Alarm Bells Ring! 112 Dead! 2019 Ten Typical Accidents Of Chemical Enterprises

At around 5:10 on March 3rd, a hydrogen sulfide poisoning accident occurred in the phosphate filling area of wududa Chemical Industry Co., Ltd., resulting in 3 deaths and 3 injuries.

The direct cause of the accident is the navigation aids company (wengfuda Chemical Co., Ltd. transport service provider). After transporting the liquid sodium sulfide unloading truck, the transport vehicle still has residual liquid. When the truck escort member uses low-pressure steam to purge and purge the tanning tank in the truck tank, the residual sodium sulfide in the vehicle flows into the trench with the steamed tank sewage, and reacts with the residual phosphoric acid in the trench, producing hydrogen sulfide gas, causing the nearby personnel to breathe in and poison.

At 14:48 on March 21st, there was a particularly serious explosion accident at Tian Jiayi Chemical Co., Ltd. in Yancheng City, Jiangsu province. 78 people died and 76 people were seriously injured. 640 people were hospitalized and the direct economic loss was 1 billion 986 million yuan. In November 15th, the Ministry of emergency management issued an accident investigation report, filed 44 criminal cases and took criminal coercive measures, and seriously questioned 61 public officials suspected of violating discipline and law.

After the accident, the Xiangshui chemical industry park was completely closed, and the chemical industry upgrading plan of Jiangsu province was introduced. The general office of the Jiangsu provincial Party committee issued the "Jiangsu chemical industry safety and environmental protection upgrading plan", and proposed that the province should significantly reduce the number of chemical enterprises along the Yangtze River, cancel the positioning of some chemical industrial parks, and reduce the number of chemical industrial parks.

Then, Shandong, Zhejiang and many other places also introduced the chemical industry upgrading and upgrading plan, and made detailed requirements for the number of chemical enterprises in the region and the norms of the park.

In March 25th, a fire accident occurred in Zhaoyuan Jin Heng Chemical Industry Co., Ltd., located in Xinzhuang Town, Zhaoyuan City, Yantai. 1 people were killed and 4 were injured.

According to preliminary investigation and analysis, the direct cause of the accident is: four. The water in the jacket of the phenyl tin reactor is leaking into the water or raw material four tin chloride, and the water content of the solvent xylene exceeds the standard. The reaction of the metal sodium with the completely reacted metal leads to the production of hydrogen gas, which forms explosive mixed gas with the air.

At 2:34 on April 24th, the leakage of vinyl chloride gas holder in Wulanchabu Dongxing Chemical Co., Ltd., which was located at the Flag Industrial Park of Zhuozi County in the city of Wulanchabu, spread to the carbide cooling workshop. The explosion occurred in the source of fire, resulting in 4 deaths, 3 serious injuries, 33 minor injuries, and a direct economic loss of 41 million 540 thousand yuan.

The direct reason is that the local wind power reached 7 level on the night of the accident. Due to the strong wind force and failure to carry out the overhaul in accordance with the regulations, the operators did not find the gas tank in time, and the compressor reflux was still adjusted according to the conventional operation mode, and the air volume of the gas tank increased, and the speed of the gas tank increased.

5, "5.25" oil tank fire accident in Beilun District of Ningbo

Around 15:10 May 25th, a fuel tank explosion accident occurred in Ningbo Beihai Fuel Chemical Co., Ltd., No. 276, Xinfeng village, Baifeng street, Beilun District, Ningbo, killing 2 people.

The direct reason is that a small amount of light circulating oil is left in the storage tank. The explosive mixing gas space has been formed in the tank and the waste gas recovery pipeline. When Lei Yinbin and Zheng Long are strengthening the waste gas recovery pipeline at the top of the tank, the ignition of the oil tank is caused by the fire welding.

On June 28th, at 18 o'clock, there was an asphyxiation and deflagration accident in Anhui branch of Bengbu Maqi Chemical Industry Co., Ltd. The accident resulted in 2 deaths and 9 injuries.

When the accident occurred, the company violated the workers' limited space operation, resulting in suffocation of the workers and deflagration in the rescue process. Detailed reasons for the accident are under investigation.

