Biosafety cabinet preventive maintenance checklist

If you suspect HEPA filter damage, immediately restrict use of the cabinet and label it as potentially compromised. Document your findings using the checklist and contact a certified technician for professional assessment. Never attempt to repair HEPA filters yourself as improper handling can release contaminants. The cabinet will require decontamination and filter replacement by qualified personnel before returning to service.

Maintain a comprehensive record system including completed inspection checklists, certification reports, repair documentation, and incident logs. Store the cabinet manual, performance specifications, and NSF/ANSI 49 compliance documents. Keep records of filter changes, decontamination procedures, and calibration certificates for measuring equipment. These documents demonstrate regulatory compliance and provide crucial historical performance data for troubleshooting.

This checklist serves as a proactive tool to identify potential issues before formal certification. Regular inspections help detect problems with airflow, filter integrity, and cabinet components that might cause certification failure. By addressing minor issues early through routine maintenance, you reduce the risk of unexpected certification failures, minimize laboratory downtime, and avoid costly emergency repairs or decontamination procedures.
