Technology: Breaking the monopoly global hegemony

Chapter 2147 Biological Laboratory

"At present, the highest level of biological laboratory standard in the world at Bluestar is the Biosafety Level 4 laboratory, also known as the P laboratory in our field.

This type of laboratory is generally graded according to the degree of sealing and the level of danger, among which the safety level and risk factor are the highest.

They are mainly used to conduct experiments that are highly harmful to humans, animals, plants or the environment. Generally speaking, these experiments usually involve highly dangerous pathogens that are transmitted through aerosols or whose transmission routes are unknown, such as anthrax bacteria, Vibrio cholerae, and Ebola virus.

In the early days of Jiuzhou Technology, Mr. Gu, against all odds, invested heavily in building four biological laboratories, P1 to P4, for scientific research.

Can you briefly tell me what are the specific facilities and operating procedures of the P4 laboratory? "

Wang Haiping, director of Jiuzhou Technology's biomedicine department, is evaluating a newly promoted employee.

Li Xiulan was just about to tap the leg of her glasses with her finger, but the moment she raised her right hand, she remembered some special rules that her colleagues had mentioned before.

After being promoted, if superiors ask basic questions about your job, and you rely on smart devices to assist in finding answers too many times, your assessment score will likely be lowered.

Thinking of this situation, Li Xiulan immediately controlled her right hand and searched for relevant information in her mind.

Mr. Gu's photo poster, Kyushu Mecha Group Stage dark horse Xu Xiu won consecutive victories, there will still be drought this spring...

Some information that she usually didn't pay much attention to suddenly flashed in Li Xiulan's mind at this moment, making it impossible for her to recall the answer in an instant.

Wang Haiping saw that the employee had a sad face. Although she felt a little emotional, she still maintained a serious expression.

As a manager in the biomedical department, Wang Haiping is aware that her every move during work is recorded by cameras and other invisible equipment.

If he chose to show mercy to the newly promoted employee in front of him, then [Xiezhi] would definitely keep a strict record of his actions and would also give this employee some bad labels and scores.

Even at this moment, Wang Haiping was already counting down in her mind. If the employee still couldn't answer after the countdown, she would have to write a poor comment.

Although the other party may have a chance to be promoted in the future, that may be a story many years later.

Although there was no clock at the scene, Li Xiulan seemed to be able to hear the ticking sound of a clock nearby.

Phew… “Please give me a few seconds to recall.”

Taking a deep breath, after a brief calm, Li Xiulan tried to recall the recordings of the camera, other detectors and SR2 glasses. After a moment, she replied: "If I remember correctly, there are many specific facilities in the biosafety level laboratory. For example, the core area of ​​the biosafety level laboratory is equipped with an automatic interlocking device, which can ensure that any adjacent doors will not be opened at the same time, ensuring that the materials, viruses, and experimental subjects of the biological laboratory will not be leaked to the outside world.

The P4-level laboratory is equipped with biological safety cabinets produced to the highest standards, ultra-low temperature refrigerators that can isolate air, centrifuges, electric cell culture cabinets, microscopes, laboratory tables and other equipment.

All major operations are required to be carried out in a biosafety cabinet, and the biosafety cabinet equipment must maintain a negative pressure state during operation and be directly connected to the roof to ensure safety during the experiment.

These devices not only require high-standard production, but also must be equipped with daily inspection staff, daily punctual inspections and irregular spot checks. If the equipment is not used under high load, it must be maintained strictly in accordance with the equipment maintenance cycle set by the software system. "

After answering the questions she remembered, Li Xiulan saw that the supervisor in front of her was still smiling, as if listening to her answer. She immediately made up a story: "I took special courses before applying for the promotion assessment. In class, our teacher said that P4-level laboratories are generally equipped with high-efficiency air filters around them, and there are at least 10 doors from the laboratory gate to the core area of ​​the laboratory. Seven of the doors are interlocked. In other words, if the previous door is not closed during entry, the next door will definitely not be opened. This can avoid microbial and bacterial contamination caused by air circulation to a greater extent.

In addition to the complicated design of the door lock, the design of the changing area is also very complicated. In addition to the outer changing room, shower room and inner changing room, our Jiuzhou Technology's P4 laboratory also has a special toilet for personal hygiene and cleaning, but I don’t know what the difference is in the design.

For special materials, personal belongings and some equipment that cannot be brought in and out of the main laboratory from the locker room, it is necessary to use the high pressure sterilizer, immersion sterilization tank, fumigation room or ventilation transfer window with sterilization device on the wall of the main laboratory for transfer or sterilization.

The disinfection area is not designed as a normal spray disinfection area, but a chemical shower room. Laboratory staff are required to first use a chemical shower to disinfect the surface of their positive pressure protective clothing when leaving the main laboratory..."

Just like answering a question that "will get points if it makes sense", Li Xiulan racked her brains to recite all the relevant information about the P4 laboratory in her mind.

6◇9◇Book◇Bar

In order to satisfy the supervisor, she even gave some spoken answers and provided feedback on the use of equipment based on her previous work experience and insights gained from working in a lower-level laboratory.

“Of course, I personally feel that these cumbersome and complicated designs will take some time for every researcher entering the laboratory, but a P4-level biological laboratory is like a cage that holds the world’s most terrifying demon. To enter and exit here, no matter how cumbersome and cautious one is, it is not too much.

director……"

After hearing this answer, Wang Haiping nodded slightly.

"Well, you have learned the basic knowledge very well, but it seems that you don't have a flexible grasp of it. You have just entered our laboratory to work. Remember to keep a stable mentality in our laboratory. The more emergency situations you encounter, the calmer you must be.

When Mr. Gu was learning how to build a biological laboratory with us, he told us that as biological laboratory staff, we enjoy high benefits and high salaries, but we also have higher and heavier responsibilities. "
