Lab Fume Hood Certification Scheduler
A free fume hood maintenance register: last service, interval, due date and overdue alerts — sorted by urgency, stored in your browser.
Your register stays in this browser (localStorage) — nothing is uploaded.
Add your first fume hood to see the schedule. Sorted by urgency, the next due item is always on top.
Field notes from maintenance practice
Between certifications, the cheap insurance is a continuous airflow monitor (or at minimum a tissue-strip telltale) plus a marked maximum sash height: most containment failures are operational — sash wide open, hood used as storage, or a renovated room that starved the exhaust — and they happen the week after the certificate, not before it. The register line should carry the certified face velocity and sash height so drift is checkable by anyone.
Lab freezers and biosafety cabinets carry their own certification lines — give each engineered control its own row; 'the lab was certified' hides which device wasn't. Run the register on whatever device lives where the work happens — a workshop tablet beats a spreadsheet on someone's laptop, because the person doing the job sees the list.

About Lab Fume Hood Certification Scheduler
This scheduler keeps a living register of your fume hoods: add each one with its last service date and interval, and the board computes due dates, sorts by urgency and flags anything overdue or due within 14 days. One tap (✓) marks a service done and restarts that asset's clock. Lab safety practice (ANSI/ASSP Z9.5; ASHRAE 110 test method) calls for fume hoods tested and certified at least annually — face velocity profile, smoke visualisation and, where required, tracer-gas containment.
How to use Lab Fume Hood Certification Scheduler
- 1Add each asset with its last service date and interval — presets reflect the cited standard, and you can override per asset.
- 2The register sorts itself by urgency: overdue first, then due-soon (≤14 days), with a badge per asset.
- 3Tick ✓ when a service is done to reset that asset's clock to today — the whole register persists in your browser.

Frequently asked questions
How often should a fume hood be serviced or inspected?+
Lab safety practice (ANSI/ASSP Z9.5; ASHRAE 110 test method) calls for fume hoods tested and certified at least annually — face velocity profile, smoke visualisation and, where required, tracer-gas containment. Severe duty, harsh environments or regulatory requirements shorten it — and your OEM manual, insurer or local code always takes precedence over the generic default.
What face velocity should my hood certify at?+
Typically 80–120 fpm (0.4–0.6 m/s) at the designated sash opening, with 100 fpm the classic target — but the right answer is your institution's EHS specification and the hood's design: high-performance hoods certify at 60–80 fpm by design, and excessive velocity causes turbulence that worsens containment. The ASHRAE 110 tracer test, not velocity alone, is the true containment proof; velocity is the daily proxy. Record the certified figure per hood in its register line.
Calendar-based or usage-based — which scheduling is right here?+
Calendar scheduling suits fume hoods because the dominant ageing mechanisms (seals drying, contamination, regulatory clocks) run on time, not duty. If a unit works double shifts, shorten its interval rather than switching methods — this register lets you set a different interval per asset.
Where is my register stored — can my team see it?+
Everything lives in this browser's localStorage: private, instant and free, with nothing uploaded. That also means it's per-device — for a shared team register, run it on the workshop's common tablet/PC, or export key dates into your team calendar. For audit-grade multi-user history you'd graduate to a full CMMS.
