Hazardous Substances Data：

7440-09-7(Hazardous Substances Data)

Toxicity：

Ignites in air and reacts explosively with water; highly corrosive to the skin and eyes. Potassium reacts with the moisture on skin and other tissues to form highly corrosive potassium hydroxide. Contact of metallic potassium with the skin, eyes, or mucous membranes causes severe burns; thermal burns may also occur due to ignition of the metal and liberated hydrogen.
