Introduce Biosafety protection level 3 laboratory
III biosafety protection laboratory, referred to as P3 laboratory, P stands for Physical containment. The whole laboratory is completely sealed and the room is under negative pressure, so that the gas inside the laboratory will not leak to the outside and cause pollution.
Laboratory biosafety protection laboratory refers to the structure and facilities of the laboratory, safe operating procedures, safety equipment to ensure that the staff in the treatment of pathogenic microorganisms and their toxins, not infected by the experimental object, the surrounding environment is not contaminated. According to the harm degree of microorganism and its toxin, it is divided into four levels, with the lowest level and the highest level. Biosafety protection level 1 laboratory is generally applicable to the healthy adult no pathogenic effect of microorganisms; Level 2 is for microorganisms with moderate potential for harm to people and the environment; Level 3 applies to pathogenic microorganisms or their toxins that transmit a serious or even fatal disease to a person primarily through breathing; Level 4 is applicable to pathogenic microorganisms or their toxins that are highly dangerous to humans, transmitted through aerosol or unknown, and for which there is currently no effective vaccine or treatment.
Biosafety Level 3 (BSL-3)BSL-3 is used in clinical, diagnostic, teaching, research, or manufacturing facilities to perform work at this level with respect to endogenous and exogenous pathogens that may be inhaled as a result of exposure. Can cause serious and potentially fatal illness. The experimenter should be professionally trained in dealing with pathogenic and potentially fatal causes and should be supervised by a qualified scientific worker experienced in working with the cause. All steps related to the operation of the source of infection are performed in a biosafety cabinet or other physical containment device, or by laboratory personnel wearing appropriate protective clothing and equipment.
