A sterilization record has to answer four questions for every load: which sterilizer, which cycle, what the monitoring showed, and who released it. Clinics that log only a date and a tick cannot reconstruct a load when an auditor or a patient question arrives. The 24-hour self-contained biological indicator, 50 per pack supplies the result that anchors the record.
What has to be written down for every cycle?
Record the date and time the cycle started, the sterilizer identifier, the cycle type and number, the temperature and pressure reached, the exposure time, the chemical indicator result, the biological indicator result and its incubation start, and the name of the person who released the load. If a load is quarantined pending a BI result, note the hold and the release time. Free-text notes belong in a comments field, not in place of the numbers.
| Field | Example entry | Why it matters |
|---|---|---|
| Sterilizer ID | Autoclave 2, serial 4471 | Isolates a fault to one unit |
| Cycle | Pre-vacuum, 134 C, 4 min | Matches the cycle to its validated parameters |
| Chemical indicator | Class 5 integrator, pass | Shows conditions inside the pack |
| Biological indicator | Lot 24-118, negative at 24 h | Anchors the release decision |
| Released by | Initials and time | Traceability for the release |
How often is a biological indicator required in Ontario?
In Ontario, the RCDSO requires a biological indicator for each sterilizer on every day it is used, with the result recorded in the log. That is daily monitoring, not weekly: the weekly baseline belongs to the CDC and AAMI ST79 guidance used in most US states. Dental teams that import a US template often plan for one spore test a week and end up with a quarter of the records their college expects. Outside Ontario, confirm the frequency with your own provincial college, because the requirement is set provincially and does vary.
How long should records be kept?
Retention is set by your college and by provincial record rules, so check the current requirement rather than copying a number from a course handout. In practice, most clinics keep cycle records and BI results for at least two years, and many keep them longer because a validation file supports equipment service history. Store them where a locum or an inspector can find them without asking, and keep the current year on paper at the sterilizer even if the archive is digital.
What happens when a record is missing?
A gap is treated as an unverified load. Find the affected packs if they are still on the shelf, quarantine them, and reprocess anything that cannot be traced. Then fix the cause: a clipboard that walks away, a printer that runs out of paper, or a log kept in two places. One page per sterilizer per month, signed at the end of the day, is more reliable than a binder that nobody owns.
Ordering for a clinic, lab or care home? Wholesale and multi-site ordering covers case pricing and account setup for facilities that buy by the month, and the B2B wholesale collection lists the lines stocked for institutional buyers. Reselling? become a distributor.
Print the sterilization log sheet, build a cycle record with the clinic supply planner, or ask a sterilization compliance specialist how the standard is applied in your province.
