What a gas detector inspection workflow is
A gas detector inspection workflow is the chain of documents an employer uses to keep portable gas detection reliable — the instruments people rely on before and during confined-space or atmosphere-sensitive work. It links the risk assessment, the detector register, the pre-use bump test, the periodic calibration and the defect or out-of-service action.
This page is an educational overview of how those documents typically connect. It does not set bump-test or calibration intervals — the employer is responsible for ensuring detectors are reliable and used correctly, under the applicable law and the maker’s guidance.
Why these documents connect
A gas detector gives a reading that people make life-or-death decisions on, so the documents make sure it is working before use and accurate over time. The risk assessment decides where detection is needed; the register tracks each instrument; the bump test confirms it responds before use; and periodic calibration confirms accuracy. A failed bump test or calibration takes it out of service.
Connecting the documents means a detector that does not respond is caught before it is taken into a confined space, and a drifting instrument is recalibrated rather than trusted blindly.
The typical sequence
- Required before: a risk assessment and a detector register define where detection is needed and what is used.
- Used with: a pre-use bump test confirms the detector responds before each use.
- Completed after: periodic calibration confirms accuracy, recorded against the instrument.
- Escalation: a failed bump test or calibration removes the detector from service.
- These are example steps only — adapt the sequence to your detectors and the applicable law.
When the chain runs
The chain runs before each use through the bump test, and on the periodic calibration cycle for the instrument.
It also runs after the detector is dropped, alarms unexpectedly, or returns from repair.
Who owns each step
- The employer owns the detection regime and the instruments.
- The user carries out the pre-use bump test.
- A competent person carries out periodic calibration.
- A supervisor removes failed detectors from service.
Common mistakes
- Taking a detector into use without a bump test.
- Relying on calibration alone and skipping the bump test.
- Using a detector past its calibration date.
- No register, so instruments are missed.
- Ignoring an alarm or a failed response.
Records & retention (high level)
Employers generally keep the detector register, bump-test and calibration records for as long as the instruments are in use and for a period afterwards, in line with their obligations and data-protection duties.
This page does not state a required period or interval — confirm both with the applicable law and the maker’s guidance.
Sharing the workflow as a PDF
Detector registers, bump-test logs and calibration records are commonly stored as PDFs so each instrument’s history stays together and can be shared or audited. Exporting to PDF supports the record; it does not make the inspection official or guarantee compliance.
Employer notes
- Require a bump test before each use, not just calibration.
- Track each detector on a register with its calibration history.
- Remove failed or overdue detectors from service.
- Follow the maker’s guidance on bump-test and calibration intervals.
Worker notes
- Bump test the detector before taking it into use.
- Do not enter on a detector that is out of calibration.
- Act on an alarm immediately — leave and report.
- Hand in detectors for calibration when due.
Country considerations
Gas detection practice, confined-space duties and the official authority vary by country. This page is high-level and general — it is not a statement of any country’s law and not a guarantee that a process or form is valid anywhere.
Always confirm the current requirements with the official authority for your country and a qualified professional.
Who is responsible
The employer is responsible for ensuring gas detection is reliable, calibrated and used correctly, and for compliance. This page is an educational overview with a template example; it does not set intervals, does not make a workplace compliant and does not transfer responsibility.
