The weather in Weibo and Shanghai.

At 4: 28 on June 18, a fire broke out in the ethylene glycol plant area of Sinopec Shanghai Petrochemical Industry Bureau in Jinshan District, Shanghai. After preliminary verification, an employee of Shanghai Petrochemical Company was slightly injured and a driver of a third-party transport vehicle died. The specific reasons are under further investigation. The live video shows that after the accident, the flame instantly flooded the whole sky, and then the smoke rose. Several loud noises also awakened many citizens in Jinshan District.

Protective combustion is to make the remaining substances burn out in a controlled way, and then carry out the next rescue work. After the fire broke out, Shanghai 1 19 Command Center quickly dispatched rescue forces such as Jinshan, Fengxian and Chemical Industry Zone to the scene to put out the fire. According to Weibo, the official of "Shanghai Petrochemical Online", the company immediately launched the first-level plan after the accident. By 9: 00 on 18, the fire was effectively controlled and protective combustion was being carried out at the scene.

China petroleum professor-level senior engineer often told China that ethylene glycol is an important chemical raw material with a wide range of uses. It is mainly used in polyester production and as a solvent for dyes/inks. It has certain toxicity. After combustion, carbon dioxide and water are mainly produced, but incomplete combustion will produce harmful carbon monoxide. According to Beijing Youth Daily, chemical experts said that when producing, transporting and storing ethylene glycol, enterprises generally make safety rules, but if they are not implemented properly, for example, if someone smokes in a factory in violation of safety rules, it may cause a fire. Therefore, it is very important to strictly abide by the safety rules.

It is often further explained that the production process of ethylene glycol is mainly the hydration of ethylene oxide, which is extremely flammable and explosive. In general, the source of raw materials will be cut off after a fire breaks out in the device, but the remaining raw materials in the device are still very dangerous, and improper handling may lead to a secondary explosion, causing heavy casualties to rescuers. There are many similar cases at home and abroad. He said that protective combustion means that the remaining substances can be burned out in a controlled way, and then the next rescue work can be carried out. This is also the usual way for large chemical refining units to deal with fires. It is reported that after the fire broke out, Sinopec Shanghai Petrochemical also launched an environmental emergency plan to continuously monitor the environment of the company's factory boundary and external areas, and the monitoring of volatile organic compounds was normal. Arrangements have been made to strengthen the sampling and monitoring of rainwater outlets, and no impact on the surrounding water environment has been found.
