Safety
|
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, INORGANIC; PEROXIDES, ORGANIC, and PEROXIDES, INORGANIC.
