Safety Profile
Dangerous fire hazard by spontaneous chemical reaction. It is a very powerful oxidzer. Fires of this material should be handled like sodurn peroxide fires. Moderate explosion hazard by spontaneous chemical reaction. Explodes on contact with water, forming H2O2 and KOH. Violent reactions with air, Sb, As, O2 , K. Vigorous reaction on contact with reducing materials. On contact with acid or acid fumes, it can emit toxic fumes. Incompatible with carbon, diselenium dichloride, ethanol, hydrocarbons, metals. When heated to decomposition it emits toxic fumes of K2O . See also PEROXIDES, E INORGANIC.
