Personal reflections on chemical explosion accidents_Feelings on chemical explosion accidents

If a chemical plant explodes, it can release a large amount of energy, generate high temperatures, and release a large amount of gas in a very short period of time, causing high pressure in the surrounding medium and causing great damage to people's property and safety. The consequences are disastrous. So how to write personal thoughts or feelings about chemical explosion accidents? The following are the reflections of chemical explosion accidents, welcome to read.

Reflections on chemical explosion accidents

In recent times, safety accidents have occurred frequently in transportation, production, food hygiene and other fields. No, the "7.16" explosion in Dalian has not left the lingering news. Another chemical plant explosion occurred in Xintai City, Shandong Province.

The frequent occurrence of many accidents such as the "7.16" explosion accident in Dalian and the "11.19" Xintai Chemical Plant explosion accident all impact people's survival and development. Therefore, safety accidents have brought serious consequences to us. Confusion and thinking.

The cause of the accident shows that our employees violated many regulations during the production safety process, but the consequences are serious and irreparable. The prerequisite for safe production is compliance with regulations and laws. Effectively achieving safe production and improving safety awareness start from every day's work, starting bit by bit. Employees are on the front line of production, and the on-site environment is complex and sometimes contains uncertain factors. This requires us to keep a cool head at all times and constantly improve our business skills when working and dealing with problems to cope with changes and guard against various emergencies.

Every employee must have a sense of crisis. Accidents are punishment for those with paralyzed minds. Don't let a moment's negligence become your lifelong regret.

After watching this time, I also realized that team safety management is an important guarantee for achieving safe production. As the executors of various systems in the enterprise, we must do a good job in safety management of the team in a practical and conscientious manner. Each of us should pay more attention to and keep abreast of various problems and problems that exist in production at any time. unsafe factors, etc. When potential safety hazards are discovered, corresponding measures must be taken promptly to resolve them to avoid accidents. Only in this way will each of us be more energetic and long-term security guaranteed.

Thoughts on chemical explosion accidents

The explosion accident in the Improve work and truly implement various measures to strengthen production safety. Natural gas explosion is a combustion process that produces high temperature (up to 3000°C) and high pressure in an instant (thousandths of a second). The explosion wave speed can reach 300m/s, causing great destructive power. If natural gas leaks encounter high-temperature equipment, open flames, static electricity, lightning or improper operation in the power plant, explosions and fires will occur. In the confined space, people will suffer from hypoxia, suffocation, and even death, which will bring serious consequences to the safe production of the unit and people's lives and property. An immeasurable loss.

The areas where natural gas may leak in our plant are from the natural gas transmission pipelines, pressure regulators, valves, filters, control, regulation, measurement and other parts and connections between the pressure regulating station and the gas turbine. , accessories, etc. (turbine room, gas room, auxiliary engine room of gas turbines in key areas). Gas turbines require high natural gas inlet pressure, and high-pressure natural gas pipelines will increase pipeline pressure due to fluctuations in gas source pressure; trace amounts of hydrogen sulfide contained in natural gas will corrode pipelines and their accessories, and the pipe walls will become thinner due to corrosion; If natural gas pipelines are laid underground, electrochemical corrosion will also occur, which will increase the possibility of pipeline leakage and explosion.

Gas turbine during startup and shutdown. If the fuel and air in the machine are mixed to reach the explosion limit concentration to form an explosive mixture, there is a risk of explosion. Gas turbines with poor ventilation systems in the gas compartment, auxiliary engine room, and turbine room can also form explosive mixtures. Fire and explosion accidents may occur when high-temperature parts and accessories in the auxiliary engine room are encountered. If the liquid components contained in natural gas are not completely separated and removed, they may accumulate in a lower position and flow intermittently in the form of droplets when the fuel flow rate changes. Liquid droplets or unevaporated fuel droplets entering the gas turbine combustor can coke on the fuel nozzle and cause premature ignition or flashback. They can also cause rapid fluctuations in flame temperature and turbine load. The fuel droplets can burn in the downstream high-temperature gas channel through the combustion chamber, causing over-temperature or even burning through the high-temperature gas channel components.

When a large amount of liquid enters the combustion chamber, pressure fluctuations and even deflagration may occur.

