Studies:
What's biological danger
Biological hazard means a potential hazard from a biological factor when treated in a laboratory
New unknowns that may pose a potential biological hazard when dealing with the substance, or as a result of a genetic re-engineering process
Because of, or when dealing with, the results of the cause, these pathogens are likely to work with laboratories
People cause harm. When laboratory hardware conditions are missing, regulatory systems are inadequate and irregular

Operating procedures leading to leaks and escapes from laboratory causes. This could have disastrous consequences。
What's biosafety
Biosafety means avoiding exposure of laboratory personnel by dangerous biological factors and spreading outside the laboratory
And it leads to a comprehensive approach to harm。
What's a biosafety lab
Biosafety laboratory means the ability to avoid pathogen accidents while studying infectious diseases or microorganisms
The damaged lab
Main route of aerosol infection

Suction ball (i. E. Straw) operation. Suction is the most basic tool in microbiology
, which can cause aerosols to occur, e. G., by draining out of the straw, which can cause droplets to be pushed too hard
Splash, ejection from liquid or solid culture base surfaces, releasing large quantities of particles; or, when a straw tip
When the end contains material, it can produce bubbles, especially protein-rich suspensions. Gas
Bubbles, and bubbles break into aerosols. When the centrifugal sank, the silhouette was overloaded

The lid or not, and the fracture of the centrifugal tube during the operation of the centrifugal operation, can cause aerosols to disperse
Play。
Main route of aerosol infection
When the syringe is operated, the syringe needle is released due to tremors when pumped or allocated liquid
