Ammonium nitrate is used commonly in fertilizers; in pyrotechniques, herbicides, and insecticides; and in the manufacture of nitrous oxide. ammonium nitrate and ensure that the conditions that may lead to an explosion are not present. In most jurisdictions, ammonium nitrate need not be classified as an explosive for transport purposes; it is merely an oxidizer. Coated Grade Prills Ammonium Nitrate PPAN LDAN NH4NO3 for Explosives in Mine 1 Coated Grade Prills Ammonium Nitrate PPAN LDAN NH4NO3 for Explosives in Mine 2 Purity:99.6% NH4NO3,34.6% N 3 IMDG Class:5.1 Class 4 UN No. It is used as a fertilizer, as a freezing mixture, in safety explosives, matches, and pyrotechnics. Triaminotoluene(TAT)vs. trinitrotoluene (TNT). It is not explosive. It is predominantly used in agriculture as a high-nitrogen fertilizer. Employees of those with licenses to deal with the substance are still required to be supervised by authorized personnel and are required to pass a security and national police check before a license may be granted. An aerial view shows the massive damage at Beirut port's grain silos and the surrounding area on August 5, 2020, one day after a massive explosion hit the heart of the Lebanese capital. Bags containing ammonium nitrate fertilizer are dispalyed in an agricultural trader in Vieillevigne, France, October 7, 2016. By comparing the blasts size against nearby buildings, video of the Beirut incident shows that in the eighth of a second after the explosion occurred, its spherical shockwave grew to roughly 800 feet wide. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures with phosphorus, tin (II) chloride or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. When they are opened (either manually or automatically by exposure to water the vests inflate rapidly. A number of crystalline phases of ammonium nitrate have been observed. Given the reported amount, Oxley hypothesizes that a vehicle must have been used to carry the compound inside, and that could have contaminated it with oil or gasoline. Agriculturists love using ammonium nitrate since it is a cheap alternative to expensive fertilizers. Fertilizer-grade prills are usually coated to reduce hygroscopicity. Pentaerythritol vs.PentaerythritolTetranitrate(PETN). Some internet rumors speculate that because the ammonium nitrate was left to sit in a warehouse for several years, it would have degraded, becoming more volatile and increasingly dangerous over time. Difficult to explode by shock. It is actually sold in the form of pellets that are coated with clay. ammonium nitrate and ensure that the conditions that may lead to an explosion are not present. Another interesting fact about this compound is that it is actually hygroscopic. In 2021, King Abdullah University of Science and Technology in Saudi Arabia conducted experiments to study the potential for dissolving ammonium nitrate in water for off-grid cooling systems and as a refrigerant. The ensuing explosion killed some 600 people, including everyone on the dock and ship. It is also used in explosives (especially as . Oxidizers do the opposite: They increase the amount of oxygen molecules that concentrate in a space, which helps make other substances more flammable. In November 2009, the government of the North West Frontier Province (NWFP) of Pakistan imposed a ban on ammonium sulfate, ammonium nitrate, and calcium ammonium nitrate fertilizers in the former Malakand Division comprising the Upper Dir, Lower Dir, Swat, Chitral, and Malakand districts of the NWFP following reports that those chemicals were used by militants to make explosives. Heating also poses a danger: ammonium nitrate decomposes at around 230C, and can explode when heated to between 260-300C if it's confined. Its melting point is at 169.6 degrees Celsius or 337.3 degrees Fahrenheit. Blending ammonium nitrate with certain other fertilizers can lower the critical relative humidity.[30]. ACSH does not have an endowment. Ammonium nitrate is an odourless material, which is usually granulated (if a fertiliser) and white in appearance. Ammonium nitrate would only explode on its own if its temperature was rapidly raised to 400 degrees Fahrenheit. [12] See Disasters for details. The chemicals reportedly have been sitting by the docks since 2013. Office of Response and Restoration, Reconstructing exactly what went wrong in Beirut will be difficult, but Chavez says officials should look for evidence of improper storage, confinement, contamination, lack of ventilation, and potential sources of ignition. Can we do it again? [18], It was once used, in combination with independently explosive "fuels" such as guanidine nitrate,[19][20] as a cheaper (but less stable) alternative to 5-aminotetrazole in the inflators of airbags manufactured by Takata Corporation, which were recalled as unsafe after killing 14 people. If the ammonium nitrate in Beirut was stored in wooden or cardboard containers, it would have made the substance incredibly flammable, says Jimmie Oxley, a chemist at the University of Rhode Island. If the name sounds familiar it's because the chemical is notorious. Ammonium nitrate provides both, intimately associated in each molecule. Ether (diethyl ether) is one of the most common organic solvents used in labs. One practical consequence of this is that ammonium nitrate cannot be used as a solid rocket motor propellant, as it develops cracks. Readily explodes if heated. Ammonium nitrate is not hazardous to health and is usually used in fertilizer products.