POTASSIUM BINOXALATE 323

Not to be Used: Water, foam, carbon dioxide, or halogenated hydrocarbons; Special Hazards of
Combustion Products: No data; Behavior in Fire: Reacts violently with water, forming flammable and
explosive hydrogen gas. This product may spontaneously ignite in air; Ignition Tempemture : No data;
Electrical Hazad Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: Reacts violently forming flammable hydrogen gas and
a strong caustic solution; Reactivity with Common Materid: May ignite combustible materials if they
are damp or moist; Stability During Transport: Stable if protected from air and moisture; Neutralizing
Agents for Acids and Caustics: Caustic that is formed by the reaction with water should be flushed with
water and then can be rinsed with dilute acetic acid solution; Polymerization: Not pertinent; Inhibitor
of Polymerization: Not pertinent.
