Safety Profile
Poison by inhalation and ingestion. Narcotic in high concentrations. Lowers blood pressure. Methemoglobinemia has been reported. A very dangerous fire and severe explosion hazard when exposed to heat or flame. A powerful oxidizer. May explode when heated above 90℃. Highly dangerous when heated to decomposition or on contact with acid or acid fumes. To fight fire, use foam, CO2, dry chemical, or water spray. When heated to decomposition it emits toxic fumes of NOx. See also NITRITES and ETHERS.
