Specification
Nickel dinitrite (CAS NO.17861-62-0) is also named as Nitrous acid, nickel (2+) salt ; Nickel nitrite [UN2726] [Oxidizer] ; UN2726 . Nickel dinitrite (CAS NO.17861-62-0) is a crystalline solid or the solid dissolved in a liquid. It is slightly soluble in water. Contact may irritate skin, eyes and mucous membranes. It may be toxic by ingestion. Nickel dinitrite is noncombustible, but accelerates the burning of combustible materials. Nickel dinitrite is a strong oxidizing agent. A violent explosion occurs if an ammonium salt is melted with a nitrite salt. A mixture of potassium cyanide and nitrite salts may cause an explosion. 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. 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.
