What color is the standard pipeline and cylinder coding for medical oxygen in the United States?
Answer: Green
In the US, medical oxygen is color-coded green per CGA standards.
What is the purpose of a zone valve in a medical gas pipeline system?
Answer: To allow isolation of gas supply to a specific area for maintenance or emergencies without affecting the entire facility
Zone valves allow specific sections to be shut off without interrupting supply to the rest of the facility.
What safety system prevents connecting a medical gas cylinder to the wrong yoke or regulator?
Answer: Pin Index Safety System (PISS)
PISS uses specific pin positions on the cylinder valve that correspond to holes on the yoke, mechanically preventing wrong gas connection.
What does a medical gas alarm panel monitor and how should alarms be responded to?
Answer: Pipeline pressure, reserve supply status, and system conditions, requiring immediate investigation
Medical gas alarm panels monitor pipeline pressures, reserve supply status, and operating conditions.
What is the standard operating pressure for medical gas pipeline systems (oxygen, air, nitrous oxide) in a US hospital?
Answer: 50 psi
Standard medical gas pipeline operating pressure is 50 psi per NFPA 99.
Why must oil and grease be kept away from oxygen equipment and fittings?
Answer: Oxygen is a powerful oxidizer and can cause spontaneous ignition of hydrocarbons under pressure
Oxygen drastically lowers the ignition temperature of hydrocarbons, which can spontaneously ignite under high-pressure oxygen.
