RMGA Emergency Procedures 4

Question 1

A fire occurs in the medical gas storage room. Which action should the RMGA take regarding cylinder valves?

Accepted Answer

Evacuate the area and allow the fire department to manage the cylinders

Answer

Cylinders in a fire are a job for the fire department; the RMGA should evacuate personnel and ensure the fire department is informed of the hazardous materials present.

Question 2

During an emergency shutdown drill, the RMGA closes a zone valve serving the operating rooms. How should clinical staff be notified before this action in a real emergency?

Accepted Answer

Notification must be given to all affected clinical staff prior to interrupting supply

Answer

NFPA 99 and JCAHO standards require notifying all affected clinical areas before any planned interruption to medical gas supply.

Question 3

The RMGA discovers that a medical gas outlet in an OR has been cross-connected, supplying nitrogen instead of oxygen. What is the immediate action?

Accepted Answer

Immediately shut down the affected outlet, notify clinical staff, and initiate a full verification before restoring service

Answer

A cross-connection is a life-threatening error requiring immediate shutdown, clinical notification, and complete system verification before the outlet is returned to service.

Question 4

A liquid oxygen bulk system experiences a pressure relief valve lift during unusually high demand. What does this event signify?

Accepted Answer

System pressure exceeded the relief valve set point, requiring investigation of demand or regulator function

Answer

A relief valve lift indicates pressure exceeded the set point, which may signal excessive demand, a malfunctioning vaporizer, or a regulator issue that must be investigated.

Question 5

When a medical gas pipeline is contaminated with particulate matter after a construction repair, what must occur before returning the line to service?

Accepted Answer

The line must be purged, tested for purity, and verified per NFPA 99 before clinical use
