Question

1) 15 min
2) 30 min
3) 45 min
4) 60 min

Answer 1

A laminar flow hood requires a 30-minute runtime after being turned off to establish a sterile environment for use.

Step-by-step explanation:

If a laminar flow hood is turned off, it should be turned on and allowed to run for at least 30 minutes before it is used to ensure that a proper sterile environment is reestablished.

Laminar flow hoods are used to create a clean air environment that is crucial for handling sterile products, such as in the preparation of injectable medications or in tissue culture work. It's essential that the hood runs for this length of time to flush out any contaminants that may have settled in the absence of the laminar flow.
