Biological Safety Cabinet Inspection Checklist [FREE PDF]

Biological safety cabinets (BSCs) are critical primary containment devices that protect laboratory workers, the environment, and research samples from biohazardous aerosols and splatter. OSHA 29 CFR 1910.1450 and NSF/ANSI 49 mandate routine inspection, certification, and documentation of BSC performance to ensure containment integrity. Failure to maintain certified BSCs can result in regulatory citations, compromised sample integrity, and serious occupational exposure incidents.

  • Industry: Laboratory Services
  • Frequency: Monthly
  • Estimated Time: 30-45 minutes
  • Role: Lab Safety Officer
  • Total Items: 33
  • Compliance: OSHA 29 CFR 1910.1450 - Occupational Exposure to Hazardous Chemicals in Laboratories, NSF/ANSI 49 - Biosafety Cabinetry: Design, Construction, Performance, and Field Certification, CDC/NIH Biosafety in Microbiological and Biomedical Laboratories (BMBL) 6th Edition, CAP Accreditation Standards - Laboratory General Checklist (GEN.73975), ISO 17025:2017 - General Requirements for the Competence of Testing and Calibration Laboratories

Certification & Documentation Status

Verify that the BSC has a current, valid certification and all required documentation is present and up to date.

  • Does the BSC have a valid certification label affixed from an accredited certifier within the past 12 months?
  • Is the most recent certification report retained in the BSC logbook or electronic records?
  • Has the BSC been recertified following any repair, relocation, or HEPA filter replacement?
  • Is the BSC logbook complete with all maintenance, decontamination, and usage entries?
  • Are SOPs for BSC operation, decontamination, and emergency procedures current and accessible to all users?

Physical Condition & Structural Integrity

Inspect the cabinet's physical components for damage, deterioration, or conditions that could compromise containment.

  • Is the sash free from cracks, chips, or damage that could compromise the UV-blocking or containment properties?
  • Are all cabinet interior surfaces (work surface, side walls, back panel) intact and free from cracks, rust, or pitting?
  • Are the front grille and rear plenum grilles unobstructed and free from debris?
  • Is the UV germicidal lamp (if present) functioning and has it been replaced within the manufacturer-recommended service interval?
  • Is the fluorescent lighting functioning properly with no flickering or burned-out bulbs?

Airflow & HEPA Filter Performance

Evaluate airflow velocity readings, alarm functionality, and HEPA filter condition to confirm containment performance.

  • Does the magnehelic or digital airflow gauge reading fall within the certified acceptable range documented on the certification label?
  • Is the airflow alarm (low-flow or sash-position alarm) functional and tested?
  • Is there visual evidence of HEPA filter loading, damage, or bypass (e.g., visible discoloration, unusual pressure differential readings)?
  • Has the cabinet been allowed to purge for the minimum required time (typically 5 minutes) before work began today?
  • Is the recorded airflow gauge reading within normal operational range?

Decontamination & Cleaning Practices

Confirm that proper decontamination procedures are followed before and after use and following any spill or potential contamination event.

  • Is the interior of the cabinet decontaminated with an appropriate disinfectant before and after each use?
  • Are gaseous decontamination records (e.g., formaldehyde or VHP fumigation) available prior to any HEPA filter change or major internal service?
  • Is an appropriate spill kit readily accessible within 10 feet of the BSC?
  • Are disinfectant solutions prepared at the correct concentration and within their documented expiration or use-by date?

User Work Practices & PPE Compliance

Assess whether BSC users follow correct aseptic and containment work practices to maintain both product and personnel protection.

  • Do all BSC users wear appropriate PPE (lab coat, gloves, eye protection) as required by the risk assessment for materials handled?
  • Are all manipulations performed at least 4 inches inside the cabinet, away from the front grille?
  • Is the cabinet kept free from clutter, with only materials required for the immediate task present inside?
  • Are arm movements slow and perpendicular (not sweeping or parallel) when entering and exiting the cabinet?
  • Are all users trained and documented as competent in BSC operation within the past 2 years?

Electrical & Mechanical Systems

Inspect electrical connections, blower motor, and other mechanical components for safe and proper operation.

  • Is the power cord in good condition with no fraying, kinking, or damage to the insulation?
  • Is the blower motor operating quietly without unusual vibration, rattling, or grinding noises?
  • Is the cabinet connected to a dedicated, grounded electrical circuit appropriate for its amperage requirements?
  • Is the exhaust connection (for Type B or externally exhausted cabinets) sealed, intact, and connected to the building exhaust system?

Deficiencies & Corrective Actions

Document any deficiencies identified during this inspection and assign corrective actions with responsible parties and target dates.

  • Were any deficiencies or non-conformances identified during this inspection?
  • Has the cabinet been placed out of service pending corrective action for any critical deficiency identified?
  • Describe all deficiencies identified and corrective actions assigned, including responsible party and target completion date.
  • Has this inspection been reviewed and approved by the Laboratory Safety Officer or designee?
  • Additional inspector notes or observations not captured above.
