Question

What biosafety level is attributed to microbiological agents that pose high risk and may cause serious or lethal disease via inhalation but effective treatment is available; they require a biological safety cabinet (BSC) II, negative airflow, sealed windows, PPE, autoclave must be available, and limited access.

a) BSL-1
b) BSL-2
c) BSL-3
d) BSL-4

Answer 1

The appropriate biosafety level for microbiological agents that pose a high risk and may cause serious or lethal disease but have effective treatment available is BSL-3.

Step-by-step explanation:

The appropriate biosafety level for microbiological agents that pose a high risk and may cause serious or lethal disease via inhalation, but have effective treatment available, is BSL-3.

BSL-3 laboratories require a biological safety cabinet (BSC) II, negative airflow, sealed windows, personal protective equipment (PPE), and an autoclave must be available. Access to BSL-3 laboratories is limited, and they have additional precautions such as medical surveillance for laboratory workers and the use of a respirator.
