A chemical plant in Pudong, Shanghai, exploded, killing, killing, and injuring gas or endangering onlookers.

Yesterday afternoon, a fire suppression and rescue team from the fire department of Pudong fought a difficult battle.

Shanghai Yimin Chemical Co. Ltd., located on qingmo Road, Yihua Road, Pudong New Area, exploded, and fire quickly rushed to the site for rescue. Unfortunately, in the explosion caused by illegal operations, a chief engineer was killed on the spot, and two wounded were burned in front and face.

　　Poison gas or endanger onlookers

"The most difficult and important link in the handling of chemical plant accidents is to search for rescue persons and detect whether there is any gas leakage ." Niu chongjun, an instructor of chuansha fire squadron, explained that both rescue procedures require in-depth complex accident scenes, making operations and personal protection very difficult.

"Before the fire truck went out, our rescue operation began ." Niu chongjun introduced that in order to build a fire-fighting army, the fire-fighting department was equipped with a vehicle-mounted "fire-fighting and rescue Command System" in each fire truck of the Chemical Industry Zone ", the system records a large amount of chemical and chemical data. Previously, the fire department collected data on major hazard sources and recorded the data in the on-board database. Firefighters found during the trip that there was a large amount of chloroform at the scene to be disposed of. This substance was mild toxic and could cause damage to the human nervous system and the human heart, liver and kidney. Close field onlookers may be at risk.

When the fire squadron arrived, they immediately set up a warning line with the police and evacuated the onlookers 300 metres away. Meanwhile, the attacking team members put on gray chemical protective clothing and enter the site to search for trapped persons and detect gas toxicity.

　　Explosion caused factory collapse

It is understood that the accident occurred in a reaction kettle workshop in the plant area, while staff from Shanghai Medical Kai Fine Chemical Co., Ltd. borrowed the reaction kettle for specific pilot test work.

The accident occurred in Workshop 1. The workshop is located on the upper and lower floors, with an area of approximately 500 m² square meters. A total of six reactors are set up in the workshop. Each reactor is about 2 meters tall and has an elliptical shape with a diameter of about 1.5 meters. An explosion occurred in one of the reactor.

According to reports, at the time of the incident, the reaction kettle was equipped with 2-chloropyridine nitrogen oxides and other catalysts, and chloroform was used as the solvent to dissolve 2-chloropyridine. In the event of an accident, the top cover of the explosion reaction kettle was blown up. After the top cover hit the floor on the second floor, it also penetrated the ceiling on the second floor, and the wall on the east side of Workshop 1 collapsed in the explosion, the adjacent easy data center on the east side also collapsed.

After the rescue, firefighters immediately use a detector to perform a toxic gas leak check. "You need to be extremely cautious during detection ." Niu chongjun, an instructor of chuansha squadron, said that normally the debris at the scene of an accident explosion is messy and the environment is complex. Accidentally, the protective clothing of firefighters will be damaged.

In the end, firefighters quickly preliminarily measured the gas content with skillful techniques.

　　Toxic substances have not entered the water body

It is reported that the deceased Duan shunqing, 41 years old, is a chief engineer of Shanghai Medical Kai Fine Chemical Co. Ltd. The company said Duan shunqing is indeed a company employee and graduated from a foreign university, but he is not a doctor of the United States. The two wounded were replaced by zhongbing and Luo chengyong, both employees of Shanghai Yimin Chemical Co., Ltd. Currently, two wounded are being treated in the seventh People's Hospital. The doctor said that the injury is mainly concentrated on the hand and face, and the burn area is about 5% square meters. Currently, there is no life risk.

After the accident, the relevant departments investigated. Zhang peijun, director of the Environmental Protection Department of Pudong New Area, said that after a preliminary test, 2-chloropyridine was leaked, and the field was windy and diluted rapidly. On-site staff intuitively determine that there will be no secondary disasters and no further evacuation of surrounding personnel is required. The Department also determined that the toxic substances did not enter the nearby water body, and the specific detection data will be issued overnight on the night of the incident. The relevant environmental monitoring report will also consider the wind direction and wind power on the day of the incident, it can be issued as soon as this morning.
