At 14:50 on March 21, a serious explosion occurred at the Tianjiayi Chemical Plant in Chenjiagang Chemical Industrial Park, Xiangshui County, Yancheng City, Jiangsu Province. The scene was full of fire and the smoke rose. A row of house windows and doors were blown up in an instant. At the scene, there were blood on the head and face. As of 7 o'clock this morning, it was confirmed that the accident had caused 44 deaths, 32 people were critically ill, 58 people were seriously injured, and some people were slightly injured. According to the production process of the plant, the accident is likely to be in the production process, due to the volatilization of flammable liquid such as benzene, and the occurrence of deflagration in the open flame, eventually detonating all kinds of organic matter.
There are several residential areas and schools near the explosion area, and at least 7 schools near the explosion area. One of the kindergartens was only 1.1 kilometers away from the scene of the incident. The explosion has caused some children to be injured. There are some controversies about the pollutants that may be leaked in this explosion, but the most likely ones are benzene, p-phenylenediamine and other harmful substances. Among them, benzene is a type of carcinogen that damages the blood and immune system and may cause genetic damage, and phenylenediamine also has strong acute toxicity. These substances may cause harm to local water sources after the leak.
The Xiangshui County Chemical Industry Park, where Jiangsu Tianjiayi Chemical Co., Ltd. is located, is located in Chenjiagang Town. The planned area of the chemical park is 10.5 square kilometers. Since 2002, it has attracted many chemical companies to settle in. However, since the establishment of the park, there have been many safety production accidents in the chemical park.
- On November 27, 2007, Jiangsu Lianhua Technology Co., Ltd. exploded in the park, causing dozens of deaths and injuries to eight people;
- On November 23, 2010, a chlorine leak occurred in Jiangsu Dahe Chlor-Alkali Chemical Company in the park, resulting in poisoning of more than 30 employees of Jiangsu Zhijiang Chemical Company.
- On May 18, 2011, a major fire broke out in the southern chemical plant in the park;
- On July 26, 2011, a major fire broke out in the Southern Chemical Plant...
Following the fires and explosions in the university laboratories in the previous period, the chemical plant was involved again. The bloody lesson once again sounded the alarm for the safety management of production and operations.
Many factories, schools, research institutes, and hospitals use or contact various types of flammable, flammable, corrosive, dangerous materials, and any negligence in any part of the production or operation process, which may cause serious accidents and cause personal injury. Property damage or environmental pollution, and seriously affect the efficiency of production and operation, resulting in immeasurable economic losses. How to carry out effective security management has become an indispensable part of daily work.
As the world's leading provider of integrated security solutions, Sisbel products cover the four major segments of storage, transfer, use and disposal of hazardous chemicals, serving chemical, electronics, automotive, pharmaceutical, food, aviation, railway, and hospitals around the world. Schools and other institutions and institutions have been unanimously recognized by users.
One of the main causes of industrial fires is the improper storage of flammable products. Fire safety cabinets help to safely store fuels, chemicals and solvents, reduce fire risks and protect people and property. The use of FM-certified safety cabinets ensures safe management and isolation of hazardous chemicals and a safe evacuation time in the event of a fire. An important factor in choosing a safety cabinet is the understanding of the nature of the stored chemicals. Steel safety cabinets are suitable for flammable liquids. For flammable but less corrosive liquids, it is recommended to use chemically resistant steel safety cabinets with polyethylene bushings. For non-flammable strong acids and corrosive products, polyethylene safety cabinets are highly resistant to chemicals and leaks, providing maximum protection.
When hazardous chemicals are transferred between different areas and containers, special safe tanks are needed to control flammable vapors to prevent possible fires and explosions. The safety tank must also be leak-proof and automatically discharge steam from 10.2 to 0.35 bar to prevent explosion or explosion in a fire. Prevent the flame from contacting the flammable liquid through the filling port. It is able to withstand damage and wear during normal use, is easy to use during filling/dumping/carrying, and is properly labeled to recognize the contents of the device. Different types of safety tanks meet the application needs of different occasions.
Reasonable disposal of hazardous waste is essential in fire prevention. When flammable liquids are contaminated, they may actually be more dangerous. The use of safe disposal tank collection enables the protection and volatilization of volatile gases, prevents accidental spillage, reliably dissipates heat and prevents flashback, and greatly improves safety and reliability. For rags impregnated with flammable liquids, they can be placed in a grease can. The specially designed oil spill waste can effectively eliminate the spontaneous combustion hazard and reduce the occurrence of fire.
