RMGA Safety Protocols & Risk Management 5 — Questions and Answers
Question 1: When a master alarm panel indicates a 'High Pressure' warning for the oxygen system, the gas administrator should first:
- Immediately shut down the entire oxygen system
- Verify the reading at the source equipment and check for regulator malfunction (Correct answer)
- Notify all clinical staff to prepare for an oxygen outage
- Increase the set point on the main pressure regulator
Correct answer: Verify the reading at the source equipment and check for regulator malfunction
Verifying the alarm at the source distinguishes a true high-pressure event from a faulty sensor or gauge before taking potentially disruptive action.
Question 2: NFPA 99 requires that medical gas area alarm panels be located:
- Inside the mechanical room nearest to the source
- Where they can be continuously observed by authorized personnel (Correct answer)
- Adjacent to each zone valve box they monitor
- Only in areas where flammable gases are used
Correct answer: Where they can be continuously observed by authorized personnel
Area alarm panels must be located where they will be noticed by staff at all times, such as nurses' stations, to ensure prompt response.
Question 3: The purpose of an Interim Life Safety Measure (ILSM) during medical gas system construction is to:
- Reduce the facility's insurance premiums during renovation
- Compensate for reduced life-safety system functionality and protect patients during the work period (Correct answer)
- Accelerate the construction timeline
- Document contractor qualifications for accreditation records
Correct answer: Compensate for reduced life-safety system functionality and protect patients during the work period
ILSMs are temporary measures (additional patrols, fire watches, alternate egress) that maintain patient safety when normal life-safety features are impaired.
Question 4: A medical gas system 'near-miss' event should be reported and analyzed because:
- Regulatory agencies require reporting of all minor incidents
- Near-misses reveal latent system weaknesses before a serious patient harm event occurs (Correct answer)
- Only insured facilities are required to investigate near-misses
- Near-misses always indicate intentional misuse of the system
Correct answer: Near-misses reveal latent system weaknesses before a serious patient harm event occurs
Near-miss analysis identifies hazard precursors, allowing corrective action before a similar event results in patient injury.
Question 5: Manifold systems for medical gas cylinders must have check valves to:
- Regulate outlet pressure to the distribution system
- Prevent backflow from the pipeline into individual cylinders (Correct answer)
- Filter particulates from the gas supply
- Automatically switch between primary and secondary banks
Correct answer: Prevent backflow from the pipeline into individual cylinders
Check valves prevent higher-pressure pipeline gas from flowing back into cylinders, avoiding contamination and cylinder over-pressurization.
Question 6: Which risk assessment tool uses a numerical matrix to prioritize hazards by multiplying the likelihood of occurrence by the severity of consequences?
- Fishbone (Ishikawa) Diagram
- Risk Priority Number (RPN) / Risk Matrix (Correct answer)
- Process Flow Map
- Fault Tree Analysis
Correct answer: Risk Priority Number (RPN) / Risk Matrix
A Risk Matrix or RPN calculation ranks hazards by combining probability and severity scores, helping teams focus on the highest-priority risks.
Question 7: Under NFPA 99, the maximum allowable storage quantity of oxidizing medical gases (e.g., oxygen) inside a healthcare occupancy without additional safeguards is:
- 300 cubic feet
- 3,000 cubic feet (Correct answer)
- 1,000 cubic feet
- 500 cubic feet
Correct answer: 3,000 cubic feet
NFPA 99 and NFPA 55 permit up to 3,000 cubic feet of oxidizing gas in a healthcare occupancy storage room meeting specific construction requirements before stricter controls apply.
