Model essay on safety experience of chemical plant

If there is an accident in the chemical plant, it will be a major accident. The following is a model essay on safety experience of chemical plants compiled by me for your reference only. I hope you like it! For more details, please click to view.

Safety experience of chemical plants: There are many flammable and explosive raw materials in chemical plants, and there are many high-temperature and high-pressure reactions in production workshops. In the process of production or storage, the operating procedures must be strictly observed. Once there is any violation of operating procedures, it is easy to have an explosion accident. The safety investigation of explosives in chemical plants is not in place, and the safety awareness of employees is not strong.

How can we prevent chemical fire accidents?

For equipment that has been out of service or does not meet the current regulations. The causes of fire and explosion accidents are diversified, and there are quite a few repeated accidents in some key positions and main equipment. On the one hand, we should strengthen testing and supervision; Warehouse personnel must wear spikes-free shoes or use sparks-free ground; Execute the operation procedure, and automatically cut off or interlock the protection action. Therefore, if the boiler is short of water and explodes, it will exceed the index limit within the scope specified in the regulations. Such as the cut-off valve between the compressor and each section, the safety awareness is not strong, maintenance. With the development of chemical enterprises, firewalls, etc. Technical Specification for Safety Production in Chemical Enterprises is a summary of many years' experience in safety production. At the same time, the maintenance amount is large, mainly to prevent physical overpressure explosion, and the gas holder or acetylene generator is safely sealed with good reliability and gradually replaced with the old one. The occurrence of fire and explosion accidents; Safety accessories and equipment safety.

How to carry out chemical safety work? A series of safety problems caused by a fire accident. Analyze and discuss the causes of fire accidents, convene meetings of various departments, define the development plan of chemical safety work, and implement it. One hour, high scores urgently ask a chemical enterprise about caring for life and safe production.

The topic of my speech is: consolidating the safety foundation of chemical enterprises is the basis for building a long-term safety mechanism for chemical enterprises. First of all, I think everyone is lucky to be here. Why do you say that? Compared with the people lying in the hospital now, we are lucky; Compared with the people in the disaster area, we are lucky; We are luckier than the people in the grave. Safety is the soul of an enterprise and the foundation of its survival and development. If the personal safety of employees is not guaranteed, the enterprise cannot develop and grow; If the personal safety of citizens is not guaranteed, the country will not be prosperous and strong. People appear in society as individuals, and every citizen in society is like a bead. Harmonious and tenacious vitality strings beads together to form an inseparable life. Once the thread loses its vitality, the beads will slide down and there will be no such life. So each of us, whether in society or in the world. Few people can face death calmly, no matter who they are, they always want to enjoy this beautiful world for a long time. It is an inevitable journey of life, but there are no safety accidents.

2 characteristics of chemical production and safety accidents in chemical production

First, the characteristics of chemical production

Chemical production is flammable, explosive, high temperature, high pressure, toxic and harmful. So it is more dangerous than other industrial sectors.

1. There are many kinds of raw materials, semi-finished products and finished products used in chemical production, most of which are inflammable, explosive, toxic and corrosive dangerous chemicals. Special requirements are put forward for the storage and transportation of these raw materials, fuels, intermediate products and finished products in the production process.

2. Chemical production needs harsh technological conditions. Some chemical reactions need high temperature and high pressure, while others need low temperature and high vacuum. For example, in the process of producing ethylene from light diesel oil and then producing polyethylene, the dead angle temperature of light diesel oil in the cracking furnace is 800℃; Dry gas should be separated at low temperature (-96℃), and ethylene gas with purity of 99.99% should be polymerized at 294kpa(3000㎏/cm2) to prepare polyethylene resin.

3. Mass production. In recent years, it is an obvious trend to use large-scale production equipment in chemical production.

4. The mode of production has gradually become highly automated and continuous; The production equipment is changed from open to closed; The control mode is changed from decentralized control to centralized control; The production operation is changed from manual operation to automatic operation of instruments.

At the same time, there are still many intermittent operations in the production of fine chemicals such as dyes, medicines, surfactants, coatings and spices. Because the distance between workers is too close, the post environment is poor and the labor intensity is high, accidents are hard to avoid.

Second, the characteristics of chemical production safety accidents

1, fire, explosion and poisoning accidents have high probability and serious consequences.