[33][34][35]. It comes in a metal can with a label on whichyou need to write the date the bottle was first opened. It is a white crystalline salt consisting of ions of ammonium and nitrate. Ammonia is used in its anhydrous form (a gas) and the nitric acid is concentrated. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices. Use caution: Liquids with this reactive group classification have been Are "Low Dose" Health Effects of Chemicals Real? In some ways, ammonium nitrate is the perfect explosive. 2. Accident Investigation Report Solid ammonium nitrate decomposes on heating. When a single molecule ofammonium nitrate decomposes it gives up 3.5 molecules of gas (1). While ammonium nitrate is stable at ambient temperature and pressure under many conditions, it may detonate from a strong initiation charge. It also has three nitro groups, which areitching to escape as carbon monoxide, nitrogen, and water. NITRATE OF AMMONIA EXPLOSIVE is a powdered high explosive. The shipment was eventually abandoned, and its cargo moved into the hangar where it remained, despite Lebanese custom officials requesting its disposal on at least six different occasions, according to The New York Times. The S.S. Grandcampcarrying ammonium nitrate, fuel, and ammunitionarrived at the Houston-area port with smoke spewing from its cargo hold. Other health issues, akin to those seen after 9/11, may emerge given the widespread destruction to buildings and roads. Ammonium Nitrate Rules 2012 | Petroleum & Explosive Safety Organisation. There are also longer-term effects to consider. Cell phone videos also show the shockwave and dust cloud rushing through the portside buildings, leaving behind scenes of carnage in the Lebanese capital. For the word puzzle clue of an explosion caused by unsafely stored ammonium nitrate kills at least 218 people injures thousands and severely damages the port in beirut lebanon, the Sporcle Puzzle Library found the following results.Explore more crossword clues and answers by clicking on the results or quizzes. Blast calculations suggest that at sea level, an explosion like Beiruts would require about 1,000 tons of ammonium nitrate. It contains no carbon -only nitrogen, hydrogen, and oxygen. Why DACAand Dreamersare forever in a state of limbo. If stores of AN are located within the sympathetic detonation distance of explosives or blasting agents, one-half the mass of the AN is to be included in the mass . A hygroscopic substance is something that can easily collect water molecules from the environment where it is placed. Ammonal is an explosive made up of ammonium nitrate and aluminium powder, not to be confused with T-ammonal which contains trinitrotoluene as well to increase properties such as brisance. Task 1 - Structure and bonding in ammonium nitrate Molten ammonium nitrate is very sensitive to shock and detonation, particularly if it becomes contaminated with incompatible materials such as combustibles, flammable liquids, acids, chlorates, chlorides, sulfur, metals, charcoal and sawdust. The ammonium nitrate functions as an oxidizer and the aluminium as fuel. Piling up large amounts of ammonium nitrate allows more heat to be contained for longer when a mixture burns. 1:550 1956]. "The chemistry behind the Beirut explosion", "Advances in phase stabilization techniques of AN using KDN and other chemical compounds for preparing green oxidizers", "Nutrient Content of Fertilizer Materials", "Afghan bomb makers shifting to new explosives for IEDs", "Sunlight and salt water join forces in electricity-free cooling system", Airbag Compound Has Vexed Takata for Years. The substance is classified as an oxidising agent Class 5.1 (UN1942). After the solution is formed, typically at about 83% concentration, the excess water is evaporated off to leave an ammonium nitrate (AN) content of 95% to 99.9% concentration (AN melt), depending on grade. Estimating the yield from an ammonium nitrate explosion can be non-trivial. The huge change in phase creates a shockwave.. Ammonium nitrate, by itself, is not considered to be a donor when applying this table. [37] Large stockpiles of the material can also be a major fire risk due to their supporting oxidation, a situation which can easily escalate to detonation. These animals need to be able to move to survive., Why deforestation mattersand what we can do to stop it, Video Story, Copyright 1996-2015 National Geographic Society, Copyright 2015-2022 National Geographic Partners, LLC. This makes it a scaryexplosive. Capable of detonation or explosive decomposition or explosive reaction but requires a strong initiating source or must be heated under confinement before initiation. Contamination can reduce this to 20 atmospheres. Ammonium nitrate was said to be developed Germans which they used as fertilizers instead of Chilean Nitrates since it is a lot cheaper. Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse.

