It is still very important to deal with gas explosion accidents. In fact, the detailed introduction, not only to understand the above combustible gas knowledge, but also to understand the measures to prevent gas explosion. The following is my comment on the explosion, I hope you like it. ?

Review the explosion 1

Safety in production is our eternal goal and our unremitting work. Life is only once for everyone, and the most precious things in life are family and feelings ... When all this disappears in an instant, what will the living people leave? The power industry is a high-risk industry. When Electric Power Man goes to work every day, his parents, wife, children and friends are expecting him to come home safely. His responsibility is not only to work, but also to make his family and family happy.

There is a saying in management that details determine success or failure, but I think it is also appropriate to apply it to safety. There are many accidents, but the details are not handled well, which leads to tragedies. Electric workers not only need to have superb electrical knowledge and business skills, but also have the necessary knowledge of safety production, so as to find out what is a violation of safety regulations, understand that illegal command forces them to refuse to operate when they are engaged in risky operations, and prevent accidents.

After reading those twelve tragedies that shouldn't have happened, my mind always echoed with screams, and my heart couldn't be calm for a long time. If time can be repeated, will those who shouldn't have died young understand their mistakes, their lessons, their hard work, their observance of rules and regulations, and their awareness of self-prevention?

In daily work, we must do all the preparatory work, conscientiously implement the on-site investigation system, analyze the dangerous points on the job site in place, improve the work plan and implement the immediate work. You can't start work until you get a work permit from the work permit. The person in charge of the work should explain the work data, division of labor, live parts, dangerous points, safety measures and technical measures to each working group member. Full-time guardians shall conscientiously perform their guardianship tasks and shall not leave their posts without permission or engage in other work at the same time. In case of multi-group work, the person in charge of the work should get the work end report of all team leaders before reporting the work permit in time. Only when the work permit confirms that all the work has been completed can the safety measures on each side be ordered to be removed and power transmission to the line resumed. This series of procedures cannot be relaxed. There must be rules to follow, rules to follow, to ensure safety, and to improve the safety production management system. Strict, meticulous and pragmatic work style is an important guarantee for doing a good job in safety.

The randomness of work plan, the cutting of work tasks and the lack of safety supervision make safety risks out of control. Loose safety management, sloppy work style and random on-site operation are all signs of accidents. Why do we always pay the price of blood for this? Can't we understand some lessons?

The accident has happened and the injured are understanding the treatment of pain. This accident once again sounded the alarm for us, and made us deeply feel its ruthlessness and cruelty from the seriousness of the accident, so his life changed and he didn't know how to go on in the future.

Through the study of the accident, while I feel sorry and sympathetic for him, I am not only thinking about what caused the accident. What lessons should we learn to avoid repeating his mistakes? Judging from this accident and previous accidents, although the accident phenomenon is different, it is closely related to the subjective factors of the parties. To put it bluntly, the "three enemies" are doing something funny. Looking at people's actual work, the phenomenon of "violation of rules, paralysis and irresponsibility" does exist. If the superiors come to check or be stricter, the subordinates will converge, otherwise they will relax their vigilance as soon as the limelight is over. Subjectively, some accidents are caused by the indifference and carelessness of the parties' safety awareness; Objective reasons such as: the person in charge of the work is not responsible, the license of the licensor is arbitrary, the guardianship is not in place, and the analysis of dangerous points is insufficient.

To ensure safety, the first thing is to strictly abide by various rules and regulations, which is the first prerequisite to ensure safety. If we have rules to follow in every job, the probability of accidents will be greatly reduced. For example, in a specific work, it is necessary to carefully analyze the dangerous points, handle the work ticket, take safety measures, hold a pre-shift meeting, and put all systems in place, that is, put the environmental uncertainties and physical factors in place.

Secondly, we should improve our ideological awareness, which is the foundation to ensure safety. In this accident, the parties involved have rich work experience and low technical level (I heard that they are senior technicians), but there are still problems. It is because of his lax thinking that he made such a low-level mistake, and the sewer capsized. Improve ideological awareness, that is, carry out various forms of safety ideological education, firmly establish the idea of "safety first, prevention first", truly implement "three no injuries" in work, change "want me to be safe" into "want me to be safe", let safety be deeply rooted in people's hearts, be vigilant in daily work, pay more attention to observing employees' mental state, and adjust in time when finding unfavorable factors.

In addition, strengthening the study of rules and regulations and business knowledge and vigorously improving business skills are important guarantees for safety. Safety regulations and "two votes and three systems" are the magic weapons to ensure the safe and smooth development of our work. Both managers and our employees should study and master this point seriously. The importance of business knowledge is self-evident. Without it, our work is like a newborn who can't walk, and it is inevitable to hit a wall and fall. In order to make our work more handy and prevent the blind from touching the elephant, we must keep learning to adapt to the rapidly changing knowledge demand.

How much I hate the CEO of Fox after watching this movie represents how unpleasant and disgusting this movie is described. The whole company is a sick little society. As long as a woman stands up and accuses herself of being harassed, she will be considered a traitor and accused. Those stories dictated by women are disgusting. The tragic story will never end. I changed my boss, but it didn't cure me. Change the soup without changing the medicine, hehe

Rogers and Bill are hateful because they use their power to bully and harass women. But I also think the problem lies with those women. They would rather lose their virginity than climb to the top. They thought it was a dream chase, but it wasn't. Finally, it evolved into the right to pursue desire. They gave up moral standards and the opportunity to stand up and fight for rights. They could have chosen to be protected and live honestly, but they didn't want to give up what they had, so they decided to submit to humiliation and indulge these scum.

