Short answer
A gas detector bump test and calibration log records a bump test before each use, confirming each sensor responds to gas and the alarms activate, and each full calibration with as-found and as-left readings. Gas testers and site safety staff keep it. Testing and calibration intervals come from the detector manufacturer and vary by model; AS/NZS 60079.29.2:2016 covers selecting, using and maintaining flammable gas and oxygen detectors.

Key takeaways
- The MapTrack gas detector bump test / calibration log has 9 columns and room for 20 entries. Columns: Date, Time, Tested By, O2 %, LEL %, CO ppm, H2S ppm, Other / Reading, Pass / Fail.
- Bump test before each use, usually daily. A power-on self-test does not expose the sensors to gas, so it does not replace a bump test.
- Calibrate at the manufacturer's interval, which varies by model and conditions, and again after a failed bump test or as the manufacturer directs.
- Record as-found and as-left readings for each sensor, plus the calibration gas concentration and batch number, so sensor drift shows up over time.
- Part 4.3 of the model WHS Regulations covers atmosphere controls for confined space entry; keep the detector log with the entry permit records.
- A detector that fails its bump test stays out of use until it is calibrated or repaired and passes again.

What is a gas detector bump test / calibration log?
A gas detector calibration log is a two-part record used to manage gas detection equipment in hazardous work environments. The first part is a daily bump test log, which is a register completed before each use to confirm that each sensor responds to its target gas and that alarms activate correctly. A bump test does not adjust the instrument; it simply verifies sensor response and alarm function. The second part is a full calibration record, completed periodically, that adjusts the instrument's readings against a certified reference gas concentration and documents the traceable calibration event with as-found and as-left readings for each sensor.
In Australia, gas detectors used in confined spaces, underground operations, oil and gas facilities and other hazardous environments are subject to WHS Regulations 2011, including Chapter 4, Part 4.3 covering confined spaces, and the relevant Australian Standards. AS/NZS 60079.29.2 specifies the requirements for selection, installation, use and maintenance of gas detectors in explosive atmospheres, while AS 2290 covers mine gas detection. The Safe Work Australia Code of Practice for Managing Risks of Hazardous Chemicals in the Workplace reinforces that atmospheric monitoring equipment must be maintained and calibrated to ensure reliable performance. Documented bump testing and calibration records demonstrate due diligence and may be required by principal contractors, safety regulators, auditors and insurance providers. For facilities operating under AS ISO/IEC 17025 accreditation, calibration of gas detection instruments must be performed by a competent person using traceable reference gases with documented certificates. Without these records, an organisation cannot prove that its gas detection equipment was properly maintained at the time of a gas exposure incident, which can have serious legal and safety consequences.

Benefits of using this gas detector bump test / calibration log
- Life safety assurance: documented bump tests and calibrations confirm that sensors will detect hazardous gases and trigger alarms in time to protect workers.
- Regulatory compliance: WHS legislation requires control measures, such as gas detectors, to be maintained so they remain effective. Records substantiate compliance.
- Detect sensor degradation early: a log of as-found readings over time reveals gradual sensor drift before it reaches a point of failure.
- Calibration gas traceability: recording calibration gas batch numbers and concentrations confirms that traceable gas was used, supporting audit requirements.
- Identify faulty instruments: repeated calibration failures or sensors that fail bump tests repeatedly indicate the instrument needs servicing or sensor replacement.
- Due diligence evidence: in the event of a gas detection incident, calibration records demonstrate the instrument was properly maintained.

What to include in a gas detector bump test / calibration log
This gas detector bump test / calibration log covers 6 key areas:
- Instrument details: make/model, serial number, asset/ID number, sensor types installed, last calibration date, next calibration due date.
- Daily bump test log (20 rows): date, time, tester name, O2 % reading, LEL % reading, CO ppm reading, H2S ppm reading, other sensor reading, overall pass/fail result.
- Full calibration record: for each sensor: target gas concentration, as-found reading, deviation, as-left reading, pass/fail and adjustment notes.
- Calibration gas details: gas mixture description, supplier, batch/lot number, concentration (%), cylinder ID and expiry date.
- Calibration event details: date calibrated, calibrated by, next calibration due, calibration method used.
- Technician sign-off: declaration and signature confirming the calibration has been performed correctly and the instrument is fit for service.
How to use this gas detector bump test / calibration log
- Fill in the instrument details at the top of the form (make/model, serial number, sensors installed, next calibration due).: Cross-reference the gas detector against your asset register to confirm the correct serial number, sensor configuration and current calibration status. Note the sensors installed (O2, LEL, CO, H2S, or others).
- Daily bump test:: Switch on the detector and allow it to complete its self-test. Apply test gas to each sensor using the appropriate bump test kit. Record the date, time, tester name and the sensor readings displayed. Mark Pass if all sensors respond above their alarm thresholds; mark Fail if any sensor does not alarm. Remove the instrument from service if it fails a bump test.
- Full calibration (periodic):: Connect the instrument to the calibration kit. Apply zero gas (clean air or nitrogen) to zero the sensors. Apply calibration gas at the target concentration and adjust the instrument to match. Record the as-found reading (before adjustment) and as-left reading (after adjustment) for each sensor. Note the deviation and pass/fail. Record calibration gas batch details.
- Record the next calibration due date and the technician's sign-off.: Calculate the next calibration due date based on the manufacturer recommendation, site safety plan and applicable standards. The technician must sign the record confirming the calibration was performed correctly.
- Attach a calibration sticker or tag to the instrument showing the next due date.: Apply a clearly visible calibration label or tag to the instrument body showing the calibration date, next due date and technician initials. This allows operators to verify calibration status before each use.
In MapTrack, you can automate compliance tracking and audit trails. Each submission is stored as a timestamped PDF against the asset record.

Gas detectors should be bump tested before each use, which in most site environments means daily. A bump test takes less than a minute and verifies that each sensor and alarm is operational. Do not rely solely on the instrument's self-test (power-on check) as a substitute for a bump test; self-tests do not expose the sensor to gas.
Full calibration should be performed at the interval specified by the manufacturer, typically every 3 to 6 months, or earlier if the instrument fails a bump test, a sensor is replaced, the instrument has been exposed to very high gas concentrations, it has been stored for an extended period, or it has been subjected to significant impact. Always follow the most stringent requirement from the manufacturer, your site safety plan and applicable Australian Standards.
