Biosafety cabinet maintenance checklist

First, clearly document the issue with photos if possible. For minor issues like surface contamination, follow your lab’s cleaning protocols. For performance concerns (abnormal airflow readings, unusual noises), immediately tag the cabinet as “Out of Service,” notify your supervisor, and contact your certified BSC technician for professional assessment.

The primary cabinet users and lab safety officers should share responsibility for regular maintenance checks. Assign specific personnel for daily and weekly checks, while monthly inspections might be conducted by supervisory staff. This creates accountability and ensures maintenance tasks aren’t overlooked during busy laboratory operations.

Use properly calibrated instruments designated for your specific cabinet model. Record readings at the same locations each time following manufacturer guidelines. Take multiple measurements and calculate the average for greater accuracy. Consistent methodology helps identify gradual changes that might indicate developing problems with HEPA filters or blower motors.

Regular maintenance using this checklist helps identify minor issues before they cause major damage. Pay special attention to keeping the drain pan clean, monitoring filter pressure differentials, and ensuring proper airflow. These practices reduce strain on motors, prevent corrosion of internal components, and maintain optimal performance for years longer.
