Chapter 291: More Terrifying Than Ghosts and Gods.


    Biologicalboratories are scientific institutions dedicated to experimenting and researching pathogenic microorganisms.


    These institutions focus on studying pathogens, developing treatments and drugs, and providing protection for the safety of human lives. GfuM2t


    Biologicalboratories are divided into four biosafety levels based on the degree of biological risk of the research objects. Level oneboratories have the lowest requirements for biological safety istion, while level four has the highest.


    Level oneboratories work with pathogens that pose almost no harm to healthy adults, such as chickenpox. Personnel working in level onebs only need to wear gloves and facial protective equipment. Some workstations are open, and somebs may not even be isted from the public.


    Level twoboratories work with pathogens that only cause mild illnesses in humans. They typically have preventive and treatment methods, such as measles. Level twobs are isted from the public, and only authorized personnel can enter.


    Level threeboratories deal with pathogens that can cause severe or fatal diseases in humans and can spread through droplets. These diseases may have preventive and treatment methods, but constant vignce is required. For example, rabies, HIV/AIDS, and SARS coronavirus, an atypical pneumonia, which once ravaged the world and still make people frightened when mentioned, fall under level three. KaoAN


    Personnel conducting research and working in level threebs, even if experienced, must undergo specialized training for the pathogens beforehand. Theb must bepletely sealed and under negative pressure to prevent gas leakage.


    During experiments, rigorous protective measures must be taken. Personnel must wear protective clothing in the anteroom before entering theb, and all experiments must be conducted within biological safety cabs.


    Level threebs already have such strict safety precautions.Level threebs already handle pathogens at the level of HIV/AIDS and SARS. UD8njk


    Then, what about level fourbs?


    Level fourbs areboratories with the highest biosafety level globally.


    They handle pathogens that are little known to humans, extremely deadly, airborne, and have no preventive methods. Once infected, there is no cure for the pathogens.


    That’s why people also call level fourbs “Devil’s Lab.” 4r0svY


    Level fourbs need to bepletely isted from nearby buildings. They require special air conditioning systems with a filtration efficiency of 99.999%.
