All chemical burns — this includes burns due to acids and bases — should be treated by a doctor. Although injuries due to chemicals are called burns and are classified in the same way (first to sixth degree), these burns are not as easy to treat as normal burns that have been cause by fire and heat. Unlike burns caused by fire, with chemical burns the cause of the injury often remains on and in the body, and treatment must include removal of the chemical. With chemical burns, the full extent of the damage may also not always be obvious. In addition, depending on what chemical substance caused the burn, a home remedy might just end up worsening your condition. It is therefore best not to try to treat chemical burns yourself.
Some first aid measures however are always necessary. The first thing you should do is to take off any clothes or jewellery that the chemical has spilled onto. Next, wash the chemicals off your skin. This should be done for at least 15 minutes, with the tap as far open as possible. Note however, that certain chemicals such as lime and hydrochloric acid will react with water and cause further injury. If these are the chemicals in question or if you don't know what has burnt you, simply wipe or brush off the chemical. Finally, get to a doctor as soon as you can. One of the most important things to remember in all of this is to make sure you do not get the chemical into your eyes.
