Cylinder Changing Procedures
WARNING: High pressure oxygen systems must be handled with CAUTION. Spontaneous combustion
may occur if oxygen comes into contact with grease or oil. Ensure that hands, gloves, clothing and tools
are kept clean and free of oil and grease. Be careful not to introduce dust or other contaminants into the
system when changing cylinders. Failure to comply with the procedure may be hazardous.
WARNING: Fire Hazard. DO NOT permit smoking, or any other source of ignition in area where the
manifold is located, or near the relief valve vent outlet. Be certain that all connections are free of dirt,
grease, and oil. These substances burn with great intensity in air enriched with oxygen, or nitrous
oxide and some gas mixtures.

1. Keep the main bank valve open throughout these procedures.
2. Close cylinder valves on all empty cylinders.
3. Disconnect pigtails from cylinder valve outlets, using an appropriate wrench.
4. Place protective caps over the cylinder valves of the empty cylinders and move them aside.
5. Remove protective caps of the full cylinders. Visually inspect the cylinder valves for dust, grease or oil.
6. Using a clean (lint free) cloth, wipe each cylinder valve outlet clean. Do not use your fingers.
7. Standing to one side, “crack” the cylinder valve by briefly opening and closing them to blow out any dust. Make
sure they are pointing away from you and other personnel.
8. Connect the pigtails to the cylinder valve outlets and tighten the nut with an appropriate wrench.
9. Very S-L-O-W-L-Y open the cylinder valve on the cylinder closest to the control cabinet. Watch the bank pressure
display on the front of the cabinet to make sure the pressure rises “S-L-O-W-L-Y” to the full cylinder pressure
reading. Wait one full minute.
10. Proceed to S-L-O-W-L-Y open the remaining cylinder valves one at a time.
