18
Q

What is a Biological Safety Cabinet (BSC)?

A

A ventilated, enclosed workspace used in laboratories to handle biological agents safely.

It provides protection for the user, the environment, and the sample by controlling airflow and filtering contaminants.

19
Q

What does a Biological Safety Cabinet prevent?

A

Aerosol transmission of infectious agents.

It also protects lab workers from exposure to pathogens and ensures sterility of cultures and diagnostic samples.

20
Q

What are some pathogens that require a Biological Safety Cabinet for handling?

A

SARS-CoV-2, TB, and Hepatitis B.

These are considered hazardous biological agents.

21
Q

What type of protection does a Class I Biological Safety Cabinet provide?

A

Protects the user and the environment, but not the sample.

Used for low-to-moderate risk biological agents.

22
Q

Provide an example of when a Class I Biological Safety Cabinet might be used.

A

Handling bacterial cultures in teaching labs.

23
Q

What type of Biological Safety Cabinet is most common in medical labs?

A

Class II.

It protects the user, the environment, and the sample.

24
Q

What feature does a Class II Biological Safety Cabinet use to maintain sterile airflow?

A

HEPA filters.

25
Give an example of a situation where a Class II Biological Safety Cabinet would be necessary.
Handling COVID-19 samples or TB cultures.
26
What is the highest level of protection provided by a Biological Safety Cabinet?
Class III. ## Footnote It is fully sealed and glovebox-type.
27
What type of pathogens is a Class III Biological Safety Cabinet required for?
High-risk pathogens (Risk Group 4: Ebola, Lassa fever).
28
In what type of laboratories is a Class III Biological Safety Cabinet used?
Biosafety level 4 (BSL-4) laboratories.