Preventive measures:

1. Establish a sound safety management system.

2. Strengthen employee education and training, improve employee safety prevention and emergency response capabilities, and strictly enforce safe operations. Before ignition of the gas turbine (especially when ignition fails or is re-ignited after automatic flameout), the gas turbine must be purged in accordance with the operating procedures.

3. Improve work responsibility, conduct frequent inspections, and discover equipment defects in a timely manner; use scientific means and existing testing instruments to promptly discover hidden leaks and take preventive measures in advance. When a serious natural gas leak occurs, the following phenomena will occur: 3.1 The working pressure of natural gas changes. 3.2 A strong air flow sound can be heard near the leak source.

3.3 The handheld alarm device will sound an alarm. 3.4 When the leakage is large (high concentration), the fixed alarm will issue an automatic alarm.

4. Strengthen fire safety management. Anyone entering a natural gas area is strictly prohibited from bringing fire.

5. Take anti-static and explosion-proof measures. Employees are strictly required to wear labor protection. Anyone entering the natural gas area is required to wear anti-static overalls, and mobile phones are strictly prohibited. The static electricity and lightning protection grounding devices of natural gas pipelines and the grounding protection wires of electrical equipment are tested every year to ensure that fire and explosion-proof safety devices are intact. , so that static electricity and lightning can be released in a timely manner; use explosion-proof lighting, explosion-proof instruments and other explosion-proof electrical equipment

6. Ensure that the fire protection system is intact.

7. Carry out nitrogen replacement according to regulations to ensure construction safety.

Reflections on the Chemical Explosion Accident Sample

At around 19:00, a deafening explosion ripped through the sky over Yushe County, Shanxi Province. An explosion occurred suddenly in the polymerization workshop of Shanxi Yushe Chemical Co., Ltd. less than 500 meters away from Xiangyang Village in Beicheng Town, Jicheng City. Li Zhiming, 56-year-old deputy secretary of the Beixiangyang Village Committee in Jicheng Town, Yushe County, Shanxi Province, recalled that moment and said it could be described as "frightening".

On the morning of the 21st, according to official news, as of 9 o'clock, the accident *** resulted in the deaths of 4 workers on duty and in nearby sections, 2 serious injuries, and 3 minor injuries. The injured have been properly placed. Various hospitals in the county provide treatment. Reporters saw at the accident site that rescue personnel such as safety supervisors, public security, health, and fire fighters were still busy, and the pungent smell inherent in chemical plants permeated the air.

When the accident happened, Li Zhiming was standing in the yard of his home. “First he saw a ball of fire in the sky above his head, and then there was a loud bang, and all the window glass in the house was shaken in an instant. It was broken, and only after the people in the village reacted did they think of holding their heads and running for their lives.

Li Zhiming said that the first reaction of the village committee cadres after the accident was to evacuate nearly 600 villagers in Beixiangyang Village to prevent a second incident.

When China News Service reporters arrived in the village for interviews, more than 180 rural courtyards were still shrouded in the darkness before dawn in winter. In the darkness, there were only protective guards composed of more than 30 villagers. The village team warmed themselves in front of the burning straw outside the village committee office compound.

Several rooms in the village committee were in a mess, and the window glass was shattered, and some of them were originally closed. The door panels of the house were lying on the ground, the wall coverings were peeling off, and there was a thick layer of dust on the ground, sofas, tables and some electrical appliances.

Several villagers told reporters that almost everyone in the village was covered with dust. The window glass was shattered at the same time. Villagers said that the explosion did not cause serious injuries to the villagers. Only a few people had their skin scratched by the glass, but the explosion made their houses temporarily uninhabitable, and the walls of several households had cracked. A deep gap

Wang Hongchang, the Propaganda Minister of Yushe County, said that after the accident, leaders and experts from the relevant departments of the Shanxi Shengjinzhong Municipal Government rushed to the scene to organize rescue operations and deal with the aftermath. After inspection by the Shanxi Provincial Environmental Protection Department, the accident was confirmed. The air monitoring above the place where the accident occurred did not exceed the standard, and there was no discharge of sewage from the factory area, which basically had no impact on the environment.

At present, the aftermath has been fully launched and the cause of the explosion is under investigation.

