Frequently asked questions
Can infectious samples be handled in a laminar-flow clean bench?
A clean bench is not intended to protect the operator from hazardous aerosols. A competent biosafety professional should select the correct containment device.
Does a biosafety cabinet need certification?
Yes. Certification and periodic performance verification are critical to confirm airflow and filter performance.
Is a fume hood the same as a biosafety cabinet?
No. A chemical fume hood is designed for chemical vapour control, while a BSC is selected for biological containment.
