Laboratory fume hood maintenance checklists

Laboratory fume hood maintenance checklists for the quarterly and annual rounds: 2 free lists, 10 items and 13 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against ANSI/AIHA Z9.5 (laboratory ventilation); the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule

Laboratory fume hood quarterly maintenance checklistquarterly
Every quarter, timed with the lab's exhaust and makeup air checks since a hood only pulls if the fan and the room air balance both hold. Run by: The facilities or lab maintenance tech on the quarterly round, with lab staff present in the working space.
Laboratory fume hood annual maintenance checklistannual
Once a year, scheduled with the certifier so the testing and the resulting certification sticker are witnessed and recorded before the hood is returned to service. Run by: The facilities lead documenting the visit while the qualified certifier performs the face-velocity and containment testing.

What most often fails on a laboratory fume hood

  • Sash routinely propped above the marked working height for a tall setup, so the hood is used well outside where it was set to contain.
  • Face-velocity monitor showing an alarm or a blank that staff have worked around for weeks instead of reporting it.
  • Boxes and bottles crowded against the rear baffle, blocking the airflow slots the hood depends on.
  • Certifier's measured values left on the sticker only, never copied into the facility record, so drift between years can't be seen.
  • Sash and baffles moved for testing and not returned to the marked working configuration, so day-to-day use no longer matches what was certified.

Verified against

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
