RMGA Safety Protocols & Risk Management 4 — Questions and Answers
Question 1: During a medical gas system shutdown drill, staff discover that the zone valve box in the ICU is not labeled. The correct action is to:
- Continue the drill and document the finding for a future project
- Stop the drill, label the box correctly before resuming, and document the corrective action (Correct answer)
- Call the original installer to re-label all valves
- Assume the valve serves the nearest room and proceed
Correct answer: Stop the drill, label the box correctly before resuming, and document the corrective action
Unlabeled zone valves are a life-safety deficiency; they must be corrected immediately because incorrect valve closure during an emergency can harm patients.
Question 2: The term 'oxygen enriched atmosphere' (OEA) is defined as an atmosphere containing oxygen above:
- 21%
- 23.5% (Correct answer)
- 25%
- 30%
Correct answer: 23.5%
An OEA is defined as any atmosphere with oxygen concentration above 23.5%, significantly increasing the flammability of materials.
Question 3: A cylinder restraint system is required in medical gas storage areas primarily to prevent:
- Unauthorized access to the cylinders
- Cylinders from falling and causing valve damage or projectile hazard (Correct answer)
- Condensation from forming on the cylinder surface
- Temperature fluctuations affecting gas pressure
Correct answer: Cylinders from falling and causing valve damage or projectile hazard
Unsecured high-pressure cylinders that fall can shear their valves, converting the cylinder into a dangerous projectile.
Question 4: A Permit-Required Confined Space for medical gas work would include a space that:
- Contains more than two gas outlets
- Has limited means of entry/exit and may contain a hazardous atmosphere (Correct answer)
- Requires a ladder to access the piping
- Is located below the first floor of a building
Correct answer: Has limited means of entry/exit and may contain a hazardous atmosphere
Permit-Required Confined Spaces are defined by OSHA as spaces with restricted entry/exit, potential for hazardous atmospheres, or engulfment hazards.
Question 5: When a healthcare facility receives a medical gas cylinder with a damaged valve, the correct action is to:
- Repair the valve in-house and place the cylinder in service
- Return the cylinder to the supplier and document the non-conformance (Correct answer)
- Wrap the valve with tape and use the cylinder cautiously
- Place the cylinder in service only for non-critical areas
Correct answer: Return the cylinder to the supplier and document the non-conformance
Damaged cylinders must be returned to the supplier; in-house repair of pressure vessel components is not permitted and creates a safety hazard.
Question 6: Under OSHA standards, a Safety Data Sheet (SDS) for a medical gas must be accessible to employees:
- Only during normal business hours at the administrative office
- At all times during each work shift where the gas is used or stored (Correct answer)
- Only when an incident has occurred involving that gas
- Upon written request to the safety officer
Correct answer: At all times during each work shift where the gas is used or stored
OSHA's Hazard Communication Standard (29 CFR 1910.1200) requires SDS to be immediately accessible to employees during their work shifts.
Question 7: The primary reason medical gas piping systems require pressure gauges at the source equipment AND at area alarm panels is:
- To satisfy insurance audit requirements
- To allow monitoring of system pressure at both supply and point-of-use for rapid anomaly detection (Correct answer)
- To measure gas consumption for billing purposes
- To comply with fire department inspection requirements
Correct answer: To allow monitoring of system pressure at both supply and point-of-use for rapid anomaly detection
Dual monitoring at source and use points allows staff to distinguish between supply failures and local distribution problems, enabling faster emergency response.
