Grading

 

    Each biosafety laboratory is divided into four levels based on the extent of the hazards of the microorganisms and their toxins that are being treated. Biosafety laboratories at all levels of protection requirements are as follows: a minimum, the highest four.

 

     The scope of application

 

    1. Level 1 biosafety laboratory laboratory structure and facilities, safety practices, safety equipment for health adults known to non-pathogenic microorganisms, such as teaching for the ordinary microbiology laboratory.

 

    2. Secondary Biosafety Laboratory Laboratory structures and facilities, safe operating practices and safety equipment are suitable for use with microorganisms of medium potential hazard to humans or the environment.

 

    3. Three bio-safety laboratory laboratory structure and facilities, safety practices, safety equipment for respiratory diseases mainly through the transmission of serious or even lethal pathogenic microorganisms and their toxins, usually have been the prevention of infection Vaccine. HIV research (except for serological tests) should be conducted in a tertiary biosafety laboratory.

 

    4. Level 4 bio-safety protection laboratory laboratory structure and facilities, safety practices, safety equipment suitable for the human body with a high degree of danger through the aerosol route of transmission or transmission unknown, there is no effective vaccine or treatment Pathogenic microorganisms and their toxins. Unidentified microorganisms similar to those described above must also be conducted in Level 4 biosafety laboratories. Until there is sufficient data before deciding whether such microorganisms or toxins should be treated in Level 4 or in lower-level laboratories. The experimental vertebrate biosafety laboratory has the same range of applicable microorganisms as the generic biosafety laboratory at the same level.
