A monthly autoclave checklist should cover the chamber, door gasket, filters, water supply, sealer and the records that prove each task was done. Preventive maintenance is tracked separately from daily monitoring, and both streams have to survive an audit. The checklist earns its keep when it names the task, the frequency, the person responsible and the evidence kept on file.
What should a monthly autoclave checklist cover?
A monthly checklist covers the parts that wear slowly and fail quietly. Inspect the door gasket for cracks, hardening and residue, and replace it on the manufacturer's schedule or sooner if it leaks. Check the chamber and door for scale or corrosion, and confirm the drain strainer is clear. Test the water supply against the sterilizer specification, since drift here shows up as staining and failed indicators. Verify the printer or cycle-record function, so a machine that passes today still produces evidence tomorrow. For sealing equipment, confirm the temperature and inspect a seal sample. Each of these tasks is quick, but together they catch the faults that daily monitoring only reveals after a load has already failed.
What does a pouch sealer calibration check involve?
A monthly sealer check confirms that the sealing bar holds its set temperature and that seals come out continuous and the right width. Run a seal on scrap material and inspect it for channels, wrinkles and incomplete welds, then compare it against the sealer's own temperature reading or an external check where available. If the seal shows gaps or the temperature drifts, the unit needs service before it produces another pack. Because a faulty sealer contaminates everything it seals, this check belongs on the same monthly sheet as the sterilizer tasks. Record the seal temperature and the outcome, not just a tick, so a reviewer can see what was verified.
How should the monthly checklist be structured?
A checklist works when each line states the task, the cadence, who owns it and where the proof lives.
| Task | Frequency | Owner | Evidence |
|---|---|---|---|
| Door gasket inspection | Monthly | Sterilization lead | Signed checklist line |
| Chamber and drain clean | Monthly | Clinical assistant | Signed checklist line |
| Water quality check | Monthly | Facility manager | Reading and date |
| Sealer seal sample | Monthly | Sterilization lead | Seal temperature and sample |
| Record review and filing | Monthly | Practice manager | Signed review note |
How do you keep maintenance records audit-ready?
Keep preventive maintenance in its own log, separate from the daily cycle and monitoring records, but store the two so they can be read together. Every line should show the date, the task, who did it and any corrective action, because a tick with no detail tells a reviewer nothing. Where a part is replaced, note the part and the date so the next interval can be calculated. File service reports and water-test results with the monthly sheets rather than in a separate folder. When an inspector asks how the sterilizer has been maintained, you should be able to hand over a single, dated series rather than reconstructing a story from scattered notes.
Tools that support the schedule
A few consumables make the monthly routine faster. A constant-heat pouch sealer holds its temperature for consistent seals, and a Bowie-Dick daily vacuum check pack keeps the air-removal column current between maintenance visits. Logging them against the same monthly sheet keeps the whole sterilization record in one place.

Frequently Asked Questions
How is preventive maintenance different from daily monitoring?
Daily monitoring records each cycle and its indicators. Preventive maintenance tracks scheduled service such as gaskets, filters and sealing checks on a longer interval.
Should the autoclave maintenance log be paper or digital?
Either works if it is dated, signed and retrievable. What matters is that each task shows who did it and when, with any corrective action noted.
What happens if a monthly maintenance task is missed?
Record the gap, complete the task as soon as possible and note the corrective action. Hidden gaps look worse to an auditor than a documented, resolved miss.
