Perhaps people remember Romania filming the "explosion" of this film? Big bang a few cases of ammonium nitrate in the movie reallycan be comparable with the atomic bomb, the explosion, shock wave and a shiver all over though not cold damage. Let us reviewa few shots.
Early on the morning of April 6, 1947, the United States of Texascity harbor a quiet, most of the crew is everything in good order and well arranged to ammonium nitrate to cargo shipment, plan to france. 8:30, who suddenly found the bottom compartmentsomehow from the black smoke, fire accident. The crew closed thehatch in the captain's orders, then the crew to evacuate to the dock. 9:15, the ship like the atomic bomb to explode, a mushroom cloud the sky, the ship was blown to smithereens. The power of the explosion set off 10 feet high tide, fire unexpectedly wharfarea water drained, far outside 5000 feet of the building with rows.The accident resulted in 570 people were killed, 3000 injured, loss of $about 50000000.
After less than ten days (April 16, 1947), a ship from the FrenchOpen, and is equipped with ten thousand tons of ammonium nitrate in the United States -- Texas freighter Xiji called chemicalcity on the Gulf of explosion, the city was nearly destroyed. At first,the crew found the cabin out of thin smoke, then black, then an emergency fire, but the fire invalid, it soared. When the firemen arrived, and ten water cannons and shot would be of no avail.Combustion in less than 40 minutes, only to hear a loud noise, a huge mushroom cloud rising in the sky, burning and collapsingstrong shock wave makes the size of buildings, a large number ofpeople were buried. The fire burned for three days and nights, 2/3blocks in ruins, three fourths of chemical enterprises to be ruined.The explosion killed 468 people, injured too many to count, the city fire escape. Afterwards, a serious investigation investigation team set up the United States government to this accident, the conclusion that all people be struck dumb; fire and explosionaccident was one of the crew inadvertently put a unburned outcigarette butts thrown into the cabin caused.
Three months later (July 28, 1947), one from the United States to France Brest port "Linaerji" also because of the explosion of ammonium nitrate and the bottom of the sea, the boat crews were killed, the accident caused more than 100 deaths, thousands ofpeople were injured.
These living scenes and indeed shocking, so the reason where?Is that our understanding of ammonium nitrate is not enough, take preventive measures ineffective, especially fire early warning work to keep up, and after the fire fighting experience, take the steameffect is not extinguishing measures, resulting in fire command the decision error, thus causing a scene human tragedy.
However, one does not become a guide for the future, in today's science and technology more advanced age, this kind of accidenthas occurred frequently, we overseas not said, only 90 time of our country has three ammonium nitrate with the influence of combustion and explosion, alarming!
In August 5, 1993, a big explosion happened in Shenzhen City,Qingshui River dangerous goods warehouse, the cause is mixedvarious chemicals warehouse, there are lots of ammonium nitrate.Because of the hot weather, the ammonium nitrate is mixed with other chemicals after the reaction heat spontaneous combustion,resulting in the explosion. The accident caused a direct economic loss of 240000000 yuan, more than 800 personnel casualties.
Early on the morning of June 23, 1994, Tianjin City Bureau metallurgical aluminum factory in the heating process ofammonium nitrate, because of not strictly in accordance with thesafety operation procedures, resulting in ammonium nitrate pool in the explosion, and most of the buildings adjacent to the factorywas destroyed, resulting in 10 deaths, 23 people were injured.
In July 28, 1994 the middle-aged, a fertilizer plant in Pengxi County, Sichuan due to mismanagement, 4 children with behind the factory ammonium nitrate warehouse, the warehouseventilation holes to the stove ignition fish to eat, the flames from the ventilation hole ignited the shutter, and then ignitedammonium nitrate in the warehouse. Fortunately because of people's fighting, ammonium nitrate no explosion occurred, but a major shock the casualty accidents; to fire people because the only fire and not wearing protective supplies, resulting in 147 people poisoning rescue of be in hospital, 3 people died.
People can not help but ask: ammonium nitrate for what? Why is itdangerous so much? Let us opened its mysterious veil, have a look the true face of Mount Lu!
Ammonium nitrate is a high nitrogen fertilizer, usually white solid,when it contains various impurities, the color will change in gray to brown. It is soluble in water and ethanol, methanol, once dissolvedwater, can absorb a large amount of heat and the temperature is reduced, when ammonium nitrate content in 3% above, it is difficult to combustion or explosion. Ammonium nitrate is aninorganic oxide, can be used to make explosives. At high temperature, ammonium nitrate can be different ways todecompose, simultaneously emit ammonia and toxic compounds of N2O, NO, NO2 etc.. Because of the collision and other reasons,the local ammonium nitrate temperature to 300 ℃, it may cause an explosion. Ammonium nitrate with any flammable liquid, a lot ofpowdered metal especially aluminum, as well as any combustible solid form explosive mixture of strong. For example, ammonium nitrate and phosphorus, sulfur, reducing agent after mixing with,can emit red brown nitrogen gas and oxygen, extremely easy to cause combustion and explosion.
