Medical gas system quarterly maintenance checklist

Clinical staff and nursing leadership told before panel tests

Charge nurse for each area and clinical engineering told the round's timing and that lamp and audible tests will sound, before any test button is pressed, names logged.

No zone or source valve moved on the walk-down

Valves are read, never operated for convenience. A shutdown found needed goes to the facility's planned-interruption procedure with clinical sign-off first.

Oxygen, medical air and vacuum source status observed

Each source in normal operation, in-use and reserve banks reading as expected, no source in an alarm or changeover-locked state.

Manifold and cylinder area condition checked

Cylinders secured and segregated full from empty, manifold regulators steady, no hissing or frost at fittings, ventilation and signage intact.

Line pressure at each source read against the design

Main line gauge for oxygen, medical air and each other positive-pressure gas read and logged against the design operating pressure and last quarter's reading.

Medical air dew point and carbon monoxide monitors read

Monitor displays at the medical air source in their normal range with no alarm, readings logged against last quarter's. Facilities with no medical air plant note it.

Source equipment room kept free of combustibles

No cartons, rags, oil or unrelated stock in the source or manifold room, and no oil or grease on regulators, valves or cylinder connections.

Cylinder storage rooms away from the manifold checked where kept

Where cylinders are stored away from the manifold, each chained or racked upright, full kept apart from empty and marked, room sign posted, and none standing loose in a corridor or room.

Master and area alarm panels showing normal

Panels reading normal with no active or muted alarms, lamp/audible test exercised, gas and zone labels on each panel legible.

Alarm response contacts posted at each master panel

Call list posted at each master alarm panel naming who responds to each signal, and the staff watching that panel able to say who they would call.

Source, main and riser shutoffs labeled and reachable

Each shutoff tagged for its gas and what it isolates, secured in its normal position per facility practice, with nothing stored in the way.

Zone valve boxes labeled and accessible

Each valve box labeled for the gas and the area it serves, window intact, nothing stored in front of it, valve position as expected.

Station outlets condition checked, no leaks or odor

Outlets hold and release a probe without dragging, faceplates and gas-specific fittings intact, no hissing at the wall and no odor in the room.

Outlet and alarm complaints from clinical staff logged

Charge nurse on each area walked asked about dragging outlets, hissing or nuisance alarms, and a work order opened for each so nothing stays verbal.

Round closed with clinical staff and findings logged

Charge nurses told the round is done and panels are normal, and the rooms sampled, pressures and findings logged so next quarter samples other rooms.
