Does ISO 45001 require calibration?

Yes, where equipment is used to evaluate OH&S performance. Clause 9.1.1 expects monitoring and measuring equipment to be calibrated or verified as applicable, used and maintained as appropriate, and backed by retained documented information covering both the measurement results and the calibration or verification of the equipment itself. The standard names no specific tool. Axiospec provides the tracking and records; it does not certify your conformance.

Which instruments does ISO 45001 clause 9.1.1 cover?

Any equipment whose readings feed OH&S performance evaluation: gas detectors, noise dosimeters, air sampling pumps, vibration meters, thermal stress monitors, and pressure or torque tools used on safety-critical fittings. If a reading from the instrument informs an exposure decision or a control check, the instrument needs a known, current calibration status and retained evidence behind it.

What calibration records should an ISO 45001 audit see?

Evidence that each monitoring instrument was calibrated or verified: who performed it, when, the readings, the reference standard used, and the current status, plus evidence of maintenance. Axiospec logs each calibration with attribution and timestamps in a tamper-evident ledger, keeps the reference standard and certificate on the asset, and exports an audit pack for one instrument or your whole registry from the Audit Center.

Is Axiospec a good fit for a small EHS team?

Yes. The free plan is the full platform capped at 50 active assets with unlimited users, which covers the monitoring equipment file of many EHS programs without a paid tier. Technicians can log from the field with the mobile app, offline if needed, and the Due Calendar keeps detector and dosimeter due dates visible. Axiospec keeps the records clause 9.1.1 expects; it does not certify conformance, which your auditor determines.

Does Axiospec force technicians to fill in every required field?

Yes, by default. When you select a standard, the fields that standard requires are marked on the calibration form and the save is blocked until they are filled. Enforcement is on for every workspace unless an admin turns it off in Settings. There is one deliberate exception. A brand new workspace is not held to the standard fields until it has logged its first calibration, so a first run is never trapped behind a form it cannot save. Full strictness applies from the second calibration onward. The public REST API enforces the same requirements on write.

For EHS & safety teams

Calibration documentation for ISO 45001 clause 9.1.1

ISO 45001 is the international standard for occupational health and safety management systems. Most of it is about hazards, risk, and worker participation rather than calibration, but clause 9.1.1 puts a firm expectation on the equipment you use to evaluate OH&S performance: gas detectors, noise dosimeters, air sampling pumps, and pressure or torque tools only give trustworthy readings when they are calibrated and in date. The checklist below shows where calibration lives in the standard. Axiospec keeps that safety-critical monitoring equipment tracked, current, and documented so the measurements behind your OH&S decisions rest on instruments you can stand behind.

ISO 45001 clause 9.1.1 calibration checklist

9.1.1: Calibrate or verify monitoring equipment

Where monitoring and measuring equipment is used to evaluate OH&S performance, ensure it is calibrated or verified as applicable, and used and maintained as appropriate.

9.1.1: Retain the evidence

Retain documented information as evidence of the monitoring, measurement, analysis, and evaluation results, and of the maintenance, calibration, or verification of the measuring equipment itself.

6.1.2: Hazard identification and assessment of risks and opportunities

OH&S risks and opportunities must be identified and assessed, which often relies on exposure measurements (gas, noise, dust, vibration) that are only meaningful when taken with equipment of known, current calibration status.

8.1: Operational planning and control

Controls put in place to eliminate hazards and reduce OH&S risks have to be planned, implemented, and maintained, including the instruments those controls depend on to confirm exposures stay within limits.

How Axiospec helps ISO 45001 teams

Due dates you can see coming

Set a calibration interval per gas detector, dosimeter, sampling pump, or torque tool and let Axiospec surface what is due and overdue, with reminders before each date. Axiospec does not lock out or prevent use of any instrument.

Calibration status on every monitor

Each instrument carries a live status (in tolerance, due, overdue, or quarantined) so a technician can confirm a monitor is fit for use before they rely on its reading in the field.

Retained evidence for clause 9.1

Every calibration is logged with who, when, the readings, and the reference standard used, giving you the calibration records behind clause 9.1, ready to export as an audit pack.

Capture readings anywhere, even offline

Log calibrations and checks from any web browser or from the mobile app while offline in a plant or remote site, then sync, so field monitoring equipment stays documented without a trip back to a desk.

Calibration software for ISO 45001 clause 9.1.1 requirements

ISO 45001 puts its calibration expectation in clause 9.1.1: where monitoring and measuring equipment evaluates OH&S performance, it is calibrated or verified as applicable, used and maintained as appropriate, and documented information is retained as evidence, covering both the measurement results and the calibration of the equipment itself. For an EHS team that means the gas detectors, dosimeters, sampling pumps, and torque tools behind exposure decisions need known status and a record trail. The standard names no software, so the question is what keeps that file current without a spreadsheet someone has to remember.

Axiospec gives each instrument an interval and a live status: in tolerance, due, overdue, or quarantined. Calibrations are logged with who, when, the readings, and the reference standard, written to a tamper-evident ledger, with an e-signature when you require one, and exportable as an audit pack per instrument. A Due Calendar shows what is due and overdue across sites and sends reminders before each date. Field technicians log from the native iOS and Android apps, offline if the site has no signal, with QR-code scanning to pull up the right instrument.

When an auditor asks how you know a detector reading was valid, the answer is its calibration record and status at the time of the reading. The live demo shows that flow with no signup, and the free plan runs a full program up to 50 active assets with unlimited users, which fits many EHS equipment files outright. Axiospec keeps the evidence clause 9.1.1 expects; it does not certify or guarantee conformance, which your certification body decides.
