Chemical park safety accidents: 5 status quo, 7 solutions and 4 future trends!

In recent years, the rapid construction of chemical parks in China has gradually become the mainstream of industrial development, and it is also a new model for the development of China's chemical industry. With the continuous expansion of the construction scale and production and storage equipment of chemical parks and the high concentration of chemical enterprises, accidents often occur in chemical parks. In view of the characteristics of centralized hazard sources and large-scale parks, how to make reasonable planning for chemical parks and prevent and control potential serious accidents has become a core issue that governments at all levels, park builders and managers are increasingly concerned about and need to solve. Today, we have an in-depth understanding of the current safety planning of China Chemical parks from the status quo, countermeasures and future trends!

① The regional planning in the park lacks a certain scientific nature, and the layout is chaotic

As far as the current domestic industrial situation is concerned, most chemical parks have not planned a complete set of park security planning Settings, can not be classified according to different security risks in the park, set up security isolation belts, to avoid dangerous explosions, and some enterprises in the establishment of their industrial parks at the beginning of a series of planning, but did not consider the development of enterprises, More and more problems will arise.

From the reality of the situation, most areas have not delimited the chemical industry concentration area or chemical park, hazardous chemicals production, storage activities are still in a disorderly state of development, resulting in the layout of chemical enterprises is not reasonable, some newly built chemical enterprises are facing relocation.

Safety planning has not been listed as a special plan in the overall planning system of the existing chemical park, and regional risk assessment has not been carried out. There are drawbacks of selecting a piece of land for an enterprise, and then carrying out infrastructure construction according to the needs of the enterprise, resulting in insufficient safety protection distance between a number of completed chemical enterprises.

Although some areas have carried out security planning, due to the pressure of investment, the actual park is implemented by the "first come first occupy" entry criteria. For the settled chemical enterprises, the space between major hazard sources is not considered in the initial design, and the possibility of domino effect between major hazard sources is greatly increased.

② The enterprise access mechanism is not perfect

The research on enterprise access mechanism in chemical parks has just started in China, and most chemical parks (especially county level chemical parks) still have the idea of "heavy production, light safety" in varying degrees during the development process, and the introduction of new projects is based on the "basket" introduction principle of "existing, then safe".

In the chemical development zone, there are both large-scale international chemical industry giants, and there are private workhouse-style small chemical plants with less than 10 people. While large chemical enterprises standardize safety management, small chemical enterprises are bound to have low level of safety management, weak awareness of safety laws, dilution of daily safety management in order to pursue immediate interests, and serious insufficiency of normal safety investment, etc. The safety management level at different levels restricts the improvement of the overall safety level of the park.

③ Some parks have not developed complete emergency measures

When the danger really comes, a complete set of emergency measures can usually minimize the economic losses caused by disasters, and at present, most of the emergency systems in most domestic industrial parks are not sound, or emergency facilities have exceeded the service life.

When a fire and explosion occurs, the decision-making system fails or is seriously lacking, it is not possible to communicate with the headquarters in a timely manner, and it is difficult to get first-hand information, so that departments at all levels miss the first rescue time.

(4) The risk of chain explosion accidents is greater

From previous reports, we can find that once an accident occurs in any petrochemical industrial zone, it is often not a single occurrence, and usually a chain reaction will occur and last for a long time.

For example, in the explosion of Lanzhou Petrochemical Company in 2010, the serious fire of more than 300 tanks led to serial explosions in 11 surrounding areas, causing heavy casualties. Such problems are more prominent in cities with rapid economic development along the eastern coast. In the Tianjin big explosion, the sewage in the ruins flowed into the Bohai Basin after the explosion. It has caused serious sea water pollution and economic losses, so the domino consequences should be vigilant for us.

(5) The human and material input mechanism of safety supervision in chemical parks is backward

There are many types of enterprises in the chemical industry park. With the continuous development of the chemical industry, the types of enterprises and the types of services are diversified. It mainly includes storage, transportation, use and production enterprises.

