1, used for microbiology, biomedicine, biochemistry, animal experiment, gene recombination and biological products research using laboratory generally referred to as the biosafety laboratory.

2, biological safety laboratory by the main function and other laboratory test chamber and auxiliary function of occupancy.

3, biological safety laboratory must guarantee personal safety, safety, environment safety and security, waste sample can run long and safely, and also for the laboratory staff to provide a comfortable, and good working environment.

4, classification of biological safety laboratory

Lab grading

Handle object

Level 1

To human, animals and plants, or environmental damage is low, do not have to healthy adults, animal and plant pathogenic pathogenic factor.

The secondary

Harm to human, animals and plants, or medium environment or potentially dangerous pathogenic factor, for healthy adults, plants and animals and the environment will not cause serious harm. Effective prevention and treatment measures.

Level 3

Highly dangerous to human, animals and plants, or environment, through the analysis of aerosol makes serious or even fatal infectious disease, or harmful to plants and animals and the environment is highly pathogenic factor. There are usually preventive treatment measures.

Level 4

Highly dangerous to human, animals and plants, or environment, through aerosol transmitted or route of transmission is unknown, or unknown and dangerous pathogenic factors. No preventive treatment measures.

Description:

In the table 1, "/" said do not ask, noise in this table exclude the biological safety cabinet, animals, the noise of the isolator, such as including the above the noise of the equipment, the largest should not exceed 68 db (A)

2, level 3 biological safety laboratory relative to the atmosphere, the minimum pressure shall not be less than 30 pa, four biosafety laboratory Lord minimum relative to atmospheric pressure shall not be less than 50 pa -

3, for raising animals 3 biological safety laboratory, its minimum relative to atmospheric pressure shall not be less than 50 pa, animal level 4 biosafety laboratory relative to the atmosphere, the minimum pressure shall not be less than 60 pa

4, animal biosafety laboratory parameters should be consistent with GB14925-2001 the requirements of the laboratory animal environment and facilities