What happens if the flu and RSV fuse into a single virus? Should You Worry About Artificial Sweeteners? A Cheaper Airbag, and Takata's Road to a Deadly Crisis. What happens when you mix ammonium nitrate and water? Injuries surpassed more than 5,000; the blast destroyed 500 homes and the smoke from it billowed for days. It's no accident that ammonium nitrate is an explosive; it has much in common with other well-known explosive chemicals: A large number of nitrogen and oxygen atoms and a small number of carbon atoms. Pure ammonium nitrate (NH4NO3) is a white, water-soluble, crystalline substance with a melting point of 170C. Along with qualitative information, this report include the quantitative analysis of various segments in terms of market share, growth, opportunity analysis, market value, etc. It is common to use this material in agriculture and . MINISTRY OF COMMERCE AND INDUSTRY. So, without going into thermodynamics (neither of us wants this) the take-home message here is that when a lot of gas is released quickly from a molecule packed with it bad things happen. Triacetone triperoxidebelongs to a class of compounds called organic peroxides. Ammonium nitrate decomposes, non-explosively, into the gases nitrous oxide and water vapor when heated. - A A + A. Because of this reason, ammonium nitrates should not be stored in humid areas since water can easily affect the compounds explosive function. It should not be heated in a confined space. By contrast, the atomic bomb dropped on Hiroshima, Japan, in 1945 had a yield of at least 13,000 tons of TNT. This one is no exception; its nickname, Mother of Satan," is well-deserved. Stabilized ammonium nitrate (PSAN) was developed as a solution to this and incorporates metal halides stabilisers, which prevent density fluctuations.[14]. It's no accident that ammonium nitrate is an explosive; it has much in common with other well-knownexplosive chemicals: Those trapped gases are none too happy about being crammed together in a little molecule. It requires a. Once the bottle is opened the ether is exposed to oxygen and it slowly forms explosivehydroperoxides. The primary reaction when it breaks down produces nitrogen, water vapour and oxygen. National Oceanic and Atmospheric Administration. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere. The potential for use of the material as an explosive has prompted regulatory measures. Belongs to the Following Reactive Group(s). Where Have All the Public Health Leaders Gone? Seventy-five years later, National Geographic revisits the elusive horror of Hiroshima. People helped them reboundbut recent die-offs are a worrying sign. Aside from that, ammonium nitrate is also the main component of an explosive called ANFO which stands for Ammonium Nitrate Fuel Oil. Director of Chemical and Pharmaceutical Science. Ammonium nitrate was mined there until the HaberBosch process made it possible to synthesize nitrates from atmospheric nitrogen, thus rendering nitrate mining obsolete. We may be getting closer. But David Chavez, an explosives scientist at the Los Alamos National Laboratory in New Mexico, doubts that scenario. Sometimes just opening the bottle can set off an explosionThis is whybottles of ether older than 6 months must be discarded. Lower Explosive Limit (LEL): data unavailable, Upper Explosive Limit (UEL): data unavailable, Autoignition Temperature: data unavailable, Vapor Density (Relative to Air): data unavailable, Ionization Energy/Potential: data unavailable.