Statistics show that the number of deaths from fire and explosion accidents in chemical plants accounts for 13.8% of the total number of dead workers, ranking first; The number of deaths from poisoning and suffocation accidents accounts for 12% of the total number of work deaths, ranking second; Falling from a height and getting an electric shock ranked third and fourth respectively. The explosion of reactors and pressure vessels used in chemical production, as well as the detonation with combustion propagation speed exceeding the speed of sound, will produce extremely destructive shock waves. When the overpressure of shock wave reaches 0.2atm, the brick-wood structure will partially collapse and the wall will crack. If the explosion happens indoors, the pressure will generally increase by seven times, and any solid building can't bear such a big pressure. When the chemical pipeline is broken or the equipment is damaged, a large amount of combustible gas or liquid will be released instantly, which will quickly evaporate to form a vapor cloud, which will be mixed with air to reach the lower explosion limit and dispersed with the wind. It is estimated that the leakage of 50 tons of combustible gas will cause clouds with a diameter of 700 meters, and people covered by it will be burned by explosion fireballs or diffusion flames, and the radiation intensity will reach 14w/㎝2 (the safe radiation intensity that people can bear is only 0.5w/㎝2), and people will also suffocate and die due to lack of oxygen.

According to statistics, carbon monoxide, hydrogen sulfide, nitrogen, nitrogen oxides, ammonia, benzene, carbon dioxide, phosgene, barium chloride, atmosphere, methane, vinyl chloride, phosphorus, phenol, arsenic and other 16 substances caused poisoning suffocation, accounting for 87.9% of the total number of poisoning deaths.

Some liquefied gases heavier than air, such as ammonia and chlorine, diffuse conically at the rupture of equipment or pipeline at 15-30. When the diffusion width is about 100m, people can easily detect it and flee quickly. However, when the influence width of toxic gas reaches 1㎞ or more, when the distance is far away and the concentration of toxic gas is not diluted to a safe value,

There are many factors that cause the accident.

(1) There are many side reactions in chemical production, some of which are not completely clear, some of which occur near the critical point (such as explosion limit), and serious accidents will occur if the process conditions fluctuate slightly.

(2) There are many interference factors affecting various parameters in the chemical production process, and the set process parameters are prone to deviation. In the process of automatic control, there will also be maladjustment or out of control, and manual adjustment is more prone to accidents.

(3) Misoperation often occurs due to poor human quality or ergonomic design.

3, equipment material and processing defects and corrosion and other reasons lead to accidents.

Chemical process equipment generally operates under harsh production conditions, and the effects of corrosive media, vibration, pressure fluctuation and fatigue caused by high and low temperatures on material properties;

Under the action of residual stress in the manufacturing process and tensile stress in the operation process, the material of the equipment will produce cracks in the corrosive environment.

Tattoos grow up. Under certain conditions, such as pressure fluctuation and severe cold weather, brittle fracture will be caused, which will lead to a huge catastrophic accident.

In addition to selecting suitable materials, equipment manufacturing also needs suitable processing methods. If the weld is poor or the heat treatment is improper, the material properties near the welding zone will deteriorate, which will easily lead to cracks and damage the equipment.

4. Accidents are concentrated and frequent.

Many key equipment in chemical plants, especially high-load towers, pressure vessels, reaction vessels, valves that are frequently opened and closed, often have multiple failures or concentrated failures after a certain period of operation, because the equipment has entered the stage of frequent failures in its life cycle. When dealing with frequent accidents, we must take preventive measures, strengthen equipment testing and monitoring measures, and replace expired equipment in time.

We must remember the "explosion and leakage accidents" of chemical enterprises all over the country again and again in recent years. After the explosion, I don't know how many people left this world. The death of the deceased brought us endless sorrow. Only at this moment can we discover how fragile human life is. This is a huge impact on an enterprise and an irreparable disaster for a family.

Judging from the survey results, it is caused by illegal operation and negligence in all aspects, including old equipment, which is not in place at ordinary times. Although people attribute the cause of the accident to this, it is not luck, mental paralysis and "three violations" behind it ... I don't think the accident will necessarily fall on me after a few years or even decades. With this idea, this phenomenon often appears in the production site: someone just took off his helmet; Some people don't wear seat belts when working high above the ground, and some people leave their posts at will ... The embankment of a thousand miles collapsed in the ant nest. Strictness is love, and looseness is harm. After three generations of accidents, the safety chain suddenly broke and flower of life suddenly withered. How to relieve the pain of heartbreaking? Life is precious, and the price of safety is higher. Only by ensuring safety can we produce high-quality products. Only by changing "I want to be safe" to "I want to be safe" can we ensure safety in essence and achieve "one person is safe and the whole family is happy!" Cherish life and put an end to violations! ! Which family doesn't want to laugh, which family doesn't want to be happy, which enterprise doesn't want to be prosperous, and which country doesn't want to be prosperous. If everyone can always remind themselves to start from the details and form a habit and an atmosphere, the security barrier will be strengthened and the happiness of family members will be prolonged. Security is like a colorful silk thread, which connects our beautiful wishes and forms a stable, peaceful and colorful beautiful world. With a sense of security, we can stroll in the fields and rivers in the sunset with a leisurely mood and sing in a low voice, "Picking chrysanthemums under the east fence and seeing Nanshan leisurely"; With the guarantee, we can climb the ladder of life with firm will and sing "One day, I will ride the wind and waves, sail straight up and cross the deep sea"; With the guarantee, our enterprise can be a peach and plum in March; With security, our country can make steady progress on the road of building Socialism with Chinese characteristics. Security is like a radiant sun, illuminating our life, and security is like a long bond connecting our life and death. The sense of security, contained in the affectionate words of lovers, the gentle smiling faces of wives, the yearning of children and the pious prayers of mothers, is a kind of hope, a kind of sustenance, a kind of expectation and the most instinctive and sincere call from life! Safety means the normal operation of machinery and equipment for employees, and it also means the happiness and well-being of thousands of families. Safety work has no end, only a starting point. Listen, the responsibility is more important than the inculcation of Mount Tai, and the voice is still deafening! You see, from the workshop to the department, all employees are working in their posts with a serious and responsible attitude-safety is fire, lighting the lamp of life! Safety is a lamp that illuminates the road of life! Safety is the road, leading life to new glory!

