Each dedicated gas system shall be tested with oil-free, dry nihogen, to veri$ that there are no cross-connections to any other system. To determine the presence of cross-connections is to pressurize only one system to 50 psig at a time, and then test each outlet to veri$ that the gas exists only at each of the expected outlets. 2. The testing of the nominal 55 psig medical gas systems (I.E. oxygen, nitrous oxide, and medical air), should be done in a sequence as to allow the least chance of hazard if a cross connection did occur. This would typically require testing the medical air system firsl the oxygen system next and the nihous oxide last. Each gas piping system shall be purged of contaminants by flushing with the appropriate source gas while under system pressure. The piping system for each gas shall be purged by successively opening each outlet in progressive order, starting with the outlet that is nearest the pressure source and ending at the outlet that is farthest from the pressure source. The gas shall be purged through a white cloth material at a flow rate of at least 100 liters per minute until there is no longer any evidence of discoloration or particulate. It is also important to purge for a sufficiently long time so that all of the test gas previously used has been removed from the system.

Install exposed raceways parallel or at right angles to nearby surfaces or structural members and follow surface contours as much as possible. l. Run parallel or banked raceways together on common supports. 2. Make parallel bends in parallel or banked runs. Use factory elbows only where elbows can be installed parallel; otherwise, provide field bends for parallel raceways. Join raceways with fittings designed and approved for that purpose and make joints tight. l. Use insulating bushings to protect conductors. 2. For Nonmetallic Conduit (PVC): Wipe conduit clean and dry before joining. Apply full, even coat of cement to entire area that will be inserted into fitting. Let joint cure for 20 minutes minimum. Lay out work in advance to avoid excessive concentrations of multiple conduit runs. Locate conduits so that the strength of structural members is unaffected and the conduits do not conflict with the services ofthe other trades.