Lebanon was already dealing with political and financial woes, due in part to the Syrian migration crisis and the coronavirus pandemic. Decades ago, extinction loomed for these gentle marine mammals in Florida. 1. Or, this discrepancy might mean that the material inside the warehouse was not pure ammonium nitrate, and some other compound was involved with the blast. We raise our funds each year primarily from individuals and foundations. No sir, they want their freedom and it can take a very small nudge, physical or chemical, to grant them their wish. It should not be stored near high explosives or blasting agents. [6] Accidental ammonium nitrate explosions have killed thousands of people since the early 20th century.[6]. Why Do Books Smell?

When something burns, it requires oxygenthats why fire extinguishers can easily put out flames by smothering them. It is an inorganic molecular entity, an ammonium salt and an inorganic nitrate salt. Both decomposition reactions are exothermic and their products are gas. [27][22], Contact with certain substances such as chlorates, mineral acids and metal sulfides, can lead to vigorous or even violent decomposition capable of igniting nearby combustible material or detonating. The transition between -rhombic to -rhombic forms (at 32.3C) occurs at ambient temperature in many parts of the world. absorbents These prills or granules are the typical AN products in commerce. In April 1995, American terrorists Timothy McVeigh and Terry Nichols used two tons of the compound in a truck-bomb attack on the Oklahoma City federal building; 168 people were killed. No hazard beyond that of ordinary combustible material. This is the reason for the orange cloud. A large explosion rocked the Lebanese capital Beirut on August 4. It also destroyed Texas City in 1947 and the Alfred P. Murrah Federal Building in Oklahoma City in 1995. Ans. Such investigations may take time. "If the pictures are right, this was something meant to be an oxidizer used with other agents," such as explosives used for mining, he says. Another production method is a variant of the nitrophosphate process: The products, calcium carbonate and ammonium nitrate, may be separately purified or sold combined as calcium ammonium nitrate. Toxic nitrogen oxide fumes may be released during combustion. When heated it is only too happy to give them up. Many aspects of this 'runaway' reaction can be explained by concepts such as enthalpy change and by taking a closer look at the structure and bonding of ammonium nitrate. It is a strong oxidizing agent. Add enough of the oxidizer to a fire, and it will trigger an explosion. [22][25][26] It should not be stored near combustible substances. [16]:2. In room temperature, ammonium nitrate appears in a white crystalline form and it is also colorless. It is composed of nitric acid and salt of ammonia. However, the source of ammonium nitrate used for improvised explosive mixtures is often fertilizer. (Seventy-five years later, National Geographic revisits the elusive horror of Hiroshima.). And just five years ago, an estimated 800 tons of ammonium nitrate fueled a warehouse explosion that leveled part of a port in the Chinese city of Tianjin, killing 173. The industry made famous in 'Tiger King' to be banned, A rare look at the worlds most expensive sheep. No rapid reaction with water. Ants make milk? [16]:1 It is used in coal mining, quarrying, metal mining, and civil construction in undemanding applications where the advantages of ANFO's low cost, relative safety, and ease of use matter more than the benefits offered by conventional industrial explosives, such as water resistance, oxygen balance, high detonation velocity, and performance in small diameters. Answer (1 of 13): High explosives all generally share one trait, easy access to a strong oxidizer. It has a role as a fertilizer, an explosive and an oxidising agent. Explosives - ANFO (Ammonium Nitrate - Fuel Oil) On 10 November 2009 International troops and Afghan police seized 250 tons of ammonium nitrate fertilizer in the southern city of Kandahar.. