Hazard Information

Chemical Properties
White to pale yellow powder
General Description
A white powder or sandy yellow granular solid. Irritates skin, eyes and mucous membranes. Used to produce a supply of high-purity oxygen.
Reactivity Profile
LITHIUM PEROXIDE(12031-80-0) is strongly basic and an extremely powerful oxidizing agent. Accelerates the combustion of other materials, especially organic materials, involved in a fire. Can ignite wood, paper, oil, clothing, etc. on contact. May react explosively with hydrocarbons (fuels). Exposure to heat in a closed container may result in a vigorous reaction that violently ruptures the container.
Air & Water Reactions
Contact with water or moist air generates a large amount of heat and corrosive, alkaline lithium hydroxide [AAR 1991].
Health Hazard
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire may produce irritating and/or toxic gases. Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Runoff from fire control or dilution water may cause pollution.
Fire Hazard
May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard.

Safety Profile
A powerful oxidizer and irritant to skin, eyes, and mucous membranes. A very dangerous fire hazard because it is an extremely powerful oxidizing agent. Will react with water or steam to produce heat; on contact with reducing materials, can react vigorously. See also LITHIUM COMPOUNDS, PEROXIDES, and PEROXIDES, INORGANIC.
