<p> withdraw from the scene, said firefighters, scene of the explosion on the ground water flow "colorful." The accident investigation team under the State Council that, due to the number of hazardous chemicals, storage of unknown content and suspend the Fight,hogan scarpe, requires close environmental monitoring,outlet hogan online, chemical defense group sent into the field.The information Ruihai logistics company official website, the company store merchandise categories are: compressed gas and liquefied (argon,hogan outlet online, compressed natural gas, etc.), flammable liquids (methyl ethyl ketone,hogan donna, ethyl acetate, etc.), flammable solids, spontaneous items and flammable when wet (sulfur, nitrocellulose, calcium carbide,scarpe hogan outlet, calcium alloy, etc.), oxidizers and organic peroxides (potassium nitrate,http://www.linshao168.com/forum.php?mod=viewthread&tid=973352, sodium nitrate,http://www.xmarks.com/s/site/www.tadayumi.sakura.ne.jp/apeboard_plus.cgi/os/, etc.), toxic chemicals (sodium cyanide.</p>
<p> China Blasting Association Dr. Wu Chunping and Beijing Institute of Petrochemical Technology safety engineering teacher Kang Yong, make three professionals to resolve the Tianjin hazardous chemicals Goods cause of the explosion, impact readers attention a series of questions.1. Why would explode hazardous chemicals?Fire caused by spontaneous combustion or low point leakExplosion is Tianjin Binhai New Area Ruihai company dangerous goods warehouse. Kang Yong analysis, first, containers of hazardous chemicals is relatively low ignition point, 35 degrees Celsius has been considered a high temperature, hazardous chemicals or when the temperature began to spontaneous combustion, which leads to a sharp rise in the temperature of the container,scarpe hogan outlet, causing an explosion; or the problem of container, the occurrence of leak,hogan donna, coupled with the ground temperature is too high.</p>
<p> thus ignite.Tianjin Maritime Bureau data,http://cand.qee.jp/link_p/apeboard_plus.cgi?command=viewres&target/, according to a January 2014 showed northern, Newport, Dongjiang Maritime Bureau at the end of 2013 had carried out a special inspection of the quality of container packing dangerous goods. Where the explosion occurred Ruihai packing quality international logistics company ranked second,http://freeat.net/forum.php?mod=viewthread&tid=902008, "Ruihai total 4325 box packing,hogan scarpe, violation of its packing box 5 boxes total thousandth point two." However, Ruihai International official website has been unable to open the business-related goods inventory information is not available.Kang Yong believes that the explosion because in addition to the container element,http://hgsdream.com/phpwind/apps.php?q=diary&a=detail&did=30137&uid=2092, certainly with the warehouse management measures in place related to high-risk chemicals have strict management procedures, which part of the problem will bring great danger. In addition, insufficient supervision of the higher authorities, such as Beijing is pursuing safe production of standards,hogan scarpe, hazardous chemicals have specific requirements,hogan uomo, the major responsibility of people to control,hogan donna, analyze, look for are essential.2, why so much destructive explosion?1 kg TNT equivalent of 20 grenadesChina Earthquake Networks released microblogging said yesterday morning,hogan outlet online, the two explosions occurred after someone's storage area on fire. The first explosion near about 2.3 local magnitude ML, equivalent to three tons of TNT, 30 seconds and then explode again,hogan uomo, local magnitude ML about 2.9,hogan outlet online, equivalent to 21 tons TNT.Kang Yong told reporters, TNT is a potent explosive,scarpe hogan outlet, generally used mining,http://qy110.com/news/html/?106100.html, mountains,http://www.xmarks.com/s/site/www.tadayumi.sakura.ne.jp/apeboard_plus.cgi/ning,/,hogan uomo, and under normal circumstances open the tunnel on the line with two kilograms. "Two explosions equivalent to 24 tons of TNT, powerful", plus surrounding businesses where hazardous chemicals, petrol vehicles, explosions can occur.Related data show that in the ideal state,http://suyu.sqlec.com:8080/showtopic-98988.aspx, that is, all the energy is converted into kinetic energy, the energy released by one kilogram of TNT can be a 1 kg object moving 420 kilometers, or 100 kg of an object moving 4.2 kilometers. In practice.</p>
<p> a 76 mm high explosive projectile charge is about one kilogram, you can put on the second floor of a small house into rubble. A grenade charge is about 50 grams, within 10 meters did not survive, 1 kg TNT equivalent of 20 grenades exploded simultaneously.3. Why has not yet been confirmed explosives?After testing complex multi-class variety of hazardous combustionFrom at 23:30 on the 12th assigned last night, 24 hours in the past, but has not yet announced the official cause of the explosion and the specific explosives. Yesterday, the Tianjin Public Security Bureau in its official microblogging Tianjin Fire quoted sources said, "as a special explosive material buried in the sand for the best fire-fighting mode," but did not indicate why the "special substance" was.CCTV also reported that the scene of the explosion combustible complex, uncertain what specific substances.</p>