Shanxi Yushe Chemical Co., Ltd., formerly Shanxi Yushe County Chemical General Plant, was founded in 1974. It is a comprehensive medium-sized chemical enterprise that mainly produces more than ten kinds of chemical products and has a fixed It has assets of RMB 150 million, 1,500 employees, annual output value of RMB 160 million, and annual profits and taxes of RMB 20 million. New safety management concepts: Some new safety management concepts were introduced in the speech competition, and the concepts of safety philosophy were elaborated from a historical perspective; systematic safety; essential safety; safety system theory; cybernetic principles; information theory principles; behavioral science Principles; incentive theory; accident system elements; factors affecting people's safety behavior; analysis of people's safety qualities; accident psychology; accident loss analysis; modern safety management technology; scientific means of safety management; safety evaluation, etc. These new safety management concepts give people a refreshing feeling. As a safety officer, I must quickly improve my safety skills and flexibly apply these new management technologies and methods in actual work. Adhere to people-oriented, strengthen management, improve essential safety as much as possible, improve the safety awareness of all employees, regulate people's unsafe behaviors, eliminate various habitual violations, eliminate safety hazards, and do their best to provide employees with a good civilization , a safe production environment. Do a good job in ensuring the safety of the unit's production.

Summary of thoughts on chemical explosion accidents

Accidents occurred frequently in my country's chemical industry in 2014. In July alone, four sudden accidents occurred in chemical and petrochemical enterprises, which had a great impact on people's lives and the surrounding environment. It has had an immeasurable impact.

On July 13, a copper acid water leakage accident occurred at the Zijinshan Copper Mine Wet Processing Plant of Zijin Mining in Fujian, causing serious pollution in some waters of the Tingjiang River. On July 16, an oil pipeline exploded in Dalian, causing a crude oil leak. On the morning of July 28, the demolition of Nanjing Plastics Factory No. 4 caused a leak of propylene and caused an explosion. That night, more than 7,000 chemical raw material barrels from two chemical companies in Yongji County, Jilin Province were washed into the Songhua River by floods. This series of events may seem accidental, but in fact, if we delve deeper, we will find that these are the inevitable results of some shortcomings in my country's current chemical industry. The Songhua River basin among them has been polluted more than once, and the most serious one even attracted close attention from Russia. What impact have these frequent chemical accidents had on the surrounding environment? Taking the Songhua River, which has been repeatedly polluted, as an example, let's briefly analyze the impact of chemical accidents on the surrounding environment.

First of all, the pollution of the Songhua River waters has an immeasurable impact on the surrounding ecological environment. The Songhua River pollution incident involved a large number of pollutants. Thousands of chemical barrels were washed into the Songhua River and spread rapidly in the river, resulting in widespread contaminated waters. The ecological environment in the water has been destroyed, and a large number of aquatic animals and plants have been polluted, causing the ecological environment of the Songhua River and surrounding watersheds to be on the verge of collapse.

Secondly, the pollution of the Songhua River waters affects human life. Residents' domestic water in the surrounding basins has been polluted, causing water shortages in several cities in Jilin. Pollutants in the river will gradually accumulate, making fish, shrimp and other creatures no longer edible. It is unknown whether the pollution and damage caused by chemical accidents to water quality will not be eliminated for a long time. Do you still remember the famous pollution-induced diseases in Japan? Minamata disease and Itai-itai disease? I believe everyone has a deep memory of the scenes when people who were persecuted by environmental pollution fell ill. I think those scenes can be described as "shocking". To describe, if similar strange diseases appear in our country in a few decades, who should those who have been harmed turn to to seek justice for them? And what can we do? Obviously, for the accidents that have already occurred, we The only thing we can do is to take action to eliminate pollution as quickly, efficiently, and without leaving any consequences. After solving the current visible pollution, it is more important for us to reflect and think about the causes of the accident, and what can we do? Can these risks be avoided in advance and the possibility of accidents reduced?

Thirdly, water pollution accidents will have an impact on a series of local industries, thereby causing resistance to economic development. Water is one of the indispensable raw materials for any industry. The Songhua River is also an important local water source. If the river water is polluted, the water use of most industries will be affected to varying degrees. Obtaining water sources from other channels will inevitably increase production costs. This will in turn have an impact on local economic development.

