An autoclave does not go missing the way a drill does - it weighs as much as a filing cabinet and never leaves the room. What goes missing is its paperwork. The validation certificate is in a drawer, the last service report is in an engineer’s email, the daily test log is a steam-curled exercise book next to the machine, and the inspector wants all three for the specific steriliser in front of them. This guide covers a record system for autoclaves and sterilisation equipment that keeps every test, service and certificate attached to the machine it belongs to.

Why steriliser records fail audits
The machine itself is usually fine. What fails is the evidence:
- The logbook lives by the machine. Filled in daily, never backed up, exposed to steam and coffee. One lost book erases years of test history.
- Engineer reports live in inboxes. The service company emails a PDF to whoever booked the visit. When that person leaves, the report leaves with them.
- Several machines, one folder. A practice with two or three sterilisers ends up with certificates that say “autoclave” and no easy way to prove which serial number each one covers.
- One person holds the system together. The decontamination lead knows where everything is - right up until they hand in their notice.
An audit is rarely a test of the autoclave. It is a test of whether your records can be matched to a serial number on demand.
The autoclave register: what to record
One machine, one record, everything attached. The fields that earn their place:
| Field | Why it matters |
|---|---|
| Asset ID | One machine, one record - and what the label on the casing shows |
| Make, model + chamber size | Identifies the machine among several; the first thing a service engineer asks |
| Serial number | Ties every certificate and report to this machine, not to “the autoclave” |
| Location | Which room, which surgery, which site - obvious until you have three machines |
| Installation + purchase date | Starts the service clock and the warranty |
| Warranty end date | Decides whether the next repair is already paid for |
| Last + next validation date | The date an inspector checks first |
| Status | In use, in repair, retired - so a failed machine cannot quietly stay in service |
| Attached documents | Certificates, engineer reports, manuals and invoices on the record itself |

Labelling a machine that runs hot
A steriliser is a hostile place for a paper sticker, so choose placement and material deliberately:
- Pick a cool exterior surface. The side panel or frame, away from the chamber, the door seal and the vents. Never the door itself.
- Use polyester or laminated stock. The label has to survive heat radiating from the casing and daily wipe-downs with disinfectant.
- Print the asset ID beneath the QR code. The code opens the record from a phone camera; the printed ID is what gets read out over the phone to the service company.
- Label the accessories that wander. Trays, baskets and water-quality kit drift between rooms; a simple printed ID brings them home.
Tip: photograph the data plate the day the machine is installed and attach the photo to its record. Serial, model and pressure-vessel details fade with cleaning, and the engineer always needs exactly what is printed on that plate.
Daily tests, faults and service records
A steriliser generates more record-keeping than almost anything else in a practice, and all of it belongs on the machine’s own history:
- Routine tests as entries. Each steam-penetration or leak test gets a dated entry with the result and who ran it - a searchable history instead of a tick-grid in a book.
- Faults logged at the machine. A dropped seal or a failed cycle gets reported the moment it is spotted, with photos. The status flips to “in repair”, which is what actually stops someone running another load through a faulty machine.
- Service visits with paperwork attached. The engineer’s report and invoice go onto the same record, against the right serial number, the day of the visit.
Run the formal visits to a written inspection schedule rather than from memory - the gap between “serviced annually” and “serviced when someone remembered” is exactly what audits find.
Validation, downtime and end of life
Validation dates deserve the same prominence as warranty dates, because a steriliser with lapsed validation is, for compliance purposes, not a steriliser. Record the last and next dates on the register and book the engineer ahead of the deadline, not after it.
Plan for downtime too. A single-autoclave practice loses its ability to work the day the machine fails, so the register should make the machine’s age, fault frequency and repair costs visible early enough to budget a replacement calmly.
When a machine is retired, mark it retired rather than deleting it, and keep the full history through decommissioning. Questions about past sterilisation records can arrive years after the machine has gone.
Tools that make this easier
A spreadsheet can hold the inventory but not the evidence. Certificates stay in inboxes, test results stay on paper by the machine, and the link between a document and a serial number lives in someone’s memory - which is the exact failure an audit is designed to catch.
An asset management tool like AMPthilly keeps it in one place: each autoclave gets a profile with serial number, supplier, purchase and warranty dates, plus attached documents and images, so certificates and engineer reports live on the machine’s record. Printable QR labels open that record in any phone browser, faults are reported with photos through the service desk and stay on the machine’s history permanently, and the audit history logs every status change and edit. The free plan covers 3 users and 25 assets - enough for a practice’s sterilisers and the kit around them - and paid plans add the service desk and maintenance modules when you need them.
FAQ
What records should I keep for an autoclave? Asset ID, make and model, serial, location, installation and purchase dates, warranty end, full service and validation history, and the routine test log - with certificates and reports attached to the same record.
How do I keep an autoclave maintenance log? Every service, repair, validation and fault as a dated entry against the specific machine, with the paperwork attached to the entry rather than filed elsewhere.
Can I put a QR code on an autoclave? Yes - durable polyester or laminated stock, on a cool side panel away from the chamber and vents. Scanning it with a phone camera can open the machine’s record.
How long should autoclave records be kept? Check your regulator’s retention rules. The safe habit is the machine’s whole life and beyond - keep the record after decommissioning rather than deleting it.
What is the difference between user tests and validation? User tests are the routine between-service checks; validation is the periodic formal verification by a competent engineer. Inspectors expect to see both, on the same record.
The takeaway
Autoclave tracking is really evidence tracking. Give each machine one record under one asset ID, label it so the record is a phone-scan away, log tests and faults as dated entries, and attach every certificate and engineer report to the serial number it belongs to. Done that way, an inspection is a matter of opening the record - not a week of searching drawers and inboxes.
