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.
Microorganisms are grouped into four biosafety levels bsl.
The four biosafety levels corresponds to four risk groups.
Until more information becomes available precautions should be taken in handling specimens that are suspected or confirmed for sars cov 2.
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.
Timely communication between clinical and laboratory staff is essential to minimize the risk incurred in handling specimens from patients with possible sars cov 2 infection.
A biological safety cabinet bsc is the primary means of containment developed for working safely with infectious microorganisms.
Must be opened in the biosafety cabinet.
Class ii bscs the most common cabinets used in laboratories are designed to provide personnel protection for you and those around you product protection for your samples and environmental protection.
Biosafety level two would cover work with agents associated with human disease in other words pathogenic or infectious organisms posing a moderate hazard.
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.
A lower risk group can be assigned a higher biosafety level if a biological risk assessment carried out requires so.

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.
Containment requirements are subject to modification by the ibc at its discretion depending on the circumstances presented by a specific project.
