Comments
Toxic by ingestion--causes gastrointestinal burns; Other adverse effects are methemoglobinemia, and injury to liver and kidneys; For a child, a lethal dose of 1 teaspoonful of potassium permanganate crystals was reported; Lethal dose is about 10 grams for an adult; [HSDB] A strong oxidizing agent; May spontaneously ignite combustible liquids; [CAMEO] Potassium permanganate crystals and concentrated solutions (greater than1:5000 strength) are corrosive (release potassium hydroxide when contact water); Permanganates can induce methemoglobinemia after ingestion; [Olson, p. 133] See "Zinc." See "Manganese" and linked occupational diseases.
