Lebanese officials say ammonium nitrate, a substance used as fertilizer in agriculture, likely caused the massive explosion in Beirut. Storing and handling ammonium nitrate. The explosion killed at … “I think that’s what’s happened here,” said da Silva. It is most commonly used … It is highly soluble in water; heating of the water solution decomposes the salt to nitrous oxide (laughing gas). It must be mixed with other primary explosives to form an explosive mixture. On the basis of Application, the Global Ammonium Nitrate (CAS 6484-52-2) market is segmented into: Military Grade Ammonium Nitrate. Fireworks contain perchlorate, as does rocket fuel … By Helen Regan, Tamara Qiblawi, Ghazi Balkiz, Ben Wedeman and Luke McGee, CNN. When heated it is only too happy to give them up. It is classified as an oxidiser (Grade 5.1) under the United Nations classification of dangerous goods. Industrial Grade Ammonium Nitrate The colossal explosion in Lebanon’s capital this week was apparently caused when more than 2,700 tons of ammonium nitrate detonated. Ammonium nitrate is a chemical compound with the formula NH4 NO3, and it's made by combining ammonia with nitric acid. It has a role as a fertilizer, an explosive and an oxidizing agent. Ammonium nitrate is unstable and explodes violently if it comes into contact with an open flame or another ignition source. Nitrogen in itself is very unreactive, demonstrated in the composition of our atmosphere, which is 78 percent made up of the gas. Pure ammonium nitrate is not an explosive on its own. The decomposition reaction can be summarized as There, the detonation of a 2,300 tonne stockpile of ammonium nitrate created one of the largest non-nuclear man-made explosions in history. Despite being a major component of many explosives, ammonium nitrate does not act as an explosive by itself. In its pure form, ammonium nitrate isn’t usually explosive – in fact, it’s safe to handle. Ammonium nitrate is a colourless crystalline substance (melting point 169.6 °C [337.3 °F]). The explosive force occurs when solid ammonium nitrate decomposes very rapidly into two gases, nitrous oxide and water vapor. Because solid ammonium nitrate can undergo explosive decomposition when heated in a confined space, government regulations have been imposed on its shipment and storage. Ammonium nitrate has the chemical formula NH₄NO₃. A component of fertilizer, ammonium nitrate is potentially explosive. While ammonium nitrate can in fact put out a fire, if the chemical itself is contaminated, for example with oil, it becomes highly explosive. “Ammonium nitrate is the ammonium salt of nitric acid. The … Others. An ammonium nitrate explosion produces massive amounts of nitrogen oxides. Ammonium nitrate provides both, intimately associated in each molecule. Ammonium Nitrate Compounds. Ammonium nitrate is used as an oxidizing agent in explosives. The explosive potential of ammonium nitrate is well understood and has been used in numerous terrorist attacks including the Oklahoma City bombing of 1995. On explosion, ammonium nitrate yields N 2, O 2, and water as the by-products. Produced as small porous pellets, or “prills”, it’s one of the world’s most widely used fertilisers. Ammonium nitrate is some pretty nasty stuff, and can seriously land yourself in danger’s path if you don’t know what you’re doing, so if you have to leave a comment below asking how rations, parts, and percentages work…do not try to make this stuff. Although ammonium nitrate is an important fertilizer because of its high nitrogen content, its explosive hazards limits its application, and it has even been banned in some areas. Ammonium nitrate is the fertilizer compound that can be used in explosives, said John Goodpaster, who researches explosives at Indiana at University-Purdue University Indianapolis. As ammonium nitrate is a highly explosive chemical, many countries strictly regulate its use. In some ways, ammonium nitrate is the perfect explosive. Images … Solution for Ammonium nitrate is an explosive and a fertilizer. However, if it is contaminated with impurities, the risk of it detonating increases. HSE’s leaflet INDG230 Storing and handling ammonium nitrate provides information relating to the general duties imposed on employers by the Health and Safety at Work etc Act 1974 with regard to the safe storage and handling of ammonium nitrate at, for example, harbours, merchant stores and manufacturers’ premises. It's a white solid made up entirely of gases. Perhaps the closest comparison to Beirut's explosion, in terms of scale, is a blast in Texas City in 1947, which was caused by 2,300 US tons (about 2,087 metric tons) of ammonium nitrate. This … Kauffman said, in principle, ammonium nitrate should be highly explosive by itself, but it is not. When combined with fuel oils, ammonium nitrate creates a potent explosive widely used by the construction industry, but also by insurgent groups like the Taliban for … It contains no carbon - only nitrogen, hydrogen, and oxygen. When combined with fuel oils, ammonium nitrate creates a potent explosive widely used by the construction industry, but also by insurgent groups like the Taliban for improvised explosives. Ammonium nitrate was also involved in that explosion. Once a reaction is sparked (by some other means) the ammonium nitrate quickly decomposes into… Ammonium nitrate was involved in the 1947 Texas City disaster, one of the largest industrial explosions in history.. In fact, in its base state, ammonium nitrate can put out a fire. It … Ammonium Nitrate Regulations in India A mixture of 94% porous pellets of ammonium nitrate acts as an oxidizing agent when added to fuel oil (6% of the total volume) and can be used to create a basic but deadly explosive. Ammonium nitrate stored in a warehouse linked to catastrophic Beirut explosion. Nitrogen dioxide (NO₂) is a red, bad-smelling gas. When ammonium nitrate is mixed with fuel oil an extreme exothermic reaction takes place. Over the past 100 years, there have been several disasters involving the chemical. This report segments the global Ammonium Nitrate (CAS 6484-52-2) market on the basis of types is: Fertilizers. But the chemical has a more nefarious use -- as an explosive… By itself, ammonium nitrate is not regarded as particularly volatile or dangerous, but under certain conditions it can be deadly. Heating also poses a danger: ammonium nitrate decomposes at around 230˚C, and can explode when heated to between 260–300˚C if it’s confined. Here lies yet another link to explosives: fireworks, which set off the ammonium nitrate explosion in Beirut. Ammonium nitrate has been used for centuries in warfare, but is also a mainstay of commercial nitrogenous fertilizers. It is also a key component of ANFO, (ammonium nitrate/fuel oil), an industrial explosive used in mining, quarrying, and civil construction and accounting for 80% of all the industrial explosives used in US. If mixed with ingredients like fuel or some other contaminants, or because of some other external factors, it can be very explosive. Nearby stores of … Chinese authorities claimed the first explosion had been triggered after the heat of summer caused a highly flammable compound called nitrocellulose to spontaneously catch fire. Chemical Agents. Explosives. Ammonium nitrate is an oxidiser on its own and is therefore not explosive. The explosive nature of ammonium nitrate is due to its decomposition into gaseous products (nitrogen, H 2 O vapor, and oxygen) and also due to the exothermic nature of the reaction.
