Safety

Dangerous fire hazard by chemical reaction. Ignites spontaneously in air. Moderate explosion hazard when exposed to heat or by chemical reaction. Will react with water, steam, or acids to produce H₂ which then ignites. Can react vigorously with oxidizing materials. To fight fire, use CO₂, dry chemical. Potentially explosive reactions with o-2,4-dinitrophenylhydroxylamine, fluoroalkenes. Ignites on contact with air, oxygen + moisture, fluorine. Incompatible with Cl₂, acetic acid, acrolein, acrylonitrile, (CaC + Cl₂), ClO₂, (H₂O₂ + Cl₂), (CHFl₃ + CH₃OH), 1,2-dichloroethylene, maleic anhydride, (n-methyl-n-nitrosourea + CH₂Cl₂), nitroethane, NCl₃, nitromethane, nitroparaffins, o-nitrophenol, nitropropane, n-nitrosomethylurea, (nitrosomethylurea + CH₂Cl₂), H₂O, trichloroethylene, tetrahydrofuran, tetrachlorethane. When heated to decomposition it emits highly toxic fumes of K₂O. See also POTASSIUM and HYDRIDES.
