Alkaline chemical burns. Basically, the degree of this kind of burn is directly proportional to the concentration of lye and temperature, which will make the contact skin fester. If there is no obvious discomfort at that time, it should be a slight burn. There will be no major problem after washing with a large amount of warm water. Koh is easily soluble in water, and it will not penetrate into the skin and cause any internal damage. You may find that your burned area is molting in a few days. It will be all right when you molt it clean and grow a new skin. But next time we must pay attention to safety. If you encounter it unfortunately again, immediately wash it with a large amount of cold water. If there is obvious pain, you can appropriately coat the affected area with boric acid / acetic acid solution. In case of skin ulceration, remember to go to the infirmary to clean it up, and do a good job in the antibacterial treatment of the exposed parts of the skin and meat to avoid bacterial infection.

氫氧化鉀溶液接觸皮膚的主要危害是腐蝕皮膚。按照你的描述，氫氧化鉀溶液應該只有少量濺到皮膚，這種情況需要及時沖洗，如果皮膚有明顯紅腫或疼痛則需要就醫(yī)。如果皮膚沒有明顯變化也沒有疼痛的話一般就沒什么大問題。氫氧化鉀溶液有腐蝕性但無毒，高濃度的氫氧根導致腐蝕性。鉀離子接觸皮膚不會造成損傷，畢竟細胞內也含有大量鉀離子

The main harm of potassium hydroxide solution in contact with skin is to corrode the skin. According to your description, only a small amount of potassium hydroxide solution should be splashed on the skin, which needs to be washed in time. If the skin has obvious redness or pain, you need to see a doctor. If there is no obvious change in the skin and no pain, there is generally no big problem. Potassium hydroxide solution is corrosive but non-toxic, and high concentration of hydroxyl causes corrosion. Potassium ions will not cause damage when contacting the skin. After all, cells also contain a large amount of potassium ions