What does safety depend on? Safety depends on responsibility. In daily life and work, every hour and every minute of work, security risks are always like fierce beasts with their mouths open, staring at our fragile bodies and paralyzed nerves. Only by keeping one's position, doing things according to the rules, doing things in a down-to-earth manner, strengthening safety awareness and enhancing responsibility, can the safety of production not be threatened. Only by strengthening the sense of responsibility can we ensure safety and make life better. Safety depends on people. Must have high safety quality, moral cultivation, sense of responsibility, professional skills and healthy body. Safety depends on enterprise leaders, who attach importance to it and are willing to invest to provide a good working environment; Safety depends on system, and the behavior of employees is regulated by scientific system; Safety depends on the mechanism, establish and improve the reward and punishment mechanism, implement the safety responsibility step by step, and implement heavy rewards and heavy penalties; Safety depends on management, establish a safety management system, attach importance to process control and realize standardized management.

Experience of Chemical Plant Safety Mode 4 Safety is an eternal and important topic in chemical plant production, and safety should be put first at all times. "Explosion and leakage accidents" have occurred frequently in chemical enterprises all over the country. The wounded after the explosion don't understand how many people left this world in the accident. The passing of the dead brings us endless sorrow. Only at this moment do we realize how fragile human life is, which is an irreparable disaster for individuals and families.

Leakage and explosion accidents in chemical enterprises are one of the most common public safety accidents in recent years. This proves that chemical industry has become the industrial choice of many cities, but the safety risks of these enterprises have not been paid enough attention by local governments, and there is a lack of sufficient distance and adequate protective measures between them and citizens' daily living areas.

Many people attribute this problem to the rapid development and expansion of cities. Many years ago, chemical plants were located in remote suburbs. Now these places have developed into urban centers or densely populated areas. The relocation of chemical enterprises requires huge economic costs, and its high tax contribution is also unwilling by local governments.

But the problem is that chemical enterprises and residential areas are not a first-come-first-served problem. People have long known the harm of dangerous chemicals in chemical enterprises to human health, and there are also strict safety protection standards, clear EIA procedures and safety supervision measures. As long as these necessary measures and procedures play their due role, or enterprises move, or the planning of residential areas and public places avoids dangerous areas, there will be no intimate relationship between dangerous chemicals and residents.

From the perspective of urban public safety, chemical enterprises and chemical pipelines are obviously the objects that should be strictly restricted and isolated. This is not to limit its legitimate settlement, development and growth, but to fully consider its huge risks. Once its layout and planning are unexpected and destroyed, it may bring great harm to the public and the environment. Although rainstorm, flood peak and operational error are accidental, they should also be avoided. Facing the safety risks of dangerous chemicals, it will pay a heavy price to hope that the accident will not happen.

Only under the scientific, safe and environmental protection planning and layout, relying on the safety supervision system and the safety awareness of enterprises, can we protect the public's life from harm and protect the environment from destruction. Dealing with chemical "time bombs" that threaten residents' lives and environmental safety in time is a realistic topic that both the government and society should deal with.

For chemical dangerous industries, safety has always been the top priority. "Safety first, prevention first" has always been an important principle and eternal theme for chemical enterprises to strengthen safety production management. As the cornerstone of our enterprise, safety is an indispensable wealth leading to a happy life. Since 20xx, Yinglite Company has organized and improved the system, strengthened management and promoted the construction of safety culture. The safety production month in June is in full swing. During the activity, we further realized that the purpose of safety work is to prevent accidents. To do a good job in safe production, we must constantly improve it. Safety work is long-term and multifaceted. Doing a good job is not something that happens overnight. You can't relax all the time, and a moment's negligence may cause irreparable consequences. Many safety accidents occur not because of the lack of system, but because of a weak sense of responsibility and inadequate safety management. Taking the implementation of responsibility as the theme can be said to be to the point. Safety responsibility is focused on implementation, and efforts are made to improve the safety responsibility system to ensure that safety responsibility is transferred to posts and implemented to people. At the same time, efforts should be made to improve the safety awareness and skills of personnel, strengthen the management of outsourcing teams, strengthen organizational performance appraisal, promote the implementation of responsibilities, and deepen the work of safety ideological protection. However, security is far from easy. It needs us and calls us to take action to fulfill our security responsibilities. Execution is an ideology, a responsibility, a will and a culture.

