The main causes of accidents in chemical companies
Thread Content
The main reasons for accidents in chemical companies are: 1. The production process itself is dangerous. Chemical production is in a state of high temperature, high pressure, and continuous reaction. The raw materials used and intermediate products in the production process and final products, such as semi-water gas, shift gas, refined gas, synthesis gas, liquid ammonia, methanol, formaldehyde, acetaldehyde, formic acid, sulfur, methylammonium liquid, sulfuric acid, hydrogen, chlorine, hydrogen chloride, acetylene, vinyl chloride, sodium hydroxide, etc. are flammable, explosive, toxic and harmful, and some are highly corrosive. The complex process flow and high continuity are very unfavorable factors for safe production. Therefore, targeted measures should be taken to achieve safe and stable production. 2. Excessive development and imperfect design In recent decades, chemical companies have developed rapidly, and the growth rate of chemical companies is too fast. As a result, the supply of materials, raw materials, and materials exceeds the demand, and there is enough space to put them into production, leaving hidden dangers. Many enterprises do not fully consider the needs of safe production during expansion and renovation, which increases unsafe factors. 3. Poor enterprise management and no guarantee of safe production. The characteristics of chemical production determine that there must be unified command and close cooperation between workshops and positions, which puts forward higher requirements for enterprise management. However, because the idea of "safety first, prevention first" has not been truly firmly established, there is still the misconception of "emphasis on production, light on safety", and the relationship between safety and production cannot be correctly handled. Safety production cannot be guaranteed. 4. The technical condition of the equipment is poor and in serious disrepair. Chemical enterprises have a lot of equipment and complex pipelines. In addition, equipment safety management is ignored during the production process, causing the equipment to be out of service and aging day by day, posing a major threat to production safety. 5. Poor employee quality and serious violations of rules and disciplines. The key to the safe production of an enterprise lies in whether leaders at all levels of the enterprise consciously abide by rules and disciplines and pay attention to safety. A lot of facts prove: Many leading cadres cannot correctly handle the relationship between safety and production and fail to comply with the requirements of the "Five Simultaneities", resulting in accidents. The poor quality of workers is also one of the main reasons. Main performance: There is a lack of proper chemical knowledge and safety knowledge, serious violations of rules and disciplines, and increased unsafe factors in the production process. 6. Failure to implement the organization. Due to the lack of understanding of production safety by the company's leading cadres, the safety organization has not been implemented, resulting in an increase in the frequency of accidents. Its main performance: a. The security network is not established ； b. The safety agency has not been established or is not functioning properly. ； c. If the safety responsibility system of various departments and various types of personnel is not implemented, you must be careful and be kind: victory:
What's more important is that many of them were illegal operations and illegal commands.
The production process itself is dangerous. When starting the test run, many safety interlocks were set up for safety. After the start of the operation, we generally considered stabilizing production and canceled some interlocks that affected production. The safety factor was reduced, but the efficiency was increased. Managers tend to pay more attention to performance and pay less attention to safety work. For them, it is sometimes empty words that those in charge of production must take care of safety.
The main thing is two points, blind command and misoperation
It's very comprehensive. I think the key is the leadership's attention and the quality of the employees.
The development of an enterprise is based on safe production. Without safety, there is no development. I hope that the leaders of each enterprise can pay attention to this issue.
Safety is no small matter, prevention is the priority. I think most stories can be nipped in the bud and eliminated.* If we do not habitually violate rules and regulations, we must improve employee quality and safety awareness, improve rules and regulations, and implement them conscientiously. I believe many accidents can be avoided.
The poster is very comprehensive and supportive! Just to add: 1. The impact of climate change or unforeseen objective factors: Accidents caused by the sharp drop in temperature around the Spring Festival in southern China and the interruption of power and water supply in some areas cannot be controlled. ； 2. The technology itself is immature and has hidden dangers.
Employees’ self-protection awareness is not strong,
Use people's money to eliminate disasters for others. Use as much as you can, but don't put yourself in trouble.
Be wary of blind instructions and misoperations.
Sometimes designer mistakes are terrible.
In the eyes of many people, accidents are accidental, and they are not that unlucky. The existence of such people is one of the main reasons for accidents.
In fact, the key lies in the leadership's attention and financial strength. If the leadership pays attention and has the financial strength, it can solve the safety audit problem in the design stage and use money to buy intrinsically safe equipment in the equipment bidding. As for future management and operation, it's easy to say.
1. Does the leader pay attention to it? 2. Is the system perfect? How is the company's execution? 3. How is the quality of employees?
Maybe the manager's management focus is misplaced, and the company is regarded as a tool to make money.
Just look at the reported accidents and learn more.: 1. In the trial production stage, the process is immature. 2. Human factors such as operators forgetting to open and close valves, leaving work, leaving work, sleeping on duty, etc. 3. Improper fire prevention and anti-static measures in storage tanks and other material storage locations. Of course, safety is the most important thing.
As for the reality and my feelings: Agree with the original poster’s points 3 and 5. First, the boss values production over safety. They openly call for safety, but they don’t invest in it. Otherwise, during the Olympics, * * Safety was the top priority during the Olympic Games, and some factories were even closed at all costs. However, major accidents such as explosions in chemical plants, fires in warehouses, and coal mine disasters still occurred. Safety investment is the key without direct benefits. Secondly, workers’ safety awareness is weak. Many workers have low educational level and cannot master safety knowledge. Some people rely on their experience and think that they know everything after working for many years. There is always a fluke mentality and it doesn’t matter. * If you are used to it, it is easy to spoil new employees. Others are forced by the system to not report safety hazards to avoid having their bonuses deducted. For example, the famous explosion at the Jilin Chemical Bisphenyl Plant is a clear example. In Jilin Chemical Industry, workers walk in rows of two and in rows of three or more. When cleaning, they even have to remove debris from between the bricks on the road. It can be said that the management should be very strict, but such large accidents still occur. It should not be said. It is said that there are more than 5,000 workers and even more workshop directors who will have their annual bonus deducted due to potential safety hazards. Therefore, the monitor on duty concealed and handled the accident improperly and caused the accident.
I agree with the ideas above, they all make sense. In fact, sometimes a small detail may lead to an accident. I personally feel that: 1. Are there any problems with the design and equipment quality? ； 2. Is there any problem with the process operation? ； 3. Is the management appropriate? ； 4. Employees’ operational level ； 5. Are safety measures in place? ； If there is a problem in that link, an accident may occur.
