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. 0 0. When mixed with lubricating oils, the flammable range increases. • Ammonia is usually shipped as a compressed liquid in steel containers. 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 $651\rm~^\circ C$. 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. Lv 7. [Note: Shipped as a liquefied compressed gas. By itself, its flammable range is between 15 percent and 28 percent by volume in air. It is a COMPRESSED GAS and a confined space explosion and toxicity hazard. It is not considered a flammable gas but a large and intense energy source may cause ignition and/or explosion. One concern is that ammonia is toxic and flammable. • Ammonia is not highly flammable, but containers of ammonia may explode when flammable if a flame travelled away from the electrodes for the full length of the tube. Old Science Guy. 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. Never direct water jet straight at liquid ammonia. Ammonia is flammable - a tank which previously held ammonia exploded killing a man when he cut into the tank with a gas torch. Colorless gas with a pungent, suffocating odor. • Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base. For large fires use water spray, fog, or regular foam. What do you think of the answers? For small fires use dry chemical or carbon dioxide. 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 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. 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. Sign in. Ammonia gas can decompose at high temperatures forming very flammable hydrogen and toxic nitrogen dioxide. Move containers from the fire area if … Chemical name :ammonia Supplier's details : Ammonia Product use :Synthetic/Analytical chemistry. Ammonia is flammable. 1 decade ago. Ammonia will react dangerously with some chemicals—most notably, chlorine bleach. Ammonia gas is non-flammable, but because at certain concentrations when mixed with air it could explode if ignited, it is treated as flammable. Fire will produce irritating, corrosive, and/or toxic gases. • Ammonia gas is easily compressed and forms a clear liquid under pressure. You can sign in to give your opinion on the answer. Ammonia can be explosive, especially in an enclosed space or when other flammable chemicals are present. check this out. 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.