Although the pollution accident in July seemed accidental, as thousands of raw material barrels were washed into the river by sudden floods, has anyone ever thought about why such a large chemical plant was built so far away? A place close to an important water source? Doesn’t this violate the most basic principle of site selection for chemical plants? If you think about it more deeply, the Songhua River is an important water source for residents in Northeast China and one of the rivers in Russia. Why is it such an important waterway? Chemical accidents occur frequently, and the surrounding chemical companies that violate regulations are repeatedly banned? I believe that the reasons for this problem involve many aspects: imperfect laws and regulations, insufficient efforts to control violations, weak self-protection awareness of surrounding residents, and inadequate supervision?

China is in the process of rapid development in all aspects, and the speed of industrialization is growing rapidly. The chemical industry is the main force of economic growth, and a large number of new chemical plants are being established. Green chemistry, atom economy, environmental friendliness and sustainable development have become the current development trends of the international chemical industry. As a student majoring in chemical engineering and technology, we must always remind ourselves of the relationship between chemical safety and environmental protection. If we participate in the site selection and design of chemical plants in the future, we must always keep our environmental and humanistic principles in mind. , don’t be dazzled by benefits and seek benefits regardless of the environment.

Thoughts on chemical explosion accidents

At around 14:48 pm on March 21, an explosion occurred at Jiangsu Tianjiayi Chemical Co., Ltd. in Chenjiagang Town, Xiangshui County, Yancheng City, Jiangsu Province. Explosion accident. Jiangsu Tianjiayi Chemical Co., Ltd., where the accident occurred, was established in April 2007. It covers an area of ??about 220 acres and currently has 195 employees, including 45 engineering and technical personnel. It mainly produces chemical raw materials and chemical products, and its business scope includes m-hydroxybenzoic acid, anisole, etc. The explosion killed 78 people and some people were slightly injured.

While deeply saddened, I hope that this tragedy will serve as a warning to all companies. When learning lessons from the accident, don’t just stop at “slogans”! This is one of the most serious safety accidents in my country’s chemical industry in recent years. Not the biggest, but the most tragic. Therefore, we hope that our companies can immediately tighten the heartstrings of safe production, conduct self-correction and self-examination, and nip problems in the bud. Don’t let safety production become just a formality and slogan. Don’t use all kinds of dazzling safety production slogans in the factory area in advance, such as “eliminate hidden dangers, safe production, safety is life, quality must be guaranteed, eyes cannot tolerate a grain of sand, safety”. Don't be careless, safety first, prevention first, standard operation, safety comes from vigilance, accidents are caused by paralysis, safety is no small matter, responsibility is heavy, abide by the rules and laws, care for life, guard against the slightest, keep the alarm sounding, be people-oriented, and pay attention. Safety, safety first, production second” and so on. Banners, in various versions, with various earnest words, are hung in the most eye-catching position in the factory. However, if these slogans are truly regarded as ironclad rules and can truly be instilled in production, there is a question mark. It can be said that the majority of people are just relying on formalities and slogans and taking chances.

In recent years, the country's environmental protection and safety inspection supervision has become stricter. Companies call it a storm, and everyone is in danger. They make irresponsible remarks about environmental protection and safety inspection supervision. But when an accident actually occurs, who can take responsibility? What?

Especially for high-risk companies, any tiny hidden danger can destroy employees and the company. When a safety incident occurs, no one can guarantee your safety. You can only keep it safe in normal management. We must pay close attention to every detail, so that the person in charge, managers, and employees of the enterprise can truly realize that safety production is the first important factor. Otherwise, there will only be endless sorrow.

Enterprise safety management should always be ranked first. If safety cannot be guaranteed, there will be no development! Safety production cannot be left to chance. Increase the education and training of employees on safety production to achieve in-depth People's hearts. Do a good job in safety production management and do not slack off. If there are safety hazards, make timely rectifications from top to bottom to check for leaks and fill in the gaps. At the same time, we will increase investment in safety facilities, comply with various safety production systems, and implement effective safety management. From the staff to the production process, we must not take it lightly. We must put safety first to ensure that there will be no safety accidents.
