I have a little black hole

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

If such a virus or microorganism leaked out of the laboratory, it might really make humans extinct. The specific degree of danger is known by referring to the science fiction movie "Resident Evil". If the tragic scene is accidental in the future Words can really happen!

Although neither Lei Tiantang nor the company’s employees have the kind of brain-destructive idea of ​​extinction, the high-risk virus really needs a better protection level 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 leaked out, they would really be blamed for their deaths. !

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

The two BSL-4 laboratory structures and facilities, safe operating procedures, and safety equipment are suitable for pathogenic microorganisms that are highly dangerous to the human body, are transmitted by aerosol or whose transmission route is 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 conducted in the BSL-4 laboratory.After sufficient data is available, decide whether such microorganisms or toxins should be processed in the BSL-4 laboratory or a lower-level laboratory.

Because of this, some people call the BSL-4 laboratory "Devil's Laboratory". The BSL-4 laboratory is a "double-edged sword". Its application may benefit mankind, but if it is not done well, it may also bring all kinds of 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 Such dangers always exist.

If the BSL-4 laboratory has omissions and accidents in management, it can not only cause infections of laboratory workers, but also cause environmental pollution and infection of large areas of the population.

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

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

Even after Lei Tiantang saw the mutant viruses and mutant microorganisms they were studying and intending to study, they infinitely supported them in designing and building a safer biological laboratory!

Seeing the results of the virus leaks from the calculation of the origin of artificial intelligence, he felt that this was a terrible thing, but this kind of research had to be done.

So they can only let them design and build a biological laboratory with a higher safety level. Fortunately, after the construction of two BSL-4 laboratories on the side of the biopharmaceutical company, the company has already had such laboratory technology. A very deep understanding.

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

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

The laboratory consists of dressing area, filtration area, buffer zone, disinfection area and core area.High efficiency air filters are installed around the laboratory.

There are a total of 10 doors in the core area of ​​the laboratory, and the inner 7 doors are interlocked. That is to say, if one door is not closed properly, the other door cannot be opened, so as to avoid the circulation of air.

The changing area is the outer changing room, shower room and inner changing room in sequence.The disinfection area is a chemical shower room. When the staff leaves the main laboratory, the surface of the positive pressure protective clothing is disinfected by the chemical shower.

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 into or out of the main laboratory from the dressing room, a high-pressure sterilizer with a double door structure, a immersion sterilization tank, a fumigation room or a ventilation transmission 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, electrothermal cell culture cabinets, microscopes and laboratory benches, small animal laboratories, etc.There is a thick pipe with a diameter of about 0.5 meters on the top of the biosafety cabinet, which directly leads to the roof. It is also in a negative pressure state, and some major operations need to be performed in the biosafety cabinet.

The related items taken out from this BSL-5 laboratory must be sterilized by an autoclave, then fully packed in clean bags, and then passed through the transfer window to the preparation room.

When leaving the laboratory, the staff in the core area must disinfect each other from top to bottom before going to the buffer room, remove the outer protective clothing, masks, and outer gloves in the buffer room, and then put these into a sterilization container Or inside a sterilization bag.

After closing the laboratory door, remove the protective glasses and place them in the delivery window for disinfection.Then, the staff passed another buffer room and retreated to the preparation room.Here they can take off all protective equipment on their bodies and leave the laboratory immediately after taking a shower in the shower room.

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

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

The company's BSL-5 laboratory also adds an intelligent robot security inspection link on this basis. The origin of artificial intelligence will also be concerned at any time. More than 30 emergency response plans are also controlled by it.

If there is a risk of mutation virus leakage, the origin will directly and intelligently combine appropriate response measures from the plan according to the situation on the spot, thereby ensuring that there will never be a risk of leakage.