The experience of chemical plant safety passed quickly, and the one-semester study of chemical safety knowledge was coming to an end, which brought me a lot of feelings. It makes me feel that any enterprise is safe and lost in the accident. No matter where we are, we should study safety knowledge seriously.

The success of an enterprise lies in safety, and the failure lies in accidents. Any accident is an irreparable loss to the enterprise, and it also causes irreparable pain to families and individuals. Safety awareness should be firmly rooted in everyone's heart at all times, so that everyone can understand that accidents will happen if the responsibility is not in place, and correctly realize that safety is not a person's problem, but you have me and I have you. It is an interconnected, mutually protective and interlocking chain, and it is a complex and closely connected network. Looking back on the recent traffic accidents in our factory, I remind everyone of the importance of safety again and again. These painful cases reflect the lack of safety education, indicating that there are still great defects in the publicity and popularization of safety knowledge, and our safety management system is still so fragile! "Safety is benefit", this view should be rooted in everyone's heart. First of all, arm yourself, be familiar with the safety system of various operating procedures, and seriously study the relevant laws and regulations on safety; Secondly, develop good habits of safe operation, put an end to habitual violations, and dare to seriously deal with unsafe behaviors around you and even your superiors; Be diligent in inspection, and discover hidden dangers of rectification accidents in time. There are many hidden dangers and dead ends in front-line posts, and habitual violations are more common. If we only talk about safety in form and deal with inspection, then even if we invest more and pay more, the safety environment will not be improved in essence, and the safety management level will never be improved in essence! If every employee supervises each other, reminds each other and checks each other in their daily work, finds loopholes and weak links, prevents unsafe factors, eliminates hidden dangers of accidents, and starts from small things, a safety levee can be built.

No danger means security, and no loss means security. Safety means that in the process of life and production, people's lives are guaranteed, their bodies are not harmed, and their property is not lost.

Let everyone pay attention to safety, always pay attention to safety, keep in mind "safety in production", and strictly abide by the chapter of operating rules and the safety production law! Let everyone clearly understand that breaking the rules means going to an accident, hurting yourself, hurting others, and even dying. Don't have any pity, because maybe a small casual violation will cause great harm or loss and become illegal. If each of us can really realize this, then our work safety will be better, our enterprise will last forever, and we can live happily in a safe and harmonious environment.

No danger means security, and no loss means security. Safety means that in the process of life and production, people's lives are guaranteed, their bodies are not harmed, and their property is not lost. Safety production is the key point of oilfield enterprise management in China, and it is also the fundamental guarantee for our development. Safety is benefit. If I were a security officer, I would plant this idea in everyone's heart (including myself). First of all, arm yourself, be familiar with the safety system of various operating procedures, and seriously study the relevant laws and regulations on safety; Secondly, develop good habits of safe operation, put an end to habits and violations, and dare to be more serious with unsafe behaviors around you and even your superiors; Three, diligent inspection, timely discover the hidden dangers of rectification accidents. Perform the duties of safety officer, make a summary and put forward more reasonable suggestions to superiors; Finally, from wearing a helmet, wearing a seat belt, wearing work clothes and issuing a work ticket, persevere.

Front-line workers are the main force of safety production. Without the participation of workers in supervision and management, it is difficult to do a good job in safety production. When everyone is a safety supervisor, not only do you have to remember the importance of safety production on the day when you are a safety officer, but you should also always pay attention to safety. Even if he is not the safety supervisor, he should keep "safety in production" in mind. If each of us can truly have such a realm, then our work of safety in production will be better. As a safety officer, we should use a sincere heart, safe rules and regulations and thoughtful service to safeguard the safety and health of workers and create a good production environment for people.

Since each of our employees stepped into the door of the chemical industry, they began to understand safety education. "Safety first, prevention first", we keep it in mind. We talk about it all the time, study it every week, and shout it every month. Safety work rules have been broken one after another, and safety learning records are thick one after another. So why is the result of an accident analysis "illegal"? I don't think anyone will have any doubts about the safety work rules, technical operation rules and enterprise discipline regulations. These are the condensation of blood lessons, and everyone is familiar with them. They are three magic weapons for every employee, but why can't they be put into action in the end? The reason is that with the idea of passing the exam and luck, the string of safe production is missing.

I recommend it carefully.
