Acrylonitrile is reduced from "highly toxic dangerous products" to "general crisis products"
Acrylonitrile is an important organic chemical raw material, which has a prominent position in synthetic resin, synthetic fiber, synthetic rubber and other high polymer materials. Acrylonitrile is used as raw material to produce acrylonitrile fiber, NBR, acrylonitrile-butadiene - styrene resin (ABS) and styrene - acrylic resin (SAN). But acrylonitrile belong to dangerous chemicals, and possesses the characteristics of inflammable, explosive, high corrosion and to the respiratory tract, the digestive tract and skin absorption, and lead to respiratory metabolism is blocked and suffocation death, such as safety, public security and traffic administrative department of the production, marketing, transportation and storage link all have strict requirements, such as transportation, in particular, if there is an accident, to transport personnel, equipment, environment caused serious damage, so the transportation of hazardous chemicals storage safety management is very important. With the rapid development of industry economy, the domestic demand for chemicals with obvious growth, in recent years our country acrylonitrile production output is also on the rise, there are data show that in 2015 China can reach 1.56 million tons of acrylonitrile production, new capacity of 520000 tons, 18.8% growth year on year. With the further expansion of acrylonitrile production and production capacity, its safety supervision in the fields of storage, transportation and trade is also valued by relevant departments. In accordance with the "regulations on the safety management of dangerous chemicals" (state council order no. 591) concerned regulation, safety supervision bureau jointly with the ministry of industry and information technology, the ministry of public security, environmental protection department, the ministry of transport, ministry of agriculture, state health and family planning commission, quality supervision, inspection and quarantine, railway, civil aviation administration of dangerous chemicals directory (2015 edition), and May 1 in 2015, the catalog shows acrylonitrile from "virulent for" for "for", but by the ministry of transport, environmental protection department, the ministry of industry and information technology, safety supervision bureau of the catalogue of inland waterway embargo of dangerous chemicals (2015 version) "(trial) were published on August 25, 2015 as of the date of implementation of acrylonitrile continued to included in the scope of inland waterway embargo. International scope, including the dangerous goods transport experts at the United Nations commission on "sample proposal about dangerous goods regulations", "international maritime dangerous goods regulations", "international inland waterway dangerous goods transportation agreement in Europe and the United States federal statute book and other international transport laws are water transportation of acrylonitrile made very detailed, the strict rules. Acrylonitrile is an explosive mixture of flammable liquids and air. Acrylonitrile, mainly focus on the ground or floating on the surface of the water, or formation of poisonous steam and wind to spread along the ground, such as improper disposal, cause severe environmental pollution, and have spread rapidly, the characteristics of social harmfulness is big. Ever seen in my home, acrylonitrile leaked danger: in March 2003, tianjin wu qing acrylonitrile leak accident, the accident occurred near to a crowded area, fish culture zones, afterwards, the survey found that the leak nearby drainage caused serious pollution. Is also considering the risk characteristics of acrylonitrile, to human body and the harm of water environment and the difficulty of eliminating harmful consequences, could have on people's property security, the public environmental protection, the impact of the in the newly issued "the inland disable directory of dangerous chemicals (2015 version), acrylonitrile were included in the scope of inland waterway embargo. In 2015, the ministry of transport in our country to strengthen the Yangtze river and other inland water traffic safety work has carried on the detailed deployment, again will strictly the engaged in inland waterway dangerous goods transport enterprise market access, rein for ship capacity, speed up the update for ship out, establish mechanism, carry out lifelong responsibility system for ship inspection. In fact, as early as 2005 I national traffic department issued the law of the People's Republic of China on prevention and control of pollution by vessels in inland water environment management stipulation ", published in 2015, the new environmental laws, and further increase in drinking water source protection management and penalties. Along with the east route of south-to-north water transfer project construction, the inland river ships on the water environment pollution has caused the great attention of the governments at all levels, strengthen inland waterway vessel pollution control work be priority or survey department. The use of vessels to carry hazardous chemicals will not only destroy the ecology of inland waters, but also pollute the water of life and make the local environment worse. In inland ship pollution prevention work, in view of the oil products and chemical transportation port, inland river ships without useless oil removal of emergency equipment library, so in case of hazardous chemicals leakage, cannot be executed immediately response, no chemical leak emergency handler and processing ability, can cause environmental harm. As with all industrialized countries, China is now becoming more and more environmentally responsible as the reform and opening up and industrialization develop rapidly. To change this situation, we must develop circular economy, take sustainable development path, and coordinate economic development with environmental protection. As illustrated above, comprehensive consideration of water resources, environment and other factors, such as shipping, carefully treat chemical transport of dangerous goods, especially of inland water transport safety management work, a balance in the environmental protection and economic development, will be on the way of sustainable development more walk more good.
