A fire was detected on the Finnish cargo ship Tirrenia on 23 January 1953, while it was carrying ammonium nitrate. Attempts to extinguish the fire with steam were unsuccessful, and the ship was abandoned before it exploded later in the night. [11] United States Roseburg, Oregon 7 August 1959: 14 4.1
Fire: Not combustible itself but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may accelerate burning. Explosion: No danger of explosion. KNO 3 is an oxidising agent, so will accelerate combustion of combustibles. Fire Extinguishing Media: Dry chemical, carbon dioxide, Halon, water spray, or fog ...
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
NO y is the class of compounds comprising NO x and the NO z compounds produced from the oxidation of NO x which include nitric acid, nitrous acid (HONO), dinitrogen pentoxide (N 2 O 5), peroxyacetyl nitrate (PAN), alkyl nitrates (RONO 2), peroxyalkyl nitrates (ROONO 2), the nitrate radical (NO 3), and peroxynitric acid (HNO 4).
This fire engine, used by the Toronto Fire Services, is an example of firefighting apparatus. A firefighting apparatus (North American English) [1] or firefighting appliance (UK English) [2] describes any vehicle that has been customized for use during firefighting operations.
Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.
The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.
A reducing flame is a flame with insufficient oxygen. It has an opaque yellow or orange color due to carbon or hydrocarbons [3] which bind with (or reduce) the oxygen contained in the materials the flame processes. [2]