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures with phosphorus, tin(II) chloride or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. USA.gov. Sunflowers make bees poopa lot. A mixture of ammonium nitrate and aluminum powder (also zinc, cadmium, copper, magnesium, lead, cobalt, nickel, bismuth, chromium, and antimony behave similarly to aluminum) can be used as an explosive. It is used as an absorbent for nitrogen oxides, an ingredient of freezing mixtures, an oxidizer in rocket propellants, and a nutrient for yeast and antibiotics. Fertilizer-grade ammonium nitrate can be powdered or in the form of prills. Though Lebanese authorities have said ammonium nitrate was the culprit in the blast, Lewis notes that in many cases commercial explosives are referred to as just this compound even though they contain additives. Pentaerythritol, a common chemical intermediate for the production of plastics, paints, and cosmetics. These trips help you embrace itor escape it. NH4NO3 (s) -------> N2 (g) + 2H2O (g)+ 1/2 O2 (g). But for the compound to figure in an explosion of this magnitude, chemists and explosives experts say a lot has to go wrong. Ammonium nitrate readily forms explosive mixtures with varying properties when combined with explosives such as TNT or with fuels like aluminum powder or fuel oil. This fertilizer is a powerful oxidizer, with the additional complexity that it can release heat when it decomposes (i.e., exothermic decomposition) and becomes an explosive when it mixes with an organic fuel. Ammonium nitrate is sensitive to heat and any application of this external factor can lead to explosion. How do you kill hard-to-reach tumors? Annually, the world produces and stores enormous amounts of ammonium nitratemore than 20 million tons in 2017. They suggested that the water could be distilled and reused using solar energy to avoid water wastage in severe environments. ANFO is composed of 94 percent ammonium nitrate and 6 percent fuel oil. Chemically, it's not at all surprising that ammonium nitrate can detonate. The kind of ammonium nitrate sold in the market contains an average of 33.5 percent of nitrogen. Theres a massive amount of energy given off very quickly, says Stephen Beaudoin, a chemical engineer also at Purdue University. The blast, which rattled entire buildings and broke glass, was felt across the city. Using math pioneered in the 1940s to infer the atomic bombs yield, experts can analyze videos of a shockwave to get rough estimates of an explosions total energy and how much material blew up. In the Know with 'Dr. Examples of explosives containing ammonium nitrate include: ANFO is a mixture of 94% ammonium nitrate ("AN") and 6% fuel oil ("FO") widely used as a bulk industrial explosive. Ammonium nitrate can also be made via metathesis reactions: As ammonium nitrate is a salt, both the cation, NH4+, and the anion, NO3, may take part in chemical reactions. Ammonium nitrate has an LD50 of 2217mg/kg,[36] which for comparison is about two-thirds that of table salt. Unauthorized use is prohibited. Compared to most combustible materials, ammonium nitrate itself is not exceptionally explosive. Otherwise, it can coalesce into a large, solid mass. Nearly all women suffer from hot flashes during menopause. This mixture (ANFO) has become popular in bomb making. How do you prevent ammonium nitrate from exploding? You shouldsee a pattern. But the compound can contribute to explosions because it belongs to a chemical class known as oxidizers. . NH4NO3, ammonium ni. The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid:[10]. All rights reserved, math pioneered in the 1940s to infer the atomic bombs yield. A deep-dive into the chemistry and legacy of the compound offers clues into what sparked Lebanons catastrophe. Therefore, it is important to store ammonium nitrate in a tightly sealed container. Dr. Josh Bloom,the Director of Chemical and Pharmaceutical Science, comes from the world of drug discovery, where he did researchfor more than 20 years. The reason why it is very popular in agriculture is because of the high nitrogen amount in this compound. More info about absorbents, including situations to watch out for National Oceanic and Atmospheric Administration. Another famous use of ammonium nitrate is as an additive in explosives. Under certain conditions, this can lead to a runaway reaction, with the decomposition process becoming explosive. In the Beirut explosion, the resulting shockwave moved faster than the speed of sound; cell phone videos show the impact washing over the city a few seconds before a sonic boom rumbles. That usually takes the form of oxygen atoms available within the HE molecules themselves, but not already bound up in high energy bonds. Ammonium Nitrate is a chemical compound with the formula NH4NO3. Ammonium nitrate is used as an oxidizing agent in explosives. These codes, which may be adopted into law at