The BSL-5 level biological laboratory of Infinite Gravity Group has determined a more dangerous level, that is, viruses and microorganisms that may endanger the survival of human beings. These viruses or microorganisms are the kind of viruses and microorganisms that have been radiated for a long time through various cosmic radiation environments. Existence after mutation.

If such a virus or microbe leaks out of the laboratory, it may really make humans go extinct. Refer to the science fiction movie "Resident Evil" for the specific degree of danger. If that tragic scene is accidentally in the future Is really possible!

Although neither Lei Tiantang nor the company's employees have the kind of brain-dead idea of ​​extinction, the high-risk virus really needs a better level of protection to make people feel at ease.

The previous BSL-4 laboratory did not allow the company's experts to study those highly infectious and lethal mutant viruses with confidence, because if this kind of thing really leaks out, they are really to blame. !

Let me first talk about the two BSL-4 experiments that the company has built for the biopharmaceutical company.

The two BSL-4 laboratory structures and facilities, safety operating procedures, and safety equipment are suitable for pathogenic microorganisms that are highly dangerous to the human body, and are transmitted through aerosols or unknown, and there is no effective vaccine or treatment method. And its toxins.

Contact with unknown microorganisms similar to the above situation must also be carried out in the BSL-4 laboratory. After sufficient data is available, it is decided whether such microorganisms or toxins should be processed in a BSL-4 laboratory or a lower-level laboratory.

Because of this, some people call the BSL-4 laboratory "the devil's laboratory". The BSL-4 laboratory is a "double-edged sword". Its application may benefit mankind, but it may also bring various things to mankind. "Scourge".

In recent years, the international community generally believes that the potential threat of biological weapons has greatly increased, and many countries have conducted such research. This is already an open secret, but it is not convenient to say more about this matter without evidence. In short This danger has always existed.

However, if there are omissions and accidents in the management of the BSL-4 laboratory, it can not only cause the infection of laboratory staff, but also cause environmental pollution and large-scale population infection.

Accidental infections in laboratories at home and abroad are not uncommon. In severe cases, thousands of laboratory animals have to be slaughtered, and even the death of laboratory staff. The more irregular the management and the worse the protection conditions, the possibility of accidents Bigger.

In order to solve the concerns of the company’s laboratory experts, the company has asked them to design a biological laboratory with a higher level of protection. Such a laboratory that allows them to work with peace of mind needs to be built even if the cost is high.

Even if Lei Tiantang had seen the mutant viruses and microorganisms that they were studying and planning to study, he would infinitely support them in designing and building a safer biological laboratory!

He felt that this was a terrible thing because he saw the deduction of the results of the virus leaked by artificial intelligence calculations, but he has to do this kind of research.

So they can only design and build a biological laboratory with a higher security level. Fortunately, after the biopharmaceutical company has built two BSL-4 laboratories, the company already has such laboratory technology. A very in-depth understanding.

Based on this technical standard, a more stringent BSL-5 laboratory was designed. This laboratory is equipped with a special air conditioning system. The temperature and humidity of the air entering here are preset, and the filtration degree reaches 99.99999%. Ensure that the air circulates multiple times in the entire environment within half an hour.

The laboratory adopts a directional negative pressure system, and the pressure in the core area reaches minus 50 Pa. In this way, the air flow in the laboratory can only come in from the outside through the high-efficiency filter, and the air in the laboratory does not flow out.

The laboratory consists of dressing area, filtering area, buffer zone, disinfection area and core area. HEPA filters are installed around the laboratory.

To reach the core area of ​​the laboratory, there are a total of 10 doors, and the innermost 7 doors are interlocked. That is to say, if one door is not closed properly, the other door will definitely not open, so as to avoid air circulation.

The dressing area is the outer dressing room, shower room and inner dressing room in sequence. The disinfection area is a chemical shower room. When the staff leave the main laboratory, they first go through the chemical shower to disinfect the surface of the positive pressure protective clothing.

There are automatic interlocking devices between any adjacent doors in the core area to prevent two adjacent doors from being opened at the same time. For materials, articles and equipment that cannot be carried in and out of the main laboratory from the changing room, an autoclave with a double-door structure, a immersion disinfection tank, a fumigation room or a ventilation transfer window with a disinfection device should be installed on the wall of the main laboratory For delivery or disinfection.

The core area is equipped with biological safety cabinets, ultra-low temperature refrigerators, centrifuges, electric cell culture cabinets, microscopes and experimental benches, small animal laboratories, etc. There is a thick pipe with a diameter of about 0.5 meters on the top of the biological safety cabinet, which leads directly to the roof. It is also under negative pressure. Some major operations need to be performed in the biological safety cabinet.

Related items taken from this BSL-5 laboratory must be sterilized in an autoclave, then fully packaged in a clean bag, and then passed to the preparation room through the transfer window.

When leaving the laboratory, the staff in the core area must disinfect each other from top to bottom before they can walk to the buffer room. Remove the outer protective clothing, masks, and outer gloves in the buffer room~lightnovelpub.net~ These are placed in a sterile container or sterile bag.

After closing the laboratory door, remove the protective glasses and put them in the transfer window for disinfection. Then, the staff went through another buffer room and retreated to the preparation room. Only here can they take off all the protective equipment on their bodies, and immediately after taking a bath in the shower room, can they leave the laboratory.

In order to ensure that there is absolutely no risk of virus leakage, the company's BSL-5 laboratory has more stringent and complex management procedures.

In order to ensure the absolute security of the BSL-4 laboratory, only those who have been approved and hold a magnetic card pass can enter, and some enter through the fingerprint access control system, and all personnel entering and exiting are recorded by the computer.

On this basis, the company's BSL-5 laboratory has also added an intelligent robot security and intelligent inspection link. The origin of artificial intelligence will also be paid attention to at any time. More than 30 emergency response plans are also controlled by it.

If there is a risk of mutated virus leakage, Origin will directly and intelligently combine appropriate countermeasures from the plan based on the situation on the spot, so as to ensure that there will never be a risk of leakage.
