Biosafety cabinet levels ppt.
Biosafety level two would cover work with agents associated with human disease in other words pathogenic or infectious organisms posing a moderate hazard.
A biosafety cabinet bsc also called a biological safety cabinet or microbiological safety cabinet is an enclosed ventilated laboratory workspace for safely working with materials contaminated with or potentially contaminated with pathogens requiring a defined biosafety level several different types of bsc exist differentiated by the degree of biocontainment required.
A biological safety cabinet bsc is the primary means of containment developed for working safely with infectious microorganisms.
Microorganisms are grouped into four biosafety levels bsl.
A lower risk group can be assigned a higher biosafety level if a biological risk assessment carried out requires so.
Risk assessment risk assessment constitutes the basis for the safeguards developed by different organizations such as the microbiological and biomedical community to protect the health of laboratory workers and the public from the risks associated with the use of hazardous biological agents in laboratories.
The ibc uses the biosafety levels recommended by the cdc and nih as the usual standards of containment to be set for work with a given biohazardous material.
Must be opened in the biosafety cabinet.
Biosafety is the application of safety precautions that reduce a laboratorians risk of exposure to a potentially infectious material and limit contamination of the work environment and ultimately the community cdc 4.
Until more information becomes available precautions should be taken in handling specimens that are suspected or confirmed for sars cov 2.

Powerpoint slide on biosafety compiled by monika saini.
Preferably this is a class ii biosafety cabinet or equivalent containment device for work with agents and an autoclave or other suitable method for decontamination within the lab.
The four biosafety levels corresponds to four risk groups.
Biosafety level i.
Increasing levels of personnel and environmental protection guidelines for working safely in microbiological and biomedical laboratories work at bsl 3 biosafety levels.
Bsl 1 bsl 2 bsl 3 bsl 4 each level involves.