Because the chemical industry itself is unique and dangerous, it is necessary to ensure sufficient manpower and material resources to cope with the safety and production inspections of various chemical enterprises when carrying out safety supervision work. However, most of the chemical park safety supervision departments are not adequately staffed, the professionalism of the supervisors is not strong, the level of business is not high, the supervision work should not only carefully supervise the work of safety production, but also check whether the production standards are consistent with the content, but also review whether the safety permits of various chemical projects are in line with the scope, the task is tedious and complex, therefore, If the input mechanism of human and material resources is not standardized, it is difficult to ensure that the supervision task can be carried out in an orderly manner.

Address the current security situation - 7 measures

① Quantitative analysis of fire risk and qualitative analysis of harm

Before the occurrence of fire and other safety hazards, the staff should take relevant preventive measures immediately. For example, the positioning can be set according to the distribution of various departments in the petroleum and chemical industrial park, and the possibility of different fire hazards in different places can be summarized, the distribution rule and the possibility of occurrence can be realized to achieve a good fire loss assessment.

At the same time, after the fire, do not hastily clean the fire site, should be based on the fire site to carry out a qualitative analysis of the cause of the fire, analysis of the cause of the fire in the end where to determine the type of fire, according to the characteristics of its explosion, the persistence of the fire and the influence on the surrounding areas are classified, so as to gradually establish a perfect fire risk assessment system.

② Establish a comprehensive security model planning

The safety planning of a good petrochemical industrial park should not only include the occurrence of dangerous accidents, but also pay attention to whether the development concept of the enterprise conforms to the concept of green development and sustainable development.

For example, the chemical industry park should not only realize its own economic interests, but also ensure that it can reasonably develop together with the surrounding residential and commercial areas, and cannot destroy the living environment of others. Of course, this should also include the local ecological environment. What humans do to nature is often rewarded in the end. We should coexist hand in hand with nature and make progress together.

③ Improve the safety awareness of all staff and do a good job in safety training

Enterprises should regularly hold safety lectures, actively introduce talents in this area to employees for professional safety training, but also should regularly hold safety drills, do a perfect combination of theory and practice, do not let safety training just stop on the surface, on paper.

Let employees truly understand the dangers of the petrochemical industry, and the various details that need to be paid attention to. Enterprises should also establish corresponding punishment measures, severely punish those employees who neglect their duties, kill the chicken to warn the monkey, and completely change the negative attitude of some employees.

(4) Develop a sound chemical park safety management system

Nowadays, the chemical industry park fundamentally prevents the occurrence of safety accidents, and a perfect safety management system must be developed.

For example, the content of the management system should be posted in a prominent position in the park, clearly indicating that staff should take turns on duty, inspect the placement of drugs, timely store flammable and explosive chemical drugs in a cool place indoors, avoid causing explosions, and encourage staff to fully grasp the rules and regulations, standardize work behavior at all times, and consciously carry out their own work in accordance with the requirements set forth in the management mechanism. Effectively enhance safety awareness.

At the same time, the management department should also be required to implement the safety accountability mechanism, urge all departments to consciously abide by the management system, actively carry out safety management work, take the initiative to organize regular training of employees, so that employees can master safety knowledge, gradually form safety awareness, standardize operation behavior at work, no longer treat their own work casually, and then correct work attitude, carefully classify and preserve chemicals. Eliminating hidden dangers from the source is conducive to achieving the best management effect, reflecting the implementation of a perfect safety management system is of great significance.

⑤ Optimize human resource allocation and mechanism

First of all, according to the scale and workload of the chemical industry park, sufficient safety supervision personnel are equipped to ensure that safety supervision personnel have sufficient professional ability and business level.

Secondly, strengthening the meeting exchanges within the chemical park and implementing the regular meeting system of departments at all levels are conducive to improving the overall work awareness of managers and the efficiency of handling safety work. For example, weekly and daily meetings of the chemical park safety production committee, meetings of leading members of the management committee and seminars of security and technology cadres in various departments are held. Only by fully grasping the existing problems and the situation facing the chemical industry park, can the focus of safety work deployment be highlighted.

Finally, the meeting of supervisors at all levels of the enterprise was held to convey the spirit of the superior authorities through the meeting, put forward various safety production deployment tasks and responsibilities, and plan the safety production tasks in the near future.

