Never direct water jet straight at liquid ammonia. It is not considered a flammable gas but a large and intense energy source may cause ignition and/or explosion. Move containers from the fire area if … It is a COMPRESSED GAS and a confined space explosion and toxicity hazard. Lv 7. And that the combustion of ammonia in air is $$\ce{4NH3 + 3O2 -> 2N2 + 6H2O}$$ My understanding of this is that with a 20% air to $\ce{NH3}$ that I could hold a flame. I have read on Wikipedia that the flammable limits of gaseous ammonia are between 15–25% and I have also read that the autoignition temperature is $651\rm~^\circ C$. Sign in. Ammonia gas is a CORROSIVE GAS and may be fatal if inhaled. Ammonia gas can decompose at high temperatures forming very flammable hydrogen and toxic nitrogen dioxide. Ammonia gas is non-flammable, but because at certain concentrations when mixed with air it could explode if ignited, it is treated as flammable. There is an extensive history of catastrophic releases of NH(3) in the nations workplaces resulting in … It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. For small fires use dry chemical or carbon dioxide. Synonym :ammonia; anhydrous ammonia SDS # :001003 Airgas USA, LLC and its affiliates 259 North Radnor-Chester Road Suite 100 Radnor, PA 19087-5283 1-610-687-5253 24-hour telephone :1-866-734-3438 Section 2. A similar procedure was adopted for measurements at elevated temperatures except that the ammonia/ oxygen/nitrogen mixtures were prepared in a heated 6 litre stainless steel bomb at above You can sign in to give your opinion on the answer. Ammonia gas can decompose at high temperatures forming very flammable hydrogen and toxic nitrogen dioxide. Ammonia can be explosive, especially in an enclosed space or when other flammable chemicals are present. [Note: Shipped as a liquefied compressed gas. When mixed with lubricating oils, the flammable range increases. One concern is that ammonia is toxic and flammable. What do you think of the answers? The National Fire Protection Association (NFPA) rates anhydrous ammonia as a 3 (on a scale of 4) - a most severe toxic health hazard and as a 1 (on a scale of 4) - a flammable gas. • Ammonia is usually shipped as a compressed liquid in steel containers. Colorless gas with a pungent, suffocating odor. Fire will produce irritating, corrosive, and/or toxic gases. Chemical name :ammonia Supplier's details : Ammonia Product use :Synthetic/Analytical chemistry. Old Science Guy. Ammonia is flammable - a tank which previously held ammonia exploded killing a man when he cut into the tank with a gas torch. For large fires use water spray, fog, or regular foam. 0 0. 1 decade ago. • Ammonia gas is easily compressed and forms a clear liquid under pressure. • Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base. • Ammonia is not highly flammable, but containers of ammonia may explode when Ammonia will react dangerously with some chemicals—most notably, chlorine bleach. By itself, its flammable range is between 15 percent and 28 percent by volume in air.
