universal biosafety mesures

Hello!!!

Today, I am goning to talk about the universal biosafety mesures, because is a topic very interesting for me and it is my topic in the work for Introductions to the living agents of the disease!!!

well, the biosafety is the level of the biocontainment precautions required to isolate dangerous biological agents in an enclosed facility. The levels of containment range from the lowest biosafety level 1 to the highest at level 4.
Levels

Biosafety level 1
This level is suitable for work involving well-characterized agents not known to consistently cause disease in healthy adult humans, and of minimal potential hazard to laboratory personnel and the environment. It includes several kinds of bacteria and viruses including canine hepatitis, non-pathogenic Escherichia coli, as well as some cell cultures and non-infectious bacteria. At this level precautions against the biohazardous materials in question are minimal, most likely involving gloves and some sort of facial protection.

Biosafety level 2
This level is similar to Biosafety Level 1 and is suitable for work involving agents of moderate potential hazard to personnel and the environment. It includes various bacteria and viruses that cause only mild disease to humans, or are difficult to contract via aerosol in a lab setting

Biosafety level 3
This level is applicable to clinical, diagnostic, teaching, research, or production facilities in which work is done with indigenous or exotic agents which may cause serious or potentially lethal disease after inhalation.

Biosafety level 4
This level is required for work with dangerous and exotic agents that pose a high individual risk of aerosol-transmitted laboratory infections, agents which cause severe to fatal disease in humans for which vaccines or other treatments are not available.

Well, this is the Universal Biosafety Mesures and is very important for the manipulation of the injurious agents for the health.

Good Bye.
