Chapter 874

The bsl-5 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 existence after long-time radiation mutation in various cosmic radiation environments.

If such viruses or microbes leak out of the laboratory, it may really make human extinct. For the specific risk level, refer to the science fiction film "biochemical crisis". If you are not careful, the tragic scene may happen in the future!

Although neither Lei Tiantang nor the employees of the company have the idea of killing the world with brain damage, the high-risk virus really needs better protection level to make people feel at ease.

The previous BSL-4 laboratory could not let the company's experts rest assured to study those highly infectious and lethal mutation virus, because if this kind of thing really leaked out, they would really die for it!

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

These two BSL-4 laboratory structures and facilities, safety operation procedures and safety equipment are suitable for pathogenic microorganisms and their toxins which are highly dangerous to human body, spread by aerosol or unknown transmission route, and have no effective vaccine or treatment.

Contact with unknown microorganisms similar to the above situation must also be carried out in BSL-4 laboratory. After sufficient data are available, it can be decided whether the microorganism or toxin should be treated in BSL-4 laboratory or lower level laboratory.

Because of this, some people call BSL-4 laboratory "devil's laboratory". BSL-4 laboratory is a "double-edged sword". Its application may benefit human beings, but it may also bring various "disasters" to human beings.

In recent years, the international community has generally believed that the potential threat of biological weapons has greatly increased. Many countries have conducted such research. This is an open secret. However, it is not convenient to say more about this matter without evidence. In short, such risks always exist.

However, if BSL-4 laboratory management omissions and accidents, not only can lead to laboratory staff infection, but also can cause environmental pollution and large-scale population infection.

Accidents of accidental infection in laboratories at home and abroad are not rare. In serious cases, thousands of laboratory animals have to be slaughtered, and even lead to the death of laboratory staff. The more nonstandard the management and the worse the protective conditions, the greater the possibility of accidents.

In order to solve the concerns of the company's laboratory experts, the company has asked them to design a biological laboratory with higher protection level. Such a laboratory that can make them work at ease needs to be built even though the cost is high.

Even after seeing the mutated virus and mutant microorganism that they submitted for research and plan to study, Lei Tiantang has unlimited support for them to design and build a safer biological laboratory!

He felt that it was a terrible thing to see the result deduction of virus leakage in the calculation of the origin of artificial intelligence, but this kind of research could not be ignored.

Therefore, they can only design and build a biological laboratory with higher security level. Fortunately, after two BSL-4 laboratories have been built by the biopharmaceutical company, the company has already had a deep understanding of such laboratory technology.

Based on this technical standard, a more strict bsl-5 laboratory is designed. The laboratory is equipped with a special air conditioning system. The air temperature and humidity entering the laboratory are preset, and the filtration degree reaches 99.9999%, which can ensure that the air circulates many times in half an hour in the whole environment.

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

The laboratory is composed of changing area, filtering area, buffer area, disinfection area and core area. High efficiency air filters are installed around the laboratory.

To the core area of the laboratory, there are 10 doors in total. 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 air circulation.

The changing areas were the outer changing room, the shower room and the inner changing room. The disinfection area is the chemical shower room. When the staff leave the main laboratory, they first disinfect the surface of positive pressure protective clothing by 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 the materials, articles and equipment that can not be brought in and out of the main laboratory from the changing room, high-pressure sterilization pot with double door structure, soaking disinfection tank, fumigation room or ventilation transmission window with disinfection device shall be set on the wall of the main laboratory for transmission or disinfection.

The core area is equipped with biosafety cabinet, ultra-low temperature refrigerator, centrifuge, electric heating cell culture cabinet, microscope and laboratory, small animal laboratory, etc. There is a thick pipe with a diameter of about 0.5m on the top of the biosafety cabinet, which directly leads to the roof. It is also in negative pressure state. Some major operations need to be carried out in the biosafety cabinet.The relevant items taken out from the bsl-5 laboratory must be sterilized in a autoclave, then packed in clean bags, and then transferred to the preparation room through the transfer window.

When leaving the laboratory, the staff in the core area should disinfect the whole body from top to bottom before they can walk to the buffer room. In the buffer room, the outer protective clothing, masks and gloves are removed, and then these are put into the sterilization container or bag.

After closing the laboratory door, remove the protective glasses and put them into the transfer window for disinfection. Then, the staff passed another buffer room and retreated to the preparation room. Only here can they take off all their protective equipment and take a bath in the bath room immediately before leaving the laboratory.

In order to ensure that there is absolutely no risk of virus leakage, the bsl-5 Laboratory of the company has more strict and complex management procedures.

In order to ensure the absolute security of BSL-4 laboratory, only those who have obtained the approval and hold the magnetic card pass can enter. Some of them can enter through the fingerprint access control system, and all the people in and out are recorded by the computer.

On this basis, bsl-5 Laboratory of the company has also added intelligent inspection link of intelligent robot security, and the origin of artificial intelligence will pay attention to at any time, and 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 site, so as to ensure that there is absolutely no risk of leakage.
