6. Opportunity Hospitals offer an opportunity for sales in a wide range of products • Medical Air Systems • Medical Vacuum Systems • Waste Anesthetic Gas (WAG) Systems • Plant/Instrument Air and Laundry Air Systems

7. Gas System Risk Levels and Requirements • 3.3.90 Level 1 Medical Piped Gas and Vacuum Systems. Systems serving occupancies where interruption of the piped medical gas and vacuum system would place patients in imminent danger of morbidity or mortality. • 3.3.91 Level 1 Vacuum System. A system consisting of central-vacuum-producing equipment with pressure and operating controls, shutoff valves, alarm warning system, gauges, and a network of piping extending to and terminating with suitable station inlets at locations where patient suction could be required. • 3.3.92 Level 2 Medical Piped Gas and Vacuum Systems. Systems serving occupancies where interruption of the piped medical gas and vacuum system would place patientsat manageable risk of morbidity or mortality.

8. Gas System Risk Levels and Requirements (Continued) • 3.3.93 Level 3 Compressed Air System. A system of component parts, including, but not limited to, air compressor, motor, receiver, controls, filters, dryers, valves, and piping, that delivers compressed air <1100 kPa (<160 psi gauge) to power devices (hand pieces, syringe, cleaning devices, etc.) as a power source. • 3.3.94 Level 3 Piped Gas Systems. Systems serving occupancies where interruption of the piped medical gas would terminate procedures but would not place patients at risk of morbidity or mortality. • 3.3.95 Level 3 Piped Vacuum System. A Level 3 vacuum distribution system that can be either a wet system designed to remove liquids, air-gas, or solids from the treated area; or a dry system designed to trap liquid and solids before the service inlet and to accommodate air-gas only through the service inlet.
