Medical gas system annual maintenance checklist
The annual medical gas system service is the deep pass: the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against NFPA 99. Confirm the edition your authority having jurisdiction has adopted.
The checklist
Every item, and the photo evidence it needs
The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.
Notice and planned interruption
Clinical engineering, nursing and switchboard told before testing
Areas, times and expected alarms agreed with clinical engineering and nursing leadership, and staff at each master panel told signals are coming, before the verifier starts.
No photoPlanned-interruption sign-off on file before any zone is shut
A zone valve closes for testing only under the facility's planned-interruption procedure, with clinical sign-off and patients on portable supply or moved as clinical staff direct.
No photo
Verification observed
Verifier's certification and testing scope recorded
Verifier's name, firm and current certification noted before work starts, and the scope of this year's testing agreed with the facility in writing.
No photoVerifier's source and pressure checks observed and recorded
Watch the certified verifier work the source equipment and readings, record which gases were checked and the outcome the verifier reports.
Alarm actuation observed at each panel
Alarm points exercised during verification confirmed to annunciate and clear at the master and area panels, findings recorded.
Source changeover to reserve observed and reset
Changeover to reserve and the reserve-in-use signal watched at the master panel, then the source returned to its normal side and the panel back to normal.
Gas concentration and purity results recorded per gas
Verifier's concentration and purity readings at sampled outlets recorded for each gas, with any out-of-range outlet held from clinical use until corrected and retested.
No photo
Outlets and cross-connection
Outlet performance and gas-specific fit observed
Verifier's outlet checks observed across sampled rooms, gas-specific indexing confirmed so no outlet accepts the wrong fitting, results recorded.
Failed outlets listed by room and retested after repair
Each outlet that failed flow, latch or indexing listed by room, rebuilt or replaced under a planned interruption, and retested by the verifier before clinical use.
No photo
Return to clinical use
Every zone reopened and area panels normal before handback
Each zone valve closed for testing reopened and secured, and the area panel reading normal for every gas it serves, before the charge nurse is told the area is back.
Clinical staff and switchboard told the system is back
Charge nurses, clinical engineering and the staff at each master panel told testing is over and the system restored, with names and times logged.
No photo
Housekeeping and records
Source area and valve access kept clear
Required clearances at the source and manifold maintained, all zone valve boxes reachable, labeling still current after any changes.
Zone valve schedule updated from the zone test results
Rooms each zone valve was found to serve during testing compared with the facility's valve schedule and drawings, and both updated after renovations or renumbering.
No photoVerification report filed with the round record
Verifier's report received and attached to the maintenance record, any deficiencies noted with a follow-up owner.
What usually sends this back
The failures are almost always the evidence, not the work
- Verification results left on the verifier's paperwork and never copied into the facility record, so the next round starts blind.
- A source changeover or alarm point exercised during verification but the corrected setting never confirmed back at the master panel.

Common questions
6 answers
- What does this medical gas system annual checklist cover?
- 14 items across 5 sections, covering notice and planned interruption, verification observed, outlets and cross-connection, return to clinical use, and more. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- The facilities lead documenting the round while the certified medical gas verifier performs the annual verification.
- When in the schedule should this walk happen?
- Once a year, scheduled with the verifier so the site team can observe the verification and record what was found before areas go back into clinical use.
- Why do these items ask for a photo?
- 7 of the 14 items call for photo evidence, 9 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a medical gas system annual inspection?
- Verification results left on the verifier's paperwork and never copied into the facility record, so the next round starts blind. A source changeover or alarm point exercised during verification but the corrected setting never confirmed back at the master panel.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 9 required photos exist. Approved walks roll into a branded turnover package with a tamper evident record behind every line.
