Laboratory safety is ruthless. Water is generally not obvious in the laboratory, or it will not have a direct consequence soon, and fire is often the top priority of laboratory safety. Fire mainly includes electrical, chemical and combustible fire.

Electrical fire mainly includes short circuit, electric leakage, overvoltage and overload, which is an important task of fire protection and fire analysis. Where in the end caused electrical fire? How to prevent electrical fire? When CSC visited, there was a special technician in the Department. His work throughout the year was to check the electrical, various lines and sockets of the whole building. The sockets bought in similar Liangyuan stores were labeled with a yellow warning label. I don't know if there is anyone in Colleges and universities to inspect electrical safety?

For university laboratories, one is a stove and the other is a cigarette. The stove may be poorly managed, but graduate students work overtime at night, smoke a cigarette, the cigarette end is not extinguished and thrown into the wastebasket, which is the most dangerous. It has been many years since quitting smoking in China, but what about laboratory safety? In some places on the earth, smoking is not allowed in buildings, so as long as it is recess, a group of people are smoking at the door of the building in spring, summer, autumn and winter. They tremble in winter, but they also smoke at the door of the building. Well, one is blocking, the other is combing. Blocking is not allowed to smoke. Combing is specially designed for smoking. For example, a smoking place is designed for each building and floor. It is ventilated, facing the outdoors, and there are ashtrays, such as the smoking place in the airport. Can smoking induce fire be reduced?

If chemicals cause fire, on the basis of strict management, is there a regular chemical scrapping and cleaning system? Drugs have years, and chemicals should also have years. Most of the fires in Colleges and universities for so many years are chemical fires. From the perspective of students, do you know exactly the situation and treatment methods of each flammable, explosive and easily toxic hazard source? For example, what are the dangers of chemicals in an experiment? How to deal with the danger? Whether it is clear here must be specific to the research group and specific experiments. When entering the laboratory in some places on earth, you must have an understanding of your own chemicals, list the chemicals you use, and promise to read the dangerous needs of chemicals, that is, have a more accurate understanding on the basis of general safety knowledge. Of course, from the perspective of teachers, do you have a clear understanding of all the dangers, including the dangers that may be brought to students? Is how to protect in advance.

In fact, the explosion of pressure vessel can also be regarded as a chemical fire. There is a reaction in the vessel and a large amount of gas is produced; Including gas explosion, which is also induced by chemical reaction.

Laboratory hygiene? Sometimes there are more instruments for experiments, so there is no need to care. Just like home, if books and clothes are not so neat, but the inspection laboratory is more tidy than home, this is putting the cart before the horse. Laboratory safety should focus on safety rather than cleanliness. We should find the root of things. Of course, cleanliness is also very important.

The string of safety has been very tight. Once an accident happens, it will be in charge. It will be blocked instead of dredged. In fact, in some places on the earth, the storage of chemicals is relatively loose. The key is the safety awareness of the whole society and the implementation awareness of safety responsibility to everyone.

If everyone is not aware of safety in his own home, he will not be aware of safety in his work. For example, is the safety of socket at home aging? Timely replacement and quality management of various valves. Now I don't know if there are many people lying in bed smoking and burning their clothes? Including if there are firecrackers at home, should they be placed where children can't easily reach?

Why do you want to break the five VIPs? All the five VIPs are quantifiable, work point system, digital and index. Primary school students can rank, and you can understand it at a glance. Then you can talk and boast for most of the day. Those who rank first and boast to heaven, and those who rank 500th are on the list, congratulating everywhere, and even giving awards to blonde resources, Things that can be simply quantified basically have no connotation. They can rush through overtime. Regardless of weekends and holidays, you can rest and I work overtime. You don't get off work and I'm on duty. You can break through in a busy way. Without adjustment and the combination of work and rest, you are prone to make mistakes in your busy work, which is easy to cause other problems. Therefore, we must "break the five only", slow down the pace of scientific research, pay more attention to essential problems and less quantitative indicators, and it is estimated that the safety of the laboratory will be much better. Therefore, we should not only break the five only, but also break all kinds of rankings, do things sincerely and steadily, and strive for development.
