Articles: What Medical Gas Testing Is Required?
Medical gas systems are used in healthcare facilities around the world. The system must meet stringent requirements to ensure a safe environment for both patients and practitioners and to provide immediate and precise care. From oxygen flow to outlets, the system is tested to ensure proper design and function. The testing can be done annually or based on hospital maintenance schedules. Medical gas testing and certification must comply with governing body standards. These bodies include The Joint Commission, NFPA, ASSE, and CGA. The medical gas verifier will inspect the system and its components, which may include:
- Outlets
- Alarms
- Vacuum Pumps
- Air Compressors
- Manifolds
- Zone Valve Boxes
- Emergency Oxygen Fill Stations
- Bulk Site
When medical gas certification is performed on new construction there are pre-certification tests that should be performed by the installation team, including performing standing pressure tests on newly installed piping. NFPA 99 outlines the testing to be performed by the installing contractor. Once those tests have been successfully completed, then the facility is ready for an independent medical gas verifier to review the system for compliance with NFPA 99.
The medical gas verifier will review the system and prepare a report outlining any deficiencies, and may make recommendations for correcting the system. A complete report should include model numbers, serial numbers, locations, and code references to help the facility representative understand the precise deficiency. The verifier may make recommendations for correction, but it is up to the facility to determine priority and set the repair schedule. Authorities having jurisdiction, such as The Joint Commission or the local fire marshal, will review the medical gas certification report when doing their own inspections and evaluations to be sure that the facility is taking adequate and timely steps to correct any problems.