Establish emergency rescue centers to improve rescue capabilities

In the process of development, the chemical park should not only pay attention to economic benefits, but also pay attention to safety management and first aid work, so as to increase investment in first aid aid, and actively introduce advanced first aid equipment, equipment, etc., which can provide timely assistance, rapid first aid personnel, and then rescue personnel to avoid the rise in the number of wounded. It shows that it is very important to make full use of advanced facilities for rescue, which can provide rescue efficiency and do a good job in first aid.

At the same time, it should also be combined with various types of safety accidents, formulate a variety of emergency plans, in the face of emergencies, immediately implement the aid program, in order to deal with and solve as soon as possible, effectively improve the rescue capacity.

In addition, chemical parks in different regions can establish shared emergency platforms and rescue centers, so that they can communicate with each other, gradually conclude that rescue vehicles should be equipped, and first aid personnel should be regularly trained to effectively strengthen assistance capabilities.

Therefore, the chemical industry park should attach great importance to enhancing the ability of first aid, integrating emergency resources, playing the role of first aid center, when a prominent accident occurs, immediately send a signal, and quickly send an emergency rescue team to the scene for processing and rescue, in order to reduce losses and reduce the casualty rate.

⑦ Actively use advanced monitoring and management systems

At this stage, in the chemical park safety supervision work, we must keep up with the pace of development of The Times, actively use advanced monitoring and management systems, and install monitoring devices in the entire park, you can observe whether the goods are properly placed in the dead Angle, and there are no standardized operational behaviors in the production of the chemical park production activities at a glance.

At the same time, it is more clear whether many dangerous drugs are stored in the shade, so as to facilitate the supervision personnel to do their own work, and thus reduce the work burden, they can always access the surveillance video, check the work process of staff throughout the chemical park, once found to have random work behavior, it is necessary to give corresponding penalties in accordance with regulations, and play a warning role. Encourage all staff to consciously correct work attitude, seriously complete the work.

In addition, we can also use advanced monitoring and management system to issue safety management workflow, so that the management department will implement safety responsibilities to everyone, so as to enhance the sense of responsibility, more active supervision of the chemical park, and effectively eliminate safety risks.

Future chemical industry - 4 safety trends

① Combination of green development and fire protection

Pollution in the chemical industry has always been the most difficult problem to solve. In the future, people's awareness of environmental protection is getting heavier and heavier, and the requirements for industrial production are naturally getting higher and higher, so in order to meet the new requirements, we should take the initiative to reduce energy consumption, strive to achieve zero emissions, and adopt more clean energy. At the same time, fire protection should be developed towards low energy consumption and high efficiency.

② Focus on the future sustainability of the enterprise

It cannot be denied that any enterprise should pay attention to the sustainability of its future development, which requires relevant industrial parks to do a good job in green energy conservation and environmental protection, and strive to create an ecological system combining nature and industry in the industrial park. Through a series of modern high-tech technologies such as artificial intelligence, big data and other cutting-edge means, the introduction of advanced management experience at home and abroad. To maximize the utilization of resources, maximize the protection of the environment, and maximize the development, and gradually realize the intelligent protection and prevention of disasters in industrial parks.

③ Break through and develop the inherent risk assessment mode

At this stage, the industry is developing rapidly, and various new energy sources and new materials are gradually flooding into the market. If we stick to the traditional risk assessment mode unchanged, it will certainly cause new security risks. Therefore, we should strive to break through the current assessment mode and formulate a new assessment mode according to the characteristics of system integration and the risk relationship of various new materials. And in this mode, we should strive to combine the use of raw materials with recycling, and gradually form a complete evaluation mode.

Use intelligent means to monitor security issues

Digitalization and intelligence have become the focus of the future construction of chemical parks, for the problems in the safety supervision of chemical parks, should be combined with the Internet, the use of advanced supervision technology, intelligent problem discovery and solution, not only can save manpower and material resources, more importantly: through intelligent manufacturing, upgrade the industrial efficiency of the entire chemical industry.