the state or local level, are: NFPA 490 Storage of Ammonium Nitrate, 1993, and NFPA 495 Explosive Materials Code, 1996. ammonium nitrate (AN), ammonium nitrate-fuel oil (ANFO) or combinations thereof are acceptors. Facts and information about ammonium nitrate. You can think of these gases as being "trapped" within the molecule. Key Largo is the pristine paradise where you wanna go, How Nessie and the Yeti birthed a global cryptid-chasing industry, Photograph by Anwar AMRO, AFP via Getty Images. Ammonium nitrate Explosives: update The UK has left the EU, and some rules and procedures have changed from 1 January 2021. Moreover, the decomposition of ammonium nitrate can create byproducts known as nitrogen oxides, which are known to cause respiratory distress. Heres why thats good. This page contains information about: the safe storage and handling. What detonated the explosive compound remains unclearbut the Beirut blast is not the first time ammonium nitrate has led to calamity. Plastics, for example, paint, and other organic materials that completely or partially burnedall the building materials that became dust., Copyright 1996-2015 National Geographic SocietyCopyright 2015-2022 National Geographic Partners, LLC. The AN melt is then made into "prills" or small beads in a spray tower, or into granules by spraying and tumbling in a rotating drum. Detonation may occur at 80 atmospheres. Size and style. It can also yield rapid growth and may increase the fruit production capacity of a plant. Now Explosive Organic Peroxides, Xenon, the 'Stranger Gas': A Dreaded Chemistry Lesson From Hell, What's the Deal with Hemoglobin A1c? Other gases, notablynitrogen dioxide, are also formed. Ammonium nitrate is a hazardous chemical that has many grades and is used in fertiliser and explosives products because of its unique properties. The commercial grade contains about 33.5 percent nitrogen, all of which is in forms utilizable by plants; it is the most common nitrogenous component of artificial fertilizers. How did this royal tomb become an ancient wonder? With that, here's the answer to the question people around the world and especially in Lebanon are asking themselves: Why does it explode?

In 1921, about 4,500 tonnes of ammonium nitrate caused an explosion at a plant in Oppau, Germany, killing more than 500 people The deadliest industrial accident in US history occurred in 1947. [22] The resulting heat and pressure from decomposition increases the sensitivity to detonation and increases the speed of decomposition. [37] Large stockpiles of the material can also be a major fire risk due to their supporting oxidation, a situation which can easily escalate to detonation. Ammonium nitrate is sensitive to heat and any application of this external factor can lead to explosion. Chemical Advisory: Safe Storage, Handling, and Management of Ammonium Nitrate, United States Environmental Protection Agency, "Report for Kooragang Island Update PHA MOD1 Report", "Guidance for Compatibility of Fertilizer Blending Materials", "Material Safety Data Sheet, Ammonium nitrate MSDS", "Lebanon's president calls for two-week state of emergency in Beirut after blast", https://en.wikipedia.org/w/index.php?title=Ammonium_nitrate&oldid=1123458676, Shock-to-detonation transition. Winter is coming. Let's take a look at some explosive chemicals. These are improvised explosive devices that other people use in terrorism. Below are details of ammonium nitrate and expert comment: * Ammonium nitrate is an industrial chemical commonly used in fertilisers and as an explosive for quarrying and mining. [1] Fortunately, he was too incompetent to ignite it. They were brought to the U.S. as childrenand for many, its the only home theyve ever known. Ammonium nitrate-based explosives were used in the Sterling Hall bombing in Madison, Wisconsin, 1970, the Oklahoma City bombing in 1995, the 2011 Delhi bombings, the 2011 bombing in Oslo, and the 2013 Hyderabad blasts. Here is the equation. You could fire it out of a bazooka and it won't do anything. The redorange colour in an explosion cloud is due to nitrogen dioxide, a secondary reaction product.