot or cold, and gives you your sense of touch. As you can imagine, getting burnt can lead to very serious injuries. The first and most important step in the treatment of burns is giving first aid.

Types of burns
Burns are divided into three types, depending on the depth of skin damage.
◎ First-degree burns These affect only the top few millimetres of the skin. These burns are not serious. Examples include mild sunburn and burns caused by other minor household incidents.
◎ Second-degree burns These go below the top layer of the skin. They are serious and take a few weeks to get better. Examples include burns caused by hot liquids.
◎ Third-degree burns These affect every layer of the skin, and sometimes the tissue under it. Examples include burns caused by electric shocks, burning clothes, or petrol fires. These burns cause very severe internal injuries and the victim must go to hospital at once.

2. What steps can be taken to help prevent these burns
Being aware of the danger is a good first step. For example, you should check to see if the burner is on before touching a pan on the stove. You should also use oven mitts (微波炉手套) when touching a hot pan. If you are using cooking oil, you should make sure that the pot is set firmly on the stove so that it cannot spill, and that it is not too full of oil.
