Gas detection system maintenance checklists for the quarterly and annual rounds: 2 free lists, 8 items and 12 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against IMC (mechanical code); the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Gas detection system quarterly maintenance checklistquarterly
- Every quarter, because a sensor in a parking area or kitchen sits in dust, grease and moisture and drifts long before anyone smells the problem. Run by: The controls or mechanical tech on the quarterly round; the field observes and documents, calibration stays with the certified tech.
- Gas detection system annual maintenance checklistannual
- Once a year, timed with the calibration visit so the whole detection-to-ventilation chain is proven end to end while the tech is on site. Run by: The controls service lead inspects and documents; the licensed tech performs and certifies the bump test and calibration.
What most often fails on a gas detection system
- Panel showing a fault or a sensor past its calibration-due date that everyone had learned to ignore.
- A refrigerant or CO head painted over, wrapped, or mounted where a later remodel walled it off.
- The gas alarm no longer starts the exhaust fan or drops the makeup-air damper, so detection happens but nothing ventilates.
- Sensors bump-tested but the interlocked exhaust and damper response never re-verified after a controls change.
- Sensor count on the panel no longer matches the field after a remodel added parking or kitchen area with no coverage.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which gas detection system maintenance rounds do these checklists cover?
- Gas detection system quarterly maintenance checklist (quarterly): Every quarter, because a sensor in a parking area or kitchen sits in dust, grease and moisture and drifts long before anyone smells the problem. Gas detection system annual maintenance checklist (annual): Once a year, timed with the calibration visit so the whole detection-to-ventilation chain is proven end to end while the tech is on site.
- Who runs the gas detection system maintenance round?
- The controls or mechanical tech on the quarterly round; the field observes and documents, calibration stays with the certified tech. The controls service lead inspects and documents; the licensed tech performs and certifies the bump test and calibration.

- Which standards is gas detection system work verified against?
- IMC (mechanical code), published by the International Code Council. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (8 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