[12]. He holds a Ph.D. in chemistry. Examples of such disasters are. We rallied to save manatees once. It's the chemical that Richard Reid ("The Shoe Bomber")had in his shoe in an American Airlines flight to Miami in 2001. Ammonium nitrate is a chemical compound with the formula NH4NO3. Commercially, it is prepared by mixing nitric acid and ammonia salt. The following occur under atmospheric pressure. [28][29], Ammonium nitrate begins decomposition after melting, releasing NOx, HNO3, NH3 and H2O. All kinds of other materials probably ignited and burned, says Beaudoin. Its known to predispose people to the worst effects of respiratory diseases, including COVID-19. Health and safety data are shown on the safety data sheets available from suppliers and from various governments.[22][23][24]. Its relatively difficult to make pure ammonium nitrate go off unless you add things to it and cook it in a giant fire, says Davin Piercey, a chemist at Purdue University. The MarketWatch News Department was not involved in the creation of this content. The report on Ammonium Nitrate Explosive Market offers in-depth analysis on market trends, drivers, restraints, opportunities etc. The reaction from the two substances combined will form Ammonium Nitrate. The blast registered as magnitude 3.3 on the Richter scale, and caused devastation usually associated with major earthquakes. For example, in Australia, the Dangerous Goods Regulations came into effect in August 2005 to enforce licensing in dealing with such substances. In the case of the Beirut explosion, the initial fire likely . It is an explosive mixture which is used widely in mining. Explosions are not uncommon: relatively minor incidents occur most years, and several large and devastating explosions have also occurred. Examples include the Oppau explosion of 1921 (one of the largest artificial non-nuclear explosions), the Texas City disaster of 1947, the 2015 Tianjin explosions in China, and the 2020 Beirut explosion.[38]. Web site owner: Ammonium nitrate decomposes, non-explosively, into the gases nitrous oxide and water vapor when heated. Lebanese authorities are blaming the incident on more than 2,750 metric tons of ammonium nitrate, a substance commonly used in fertilizers as well as in explosives for mining and construction projects. The mixture is often referred to as Tannerite, which is a brand of ammonal. Particle physics is on the case. Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). COPYRIGHT 1978-2022 BY THE AMERICAN COUNCIL ON SCIENCE AND HEALTH. The self-inflating life vests in airplanes work in a similar manner. Ammonium Nitrate is generally used as a fertilizer. Though ammonium nitrate was first synthesized in 1659 by German chemist Johann Rudolf Glauber, it wasnt used in explosives until World War I, when weapon makers mixed it with TNT (aka dynamite) to make cheaper bombs. TNT also contains 7 C but 9 (N + O) atoms. Given that these back-of-the-envelope calculations come with a wide margin of error, the estimate is consistent with the 2,750 tons that Lebanese officials say was stored by the port. It may also affect the quality of green leafy vegetables since the nitrogen which is used by the plants is actually very helpful in the process of photosynthesis. Ammonium nitrates are now regulated by the government since it is already used to create fertilizer bombs. Ammonium nitrate, (NH 4 NO 3), a salt of ammonia and nitric acid, used widely in fertilizers and explosives. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is a strong oxidizing agent. [15] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Please be respectful of copyright. Is it possible to cure hot flashes? [4] Global production was estimated at 21.6 million tonnes in 2017.[5]. Ammonium nitrate is the main component of slurry explosives used for mining. Even a small amount of contamination would have made the ammonium nitrate more likely to detonate. A more likely explanation is that the ammonium nitrate in Beirut was not alone inside the warehouse. [27], Ammonium nitrate has a critical relative humidity of 59.4% at 30C. known to react with the Beirut mayor Marwan Abboud told Agence France-Presse that 300,000 people are unable to return to their homes, as the damage covered half the city and could cost up to $15 billion to repair. The worlds oldest map of the night sky was amazingly accurate. Smaller (low molecular weight) organic peroxides contain a high proportion of oxygen to carbon, which makes them very dangerous. The wall of shipping containers will prevent passage for dozens of speciesincluding endangered jaguars. "[17], Ammonium nitrate is used in some instant cold packs, as its dissolution in water is highly endothermic. Joe', A Conversation Between ACSH and Great.com, Insanity: Doctor Gives Teenage Son Cigarettes to Break Vaping Habit, Underwater Suicide?
