I Have a Little Black Hole

The BSL-5 biological laboratory of the 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 all types of radiation that have been exposed to various cosmic radiation environments for a long time. mutated existence.

If such a virus or microorganism leaks out of the laboratory, it may really cause human extinction. The specific danger level can be known by referring to the sci-fi movie Resident Evil. If the tragic scene is not careful in the future It could really happen!

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

The previous BSL-4 laboratory could not reassure the company's experts to study those highly infectious and lethal mutant viruses, because if this kind of thing really leaked out, they would really be blamed for their deaths. !

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

These 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, transmitted by aerosol route or the route of transmission is unknown, and there is no effective vaccine or treatment. and its toxins.

Contact with unknown microorganisms similar to the above must also be carried out in the BSL-4 laboratory. A decision on whether such microorganisms or toxins should be handled in a BSL-4 laboratory or in a lower level laboratory will be made after sufficient data are available.

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 bring all kinds of problems to mankind. scourge.

In recent years, the international community generally believes that the potential threat of biological weapons has greatly increased. Many countries have conducted such research, which is already an open secret. However, it is inconvenient to say more about this matter without evidence. Such dangers have always existed.

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

Accidental infections in laboratories at home and abroad are not uncommon. In severe cases, tens of thousands of experimental animals have to be slaughtered, and even laboratory workers are killed. The less standardized the management, the worse the protection conditions, and the possibility of accidents bigger.

In order to solve the concerns of the company's laboratory experts, the company 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 after Lei Tiantang saw the mutated viruses and mutated microorganisms they were researching and planning to study, he would infinitely support them in designing and building a safer biological laboratory!

Because he saw the deduction of the virus leakage results of 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 design and build a biological laboratory with a higher level of safety. Fortunately, after the biopharmaceutical company 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 is 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 many times in the whole environment for half an hour.

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

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

Arriving at 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 cannot be opened, so as to avoid the circulation of air.

The changing area is followed by the outer changing room, the shower room and the inner changing room. The disinfection area is a chemical shower room. When the staff leaves the main laboratory, they first go through the chemical shower to disinfect the surface of the positive pressure protective clothing.

There are automatic interlocks between any adjacent doors in the core area, preventing two adjacent doors from being opened at the same time. For materials, items and equipment that cannot be brought into and out of the main laboratory from the dressing room, an autoclave with a double-door structure, an immersion disinfection tank, a fumigation room, or a ventilation transfer window with a disinfection device should be installed on the main laboratory wall. , for delivery or disinfection.

The core area is equipped with biological safety cabinets, ultra-low temperature refrigerators, centrifuges, electrothermal cell culture cabinets, microscopes and experimental benches, and small animal laboratories. 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 in a negative pressure state, and some major operations need to be carried out in the biological safety cabinet.

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

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

After closing the laboratory door, remove the protective glasses and place them in the transfer window for disinfection. Then, the staff passed 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 take a bath in the shower room before leaving the laboratory.

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

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

On this basis, the company's BSL-5 laboratory has also added an intelligent robot security inspection link, and the origin of artificial intelligence will also be concerned at any time, and 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 according to the on-site situation, so as to ensure that there is absolutely no risk of leakage.
