Magnesium peroxide(Mg(O2)) (14452-57-4)

General Description: A white powder. Noncombustible but accelerates the burning of combustible material, if the combustible material is finely divided the mixture may be explosive. Mixtures of combustible material and the peroxide can be ignited by friction or contact with moisture. Used in medicine, and as a bleaching agent.
Air & Water Reactions: Insoluble in water and slowly decomposed by water, liberating oxygen.
Reactivity Profile: Mixtures of combustible material and the peroxide can be ignited with friction or moisture.
Water gradually decomposes Magnesium dioxide liberating oxygen, with dilute acids Magnesium dioxide forms hydrogen peroxide, when strongly heated Magnesium dioxide losses all peroxide oxygen.
Health Hazard :Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Fire Hazard: These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