I really don't understand that Rogers' wife and husband are so promiscuous that they blindly trust him and are willing to fight those weak people with him? ! At the end of the movie, this is very crucial. The company paid 50 million pounds to the victims, but 65 million pounds to Rogers and Bill.

In addition, if those female anchors are afraid to stand up and identify the boss who has sexually harassed for the sake of family husbands and children, they are afraid that journalists and the media will harass their families or children and be hit too hard when watching the news; Maybe they had to endure harassment and stay in such a disgusting industry in order to support their families at first. Then I really don't understand how they explain to their children the money and material life they have gained by putting down their dignity. I think this is the real shame. I shouldn't have chosen that road in the first place … at least I won't. Because such an industry should not, nor is it worthwhile, become their dream, leaving is a suitable choice, just like Keira at the end of the film. Make the right choice, for yourself and for most people.

In the area where natural gas may leak in our plant, natural gas pipelines, regulators, valves, filters, control, regulation, measurement and other components and their connecting components and accessories leak. Between the pressure regulating station and the gas turbine (steam turbine room, gas turbine room and auxiliary engine room in key areas). Gas turbines require higher inlet pressure of natural gas, and the pipeline pressure of high-pressure natural gas pipeline will increase due to the fluctuation of gas source pressure; Trace hydrogen sulfide contained in natural gas is corrosive to pipelines and their accessories, and the pipe wall will be thinned due to corrosion; If the natural gas pipeline is buried underground, it will also produce electrochemical corrosion, which will increase the possibility of pipeline leakage and explosion.

When the gas turbine is started and stopped. If the mixture of fuel and air in the plane reaches the explosive limit concentration, it will form an explosive mixture, which is in danger of explosion. Poor ventilation system of gas turbine in gas chamber, auxiliary engine room and engine room will also form explosive mixture, and fire and explosion accidents may occur when high temperature parts and accessories are encountered in auxiliary engine room. If the liquid components contained in natural gas are not completely separated and removed, they may gather in a lower position and flow intermittently in the form of droplets during the change of fuel flow. Droplets or unvaporized fuel droplets entering the combustion chamber of gas turbine will coke on the fuel nozzle and lead to premature ignition or tempering, and also lead to rapid fluctuation of flame temperature and turbine load. Fuel droplets can burn in the downstream high-temperature gas channel through the combustion chamber, causing overheating and even burning through the high-temperature gas channel components. When a large amount of liquid enters the combustion chamber, it will produce pressure fluctuation and even deflagration.

In order to implement the requirements of the Letter on Doing a Good Job in Warning Education of Chemical and Hazardous Chemicals Accidents issued by the Supervision Department 3 of the State Administration of Work Safety, the Safety Production Department of the Company organized employees to watch the complete works of Warning Education Film on Hazardous Chemicals Production between Life and Death -20 16 and Warning Education Film on Gas Leakage Accidents in Bhopal, pesticide plant, India on the afternoon of July 22, 2065438. It involved "7. 16" in Rizhao, Shandong, "7.28" in Su Jing, Jiangnan, "8. 12" in Tianjin Port, and gas leakage in Bhopal pesticide plant, India. The scene of the accident was shocking, and there were many feelings after the accident.

Explosion review 5

There are different opinions in the industry on whether to cut off the power supply immediately after the gas explosion, because cutting off the power supply in the disaster area may produce an electric spark, which may cause a secondary explosion and expand the scope of disaster damage. However, if the power supply in the disaster area is not cut off, the original power supply system in the disaster area may be destroyed, and the lines may be diverted and damaged, which will bring electric shock danger to the trapped people and rescue workers in the disaster area. According to the previous rescue experience, whether to cut off the power supply in the disaster area should be judged according to the type of gas explosion. If it is a gas outburst explosion, there is still a lot of gas in the roadway. In this case, it is not advisable to cut off the power supply, and rescuers should strengthen their awareness of preventing electric shock. For the cumulative gas explosion, the gas emission speed is not fast and the amount is not large. Generally, the concentration of residual gas after explosion is low, which will not cause secondary explosion. At this time, the power supply can be cut off to improve the safety of rescue work.

After the explosion, it is necessary to establish ventilation conditions as much as possible and restore ventilation in the disaster area as soon as possible. On the one hand, it can eliminate harmful gases produced by gas explosion and improve the living environment of trapped people, on the other hand, it can supplement oxygen to the disaster area and maintain the survival needs of trapped people. However, before establishing ventilation conditions to restore ventilation in the disaster area, we should first judge whether the explosion caused a fire and whether the ventilation was safe according to the changes of toxic and harmful gases such as CO in the return air system in the disaster area. Through the investigation and inspection of the disaster area by ambulance personnel, if it is determined that there is a fire in the disaster area, safety measures should be taken to extinguish the fire first and then ventilate. How to correctly dispatch ventilation system (anti-wind, short circuit, strengthening ventilation, etc.). ), as soon as possible to eliminate toxic and harmful gases in the disaster area and control the expansion of the accident scope, it is necessary to deal with it according to the specific situation of the rescue site. In short, it is necessary to establish a ventilation channel quickly. If the explosion occurs in a roadway containing a lot of gas and harmful gases, which may have a fire source or lose electrical appliances, if the ventilation of the roadway is restored safely and quickly and the victims are found, if the ventilation of the roadway is gradually restored according to the conventional method, there is still the danger of secondary explosion. In order to ensure the safety of rescue, the method of "one-time recovery and remote start" can be adopted, that is, rescuers can wear positive pressure oxygen respirator and then evacuate to a safe area. This method has been applied to the rescue of many gas explosion accidents and achieved good results.