At 10:20 on July 13th, the Bayi chemical Limited by Share Ltd of Anhui in Yuhui District of Bengbu City, Anhui Province, had an explosion accident during the production and maintenance operation. The accident resulted in 1 deaths and 1 serious injuries.

According to the preliminary analysis by experts, the cause of the accident may be: there is hydrogen in the raw material tank of No. 3, when the construction personnel are opening the manhole cover plate, the hydrogen is mixed with the air, and it is struck by the iron tool to produce sparks or human body static electricity to cause the detonation. The impact wave leads 1 people to die at the manhole, and 1 people fall down on the lower platform with a height difference of 2 meters.

Around 17:45 on July 19, 2019, explosion occurred in the C air separation unit of Yima gasification plant of Henan gas group, Sanmenxia City, Henan Province, resulting in 15 deaths and 16 serious injuries.

The direct cause of the accident is that the cold box leakage of the air separation unit is not handled in time. There is a "sand explosion". There is a large number of cryogenic liquids in the air cooling box, and there will be a lot of cryogenic liquids in the pearlescent sand of the insulation layer. When the cryogenic liquid evaporates rapidly, the shell of the cold box is cracked and the gas is entrained with the phenomenon of large amount of pearlescent sand, which leads to the collapse of the cold box, resulting in the breakdown of the nearby 500m3 liquid oxygen tank, the rapid release of a large quantity of liquid oxygen, and the explosion and combustion of the combustible materials around the liquid oxygen or oxygen enriched conditions, resulting in a large number of casualties of the surrounding personnel. The specific cause of the accident is under further investigation.

Around 11 p.m. in July 24th, a fire broke out in the two workshop of Tianqi Sheng Ye Chemical Industry Co., Ltd. in Huludao. A total of 2 people were seriously injured and sent to hospital for treatment.

It is understood that Huludao Tianqi Sheng Ye Chemical Co., Ltd. was incorporated in 2010. It is a comprehensive private enterprise that produces fine chemical intermediates. Covers an area of 240000 square meters, has 190 employees, mainly the production of P - chloraniline, P - chloraniline hydrochloride and other products.

At 11:15 on October 15th, at the eastern section of the northern industrial park of Lu Chuan County, Yulin, Guangxi, 3 Guangxi New Material Co., Ltd., a new material Co., Ltd., exploded in a reaction kettle. The accident resulted in 4 deaths and 8 injuries.

According to the survey, around 8:30 a.m., the main raw material of the enterprise was phenol and formaldehyde. When the phenolic resin was produced by chemical reaction, the reactor was exploded at 11:10 a.m., resulting in explosion of the reactor, resulting in casualties and property losses.

It is understood that the site of the explosion is the reactor in the resin synthesis reactor. The reactor is mainly used for the synthesis of phenolic resin from formaldehyde and phenol, and the raw materials and semi finished products in the reactor are about 5 tons.

The ten chemical industry accidents resulted in 112 deaths and 717 injuries. Other accidents that have not been counted have also caused casualties of varying degrees. In 2019, the number of casualties in the chemical industry was nearly 1000.

2019 is bound to be an extraordinary year for the chemical industry. Frequent accidents not only bring devastating economic losses to enterprises, but also stop production and business, and bring irreparable personal injury and psychological shadow to the casualties and their families.

According to statistics, the cause of the accident is very little force majeure, most of which are controllable reasons such as aging equipment, inadequate inspection, improper operation of personnel and so on. In addition, the implementation of key work of some regulatory departments is not in place, safety red line consciousness is not strong, and source access control is not strict, which indirectly promotes the accident. The thought is slack, and it is lucky to think that everyone is so, so there will be no accidents. Every time it is so, there must be no problem, perfunctory, careless, and the importance of accident and safety is not enough. These are all unacceptable.

At the beginning of the end of the year, it is also a time of high occurrence of chemical and dangerous chemicals accidents. Accidents have exposed enterprises' weak sense of safety, and have not seriously absorbed similar problems such as lessons learned, management out of control, serious lack of emergency capabilities and other outstanding problems. This reminds enterprises that safety is not just a slogan, but also in action. It is the responsibility to be responsible for oneself, to be responsible for the enterprise and to be responsible for the society.
