How often should ICRA monitoring be done during healthcare construction?

Q: How often should ICRA monitoring be done during healthcare construction?

Daily at minimum for Class III and above — barrier integrity, pressure readings, housekeeping, documented. Class IV/V adds continuous manometer monitoring with data logging and alarms. Class I/II verified on task completion. Excursions trigger immediate corrective action.

Q: How often must ICRA barriers be inspected?

Daily during active construction for Class III+, continuous pressure logging for Class IV/V.

Q: Must monitoring be documented?

Yes — daily logs of readings and inspections.

Facilities engineer on daily ICRA monitoring rounds inspecting a containment barrier and pressure gauge — Daily walkthroughs for Class III and above — continuous pressure logging for Class IV/V.

ICRA monitoring is daily at minimum during active construction for Class III and above: barrier integrity, pressure differential readings, and housekeeping checked every workday and documented. Class IV/V projects add continuous manometer monitoring with data logging and alarming. Lower classes (I/II) are verified on completion of the task. The frequency scales with the class — and any excursion (lost pressure, breached barrier) triggers immediate corrective action, not a note for tomorrow.

Monitoring by class

Class I/II: verify controls on task completion — ceiling tiles replaced, area cleaned, dust contained.
Class III: daily walkthrough — barriers intact and sealed, negative pressure holding, dust mats serviceable, waste contained, adjacent areas clean.
Class IV/V: daily documented inspections plus continuous differential-pressure monitoring with logging and alarms; anteroom discipline observed.

What gets checked

Barrier seals (top, bottom, penetrations), manometer readings against the facility’s pressure target (-0.01″ w.c. is a common practice, not an ICRA 2.0 or CDC requirement), NAM operation and exhaust routing, door discipline (no propping), dust migration into adjacent occupied areas, sticky mat condition, and waste container handling. Adjacent patient areas get a visual check for tracked dust — the earliest warning sign of containment failure.

Documentation

Log readings and inspection results daily; record excursions with the corrective action taken and re-verification. This log is what surveyors and the infection preventionist review — a monitoring program with no written record is indistinguishable from no monitoring program.

Daily eyes, continuous gauges, written everything.

FAQ

How often must ICRA barriers be inspected?
Daily during active construction for Class III and above, with continuous pressure logging for Class IV/V.

What happens when monitoring finds a problem?
Immediate corrective action — restore pressure, reseal the barrier — documented with re-verification. Excursions aren’t carried to the next day.

Must monitoring be documented?
Yes. Daily logs of readings and inspections are the evidence surveyors expect.
