What are the principles of biosafety

What are the principles of biosafety level 2?
BSL-2 precautions are suitable for work involving agents that pose moderate hazards to personnel and the environment.
They are appropriate when work is done with any human-derived blood, body fluids, tissues, or primary human cell lines where the presence of an infectious agent may be unknown..

Laboratory biosafety practices are based on the principle of containment of biological agents to prevent exposure to laboratory workers and the outside environment. Primary containment protects the laboratory workers and the immediate laboratory environment from exposure to biological agents.

Biosafety Levels

The CDC/NIH has developed four biosafety levels that describe laboratory practices and techniques, safety equipment, and facility design features recommended for work with specific infectious organisms.
Descriptions of the biosafety levels, as well as assigned biosafety levels for specific organisms, are contained in the CDC/NIH document, Biosafety.

Containment

Laboratory biosafety practices are based on the principle of containment of biological agents to prevent exposure to laboratory workers and the outside environment.
Primary containment protects the laboratory workers and the immediate laboratory environment from exposure to biological agents.
Primary containment is achieved through good microbiolog.

What are laboratory biosafety practices?

Laboratory biosafety practices are based on the principle of containment of biological agents to prevent exposure to laboratory workers and the outside environment.
Primary containment protects the laboratory workers and the immediate laboratory environment from exposure to biological agents.

What is a biosafety level (BSL)?

Four biosafety levels (BSLs) represent combinations of laboratory practices and techniques, safety equipment, and laboratory facilities.
Each combination is specifically appropriate for the operations performed and the documented or suspected routes of transmission of the infectious agents, as well as for the laboratory function or activity.
