Emergency Procedures Flashcards

A construction crew accidentally severs a medical gas branch line serving the emergency department. What is the RMGA's immediate priority?

Answer: Close the nearest upstream zone valve and implement the emergency plan for alternate gas supply

Closing the upstream zone valve stops the uncontrolled gas release and triggers implementation of alternate supply protocols for the affected area.

During a power outage, the medical gas alarm system loses power. According to NFPA 99, what provision must exist for alarm continuity?

Answer: Medical gas alarms must be connected to emergency power per NFPA 99 requirements

NFPA 99 requires medical gas alarm systems to be connected to the facility's emergency electrical system to maintain continuous monitoring.

When responding to a report of a hissing sound near a nitrous oxide manifold room, what personal protective equipment (PPE) should the RMGA use before entering?

Answer: Self-contained breathing apparatus (SCBA) if high concentration is suspected, plus gas monitor

High concentrations of nitrous oxide can cause asphyxiation by displacing oxygen, so gas monitoring and SCBA may be required before entering a potentially high-concentration area.

An RMGA finds that the oxygen concentration in a medical gas equipment room is reading 23.5% on the O2 monitor. What action is required?

Answer: Immediately ventilate the room, identify the oxygen source, and prohibit ignition sources

Oxygen levels above 23.5% create an enriched-oxygen fire hazard; immediate ventilation and ignition source control are required per NFPA 99 and facility protocols.

A cylinder manifold system automatically switches from the primary bank to the reserve bank. What emergency action should the RMGA take?

Answer: Notify the gas supplier to replenish the primary bank and document the switchover

Automatic switchover indicates the primary bank is depleted; notifying the supplier promptly ensures resupply before the reserve bank is exhausted.

Which of the following is a required element of a post-emergency report for a medical gas system incident under RMGA best practices?

Answer: Documentation of the timeline, affected areas, actions taken, and corrective measures

Best practices and regulatory requirements call for a written incident report capturing timeline, scope, response actions, and corrective steps to prevent recurrence.

If the medical gas master alarm panel shows a 'Source Alarm — Nitrogen Pressure Low' signal, which patient care activity is most immediately at risk?

Answer: Pneumatic surgical instruments and nitrogen-powered equipment

Nitrogen is primarily used to power pneumatic surgical tools; low nitrogen pressure directly threatens surgical procedures relying on nitrogen-driven instruments.
