Identification of operational responsibilities

A 6D375B-4A labyrinth compressor, 9860M3/H, inlet pressure 0.025MPA, outlet 3.5MPA, the operating method stipulates that the inlet pressure must not be negative (a relatively general sentence, there is no detailed explanation of how to do it). In actual production, due to fluctuations in the air source, the compressor inlet pressure may become over-negative in a short period of time. This is generally monitored closely and does not require processing by the compressor station. The pressure will be restored after a while. One day, negative pressure appeared at the compressor outlet again. The main operator was out for trouble. The assistant operator got excited and pressed the emergency stop, which caused a series of chain reactions and caused the entire system to shut down... Please help analyze, what would you do in a similar situation, was the operator wrong again, and how to characterize this accident...

Such a situation should really not happen. First of all, I think it is certain that the deputy operator has a certain responsibility for improper handling of emergencies. This may also be caused by being too careless, unskilled or inexperienced.; Second, the technicians who wrote the operating procedures are also responsible. The operating procedures may not be very detailed on how to deal with negative pressure after it is caused. They should state how to ensure the slight positive pressure at the inlet. ; Third, it is not right for the main operator to leave his post at work. No matter what happens, he needs to stick to his post. At the very least, he must have someone to replace him. If it were me, I would like to change the operating method on the one hand, and secondly, summarize or make a card out of my own and others' daily operating experience, and store it in a fixed location in the operating room. For emergency use. I think this accident was a man-made accident. First of all, it was definitely caused by improper operation. As for the detailed division of responsibilities, it depends on your company's rules and regulations. The above is my personal opinion, please forgive me for any inappropriateness.

This is a standard human operation accident! The main responsible person is the deputy operator, the chief operator is jointly and severally responsible, and the workshop is also responsible. There are omissions in management, daily training is not in place, the professional quality of the personnel is not high, and there is no correct, reasonable and scientific judgment on emergency abnormal situations. The operating regulations are rigid and of course not very detailed. Operation precautions, but operators must also have certain operating experience. Modern factory operations are basically controlled by computer DCS. Personnel must make their own reasonable judgments on abnormal situations. Personnel with inexperience or who are too sensitive should not be employed.

The main responsibility cannot be placed on the deputy operator. The operator's task is to follow the procedures. Only if he violates the operating procedures can he be punished. The biggest problem for operators is whether they have the ability to handle abnormal events. Without this ability, those who act impulsively must be punished. However, "the operating law stipulates that the inlet pressure must not be negative. The compressor inlet pressure has become negative in a short period of time." It is obvious that the management and procedures are incomplete.

I know about this, it seems that the assistant operator was fined some money, the main operator said that he went to WC, and the squad leader was also fined... Safety first, this is equivalent to over-defense, and nothing was done in the end: lol

I think this kind of accident is mainly a problem of the operators, followed by a management problem.

If the tiger comes out of the coffin and the beautiful jade is destroyed in the coffin, whose fault is it? ? ? It doesn't matter who is responsible, no one is at fault, even if there is a shutdown accident. The fundamental question is why negative pressure occurs. Since we all know that negative pressure operations cannot occur, why not solve this negative pressure problem? ? ? What’s the point of pursuing whose responsibility it is now? ? ? We still need to fundamentally solve this problem, otherwise once a new person comes to operate it in the future, such errors may still occur.

After reading it, I think it should be the treatment method on the 6th floor. It should have been a procedural error, and the operator was responsible for it during production. The handler was fully aware of it, and those who were dealt with it deserved it. Who is the operator who is directly harmed?

Someone must bear the responsibility. The key is to learn lessons. I won't do this next time. When you encounter a problem, you must first learn to report it. If you are not sure, please do not operate for the time being.

As an operator, you often use money to learn knowledge. As an operator, you should learn more * , improve yourself. As the main and auxiliary operators, they should communicate with each other, and the auxiliary operators should also pay more attention to the production situation.

Safety comes first, and it is understandable that we are overly defensive... The operator was a little unjust in this matter.
Reply #122008-01-09
The assistant operator's inexperience is the main reason for the accident! Since it has happened before, the assistant operator should know how to handle it properly! Otherwise, the assistant operator is usually too irresponsible and will not deal with the problems that arise! Others are indirectly responsible! Because the operation method must not be copied mechanically!

It is obvious that the vice-presence has been passed on by others. 1. Now, whenever an accident occurs, it is classified as a violation. 2. What cannot be classified as a violation is poor management and insufficient supervision by safety managers. Therefore, it is always the operators and safety management personnel who are most severely assessed. Analysis from this accident: 1. Because the operating method states that negative pressure is not allowed, the personnel who prepare the operating method are primarily responsible. 2. The main operator cannot be on guard all the time and must go to the toilet. Therefore, I wonder how much power the assistant operator has. I wonder if your factory has any regulations, such as how to handle abnormal situations. 3. The operation method of countermeasures for the occurrence of negative pressure is obviously not clear. 4. In the past, negative pressure would be cured after a while, but the reason why the negative pressure occurred was not found out. The technical personnel bear the management responsibility. Therefore, from the perspective of this accident, the personnel who compiled the operating procedures were primarily responsible, and the technical management personnel were secondary responsible. If you have received training on negative pressure treatment, or it is clear that the assistant operator is not allowed to perform this operation, the assistant operator will bear indirect responsibility. The main operator should have basically no responsibility. Therefore, only by handling accidents according to the degree of negligence can we truly enhance the safety awareness of all employees and implement the safety production responsibility system, but it is difficult to go beyond that. Safety has a long way to go.

Your factory handled it incorrectly. The operators were not wrong in following the procedures. The operating laws have legal effect. Problems: 1. It did not attract the attention of domestic personnel. 2. Any unreasonable operating methods were strictly revised in a timely manner. 3. If the system requires no air, it is very dangerous to pump negative pressure. The main responsibilities are the author, approver and manager of operating procedures.

1. First of all, there are problems in the design. Generally, the compressor inlet should have an inlet pressure chain alarm and a trend record with paperless records. 2. There is a process for the input pressure to decrease, and the operator must inspect it in place. The gas cabinet has been deflated in the past, so we should pay close attention to it. The operator is responsible. 3. The responsibilities of the main and deputy operators should be clear. A qualified manager is a qualified trainer, and the workshop has management responsibilities. Not long ago, a similar situation occurred with one of our 6M32 compressors.
