Chapter 2147 Biological Laboratory
"At present, the highest level of biological laboratory standard in our Bluestar is the biosafety level 4 laboratory, also known as the P4 laboratory in our field.
This kind of laboratory is generally graded according to the degree of sealing and the level of danger, among which the safety level and the risk factor are the highest.
They are mainly used for experiments that are highly harmful to humans, animals, plants or the environment, and generally, these experiments usually involve high-risk pathogens that are transmitted through aerosols or unknown transmission routes, such as anthrax bacteria, Vibrio cholerae, and Ebola virus.
In the early days of our Jiuzhou Technology, General Manager Gu went against all odds and invested in the construction of four biological laboratories from 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, the director of the biomedical department of Jiuzhou Technology, is evaluating an employee who has just been promoted.
Li Xiulan was about to point her glasses with her fingers, but the moment she raised her right hand, she remembered some special regulations that her colleagues had mentioned before.
After being promoted, if the superior asks basic questions about the job, and the person being asked relies on smart devices to assist in finding the answers too many times, the assessment score is likely to be lowered.
Thinking of this, Li Xiulan immediately controlled her right hand and searched for relevant information in her mind.
General Gu's photo poster, Kyushu Mecha Group Match dark horse Xu Xiu's consecutive wins, there will still be drought this spring...
Some information that she usually doesn'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 the employee's sad face, and although she felt a little emotional, she still maintained a serious expression.
As a manager of the biomedical department, Wang Haiping knew that every move she made during her work was recorded by cameras and other invisible equipment.
If she chose to be merciful to the newly promoted employee in front of her, then [Xiezhi] would definitely strictly record her actions, and at the same time give this employee some bad labels and scores.
Even at this moment, Wang Haiping was counting down in her mind. If the employee still couldn't answer after the countdown, she could only write a poor comment.
Although the other party might have a chance to be promoted in the future, that might be a story many years later.
Although there was no clock on the scene, Li Xiulan seemed to be able to hear the ticking sound of the clock coming from her ear.
Huh...
"Please give me a few seconds to recall."
Take a deep breath, and after a brief calm, Li Xiulan tried to recall under the record of the camera and other detectors and SR2 glasses. After a moment, she replied: "If I remember correctly, there are many specific facilities in the biosafety level 4 laboratory. For example, the core area of the biosafety level 4 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.
Inside the P4-level laboratory, it is also equipped with biosafety cabinets produced to the highest standards, ultra-low temperature refrigerators that can isolate air, centrifuges, and electric cell culture Cabinets, microscopes, lab tables and other equipment.
All major operations are required to be carried out in biosafety cabinets, and the biosafety cabinet equipment must maintain negative pressure during operation and be directly connected to the roof to ensure safety during the experiment.
These equipment not only require high-standard production, but also must be equipped with daily inspection staff, daily punctual inspections and irregular spot checks. If there is no high-load high-load use of equipment, it must be maintained strictly in accordance with the equipment maintenance cycle set by the software system. "
After answering the knowledge that she still remembered in her mind, Li Xiulan saw that the supervisor in front of her was still smiling, as if listening to her answer, and immediately made up a very quick-witted answer: "I Before applying for the promotion assessment, I took a special course. 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, and 7 of the doors are interlocked. In other words, if the previous door is not closed properly during entry, the next door will definitely not be opened, which can avoid microbial bacterial contamination caused by air circulation to a greater extent.
In the case of complicated door lock design, the design of the dressing area is also very complicated. In addition to the outer dressing room, shower room and inner dressing room, our Jiuzhou Technology's P4 laboratory also has a special bathroom for personal hygiene and cleaning. But I don't know what the difference is in the design here.
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 disinfection tank, fumigation room or ventilation transfer window with disinfection device on the wall of the main laboratory for transfer or disinfection.
The design of the disinfection area is not ordinary spray disinfection, but generally a chemical shower room, requiring laboratory staff to first use a chemical shower to disinfect the surface of the positive pressure protective clothing when leaving the main laboratory..."
As if answering a question that "makes sense, you can get points", Li Xiulan almost racked her brains to recite all the relevant information about the P4 laboratory in her mind.
In order to satisfy the supervisor in front of her, she even gave some oral answers and feedback on the use of equipment based on her previous work experience and insights from working in a lower-level laboratory.
"Of course, I personally think that these cumbersome and complex designs will take some time for every researcher entering the laboratory, but the P4-level biological laboratory is like a cage that holds the most terrifying demon in the world. It is not too much to enter and exit here, no matter how cumbersome and cautious it is.
Supervisor..."
After hearing this answer, Wang Haiping nodded slightly.
"Well, you have learned the basic knowledge very solidly, but it seems that you don't master it flexibly. You 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 to build a biological laboratory with us, he told us that as staff members of the biological laboratory, we enjoy high benefits and high wages, but at the same time we also have higher and heavier responsibilities."
