RMGA Emergency Procedures 5

Question 1

An oxygen-enriched environment is detected in a patient room due to an undetected leak. Which fire hazard precaution is MOST critical?

Accepted Answer

Remove all ignition sources including electrical equipment and prohibit smoking

Answer

Oxygen-enriched atmospheres dramatically accelerate fire ignition and spread; removing all ignition sources is the most critical immediate precaution.

Question 2

During a mass casualty incident, the medical air system is insufficient to support the surge in ventilator demand. Which backup strategy is NFPA 99-compliant?

Accepted Answer

Deploy NFPA 99-compliant reserve cylinders of medical air and notify all clinical staff

Answer

NFPA 99 permits reserve cylinder supply as an emergency backup; only medical-grade compressed air may be used for patients, and staff must be notified of the supply change.

Question 3

A source alarm for 'Medical Vacuum Low' appears during a shift change. The on-coming RMGA finds one of two vacuum pumps is offline. What is the correct escalation path?

Accepted Answer

Immediately attempt to restore the offline pump and notify clinical leadership of the reduced redundancy

Answer

Restoring the offline pump restores full redundancy, and notifying clinical leadership ensures preparedness if vacuum levels drop further during repair.

Question 4

A medical gas area alarm activates showing 'Oxygen Low Pressure' for the NICU. The RMGA verifies the zone valve is open and the source pressure is adequate. What is the most likely cause?

Accepted Answer

Excessive demand in the NICU is exceeding line capacity or a pressure regulator has failed closed

Answer

When source pressure is adequate and the valve is open, low zone pressure indicates either demand exceeding line capacity or a failed-closed downstream pressure regulator.

Question 5

Following an emergency repair of a medical gas pipeline, which test must be completed per NFPA 99 before the system is returned to service?

Accepted Answer

Cross-connection testing, purity testing, and pressure testing per NFPA 99 Section 5.1

Answer

NFPA 99 mandates cross-connection, purity, and pressure verification tests after any pipeline repair to ensure patient safety before restoration.
