An Ontario sterilization log has to answer one question load by load: which instruments went through which cycle, and what evidence shows that cycle worked. That means a load identifier, the sterilizer, the cycle type, the chemical indicator result, the biological indicator result for that sterilizer on that day, and the person who released the load. A log with those fields survives an inspection even when something went wrong, because it shows what was done and who decided it. A log without them fails even when nothing went wrong, because it cannot be tied to a specific set of instruments.
| Field | Why the auditor wants it | Common gap |
|---|---|---|
| Date and time of cycle | Places the load in the working day | Date only, no cycle time |
| Sterilizer identifier | Ties the record to one machine's history | One log for several sterilizers |
| Cycle type and number | Distinguishes wrapped from unwrapped, gravity from pre-vacuum | Cycle number missing |
| Load identifier | Links the record to specific instruments | No load number at all |
| Chemical indicator result | Per-package evidence of process variables | Recorded as "pass" without the indicator class |
| Biological indicator result | Evidence of kill for that sterilizer that day | Result filed on a separate sheet, untraceable |
| Releasing initials | Identifies who made the release decision | One signature for a whole week |
How often must a biological indicator be run in Ontario?
For each sterilizer, on every day that it is used, and for each type of cycle used. In Ontario, the RCDSO requires a biological indicator for each sterilizer on every day it is used — daily monitoring, not weekly. The weekly baseline is the CDC / AAMI ST79 standard in most US states, and that difference is the single most common source of confusion when a clinic compares its practice with a US training video. If a sterilizer runs one emergency load on an otherwise quiet day, that day still needs a test, because the requirement follows use rather than volume.
What else belongs in the same record?
The pouches themselves carry the first line of evidence: the CliniEco Sterilization Pouch — Class 4 self-sealing, dual indicator prints an internal and external reading on each pouch, so the per-package column in the log is quick to fill honestly.
The air removal test where the sterilizer type requires one, the results of any routine service, and a note of the corrective action when a biological indicator comes back positive. Keeping those on the same sheet as the daily results is what turns a stack of paper into a history: an auditor can follow a machine from routine monitoring through a failure and back to normal operation without asking for a second folder. The CliniEco Medical Bowie-Dick Test Pack — ISO 11140-5 Type 2 is the documented air-removal check for pre-vacuum cycles, and its result belongs in that same record.
How long should records be kept, and in what form?
Follow the retention period your regulator and your facility's own policy set, and keep the record in a form you can produce in the room where the sterilizer is. A binder that lives in the sterilization area and is filled in at the point of release beats a spreadsheet that is updated at the end of the week, because the point of release is the moment the decision is actually made. If the record is electronic, the same fields apply and the audit trail should show who entered the result and when — a spreadsheet with no author history is weaker evidence than a signed sheet.
What are the first four questions an inspector asks?
Show me the biological indicator results for the days the sterilizer was used. Show me how you know which instruments were in that load. Show me what you did after the last positive test. Show me who released the loads and what they were trained on. Every one of those questions is answered by the log if the log was designed around the load rather than around the cycle — and every one of them exposes a log that only records that a machine ran.
How should a log be set up so it survives a bad week?
Give every line a place to record the abnormal, not only the normal: a column for the corrective action and a column for who authorised the resumption. When a positive test happens, the sheet then documents the response instead of leaving a gap that looks like negligence. Pair the biological indicator with the per-package chemical result — the CliniEco Sterilization Pouch — Class 4 self-sealing, dual indicator prints an internal and external reading on each pouch, which makes the per-package column quick to fill honestly. Label packages with the cycle date and load number using a writable indicator tape such as the CliniEco Medical Autoclave Indicator Tape, and keep the biological indicators for the same day's testing in the same binder.

The sterilization compliance hub collects the related guides. For ordering indicators and pouches, wholesale and multi-site ordering covers account setup and case pricing, and the B2B wholesale collection lists the lines stocked for clinics. If your record has a gap you cannot reconstruct, ask a sterilization compliance specialist. Reselling? become a distributor.

Frequently Asked Questions
Does an Ontario clinic need a biological indicator every day the sterilizer is used?
Yes, for each sterilizer and for each type of cycle used that day. That is daily monitoring; the weekly schedule commonly quoted in US guidance is a different baseline and should not be applied to an Ontario practice.
Can the daily biological result be kept on a separate sheet?
It can be kept separately only if it can be tied to the same load record without guesswork. In practice an auditor wants one page that shows the cycle, the load and the biological result together, so filing them apart usually creates the finding.
What should be recorded when a biological indicator is positive?
The date and sterilizer, the loads affected, the quarantine decision, the corrective action taken, the retest result, and who authorised resuming use. A gap between a positive result and normal operation is the finding.
Is an electronic log acceptable in place of paper?
Yes, provided it captures the same fields and shows who entered each result and when. An electronic record without an author history is weaker than a signed sheet.
