Vigorous polymerization is potentially hazardous because the reaction may get out of control. Once started, the reaction is accelerated by the heat that it produces. The uncontrolled buildup of heat and pressure can cause a fire or an explosion, or can rupture closed containers.
Potassium permanganate - Wikipedia
Potassium permanganate is an inorganic compound with the chemical formula KMnO4 and composed of K+ and MnO− 4. It is a purplish-black crystalline solid, that dissolves in water to give intensely pink or purple solutions.[citation needed] Potassium permanganate is widely used in chemical industry and laboratories as a strong oxidizing agent
