,Q1 DEMONSTRATE MASTERY OF CORE CONCEPTS
During a Level 1 installation of a medical gas pipeline, a contractor plans to use a
brazing filler metal with a melting point of 1,000°F. The system is intended for
oxygen service. Which of the following is the most critical requirement that must
be met?
A. The filler metal must be flux-coated to ensure a complete seal
B. The filler metal must be cleaned for oxygen service and meet the requirements of ASTM B
280 CORRECT
C. The brazing must be performed with a reducing flame to prevent oxidation
D. The filler metal must have a melting point above 1,100°F to prevent degradation in oxygen
RATIONALE: For medical gas systems, especially oxygen, the filler metal must be cleaned for
oxygen service and meet the requirements of ASTM B 280. Flux-coated filler metals are
prohibited because flux can contaminate the system. The melting point is not the primary
concern; the cleaning and standard compliance are critical. A reducing flame is not the specific
requirement for filler metal selection.
Q2 DEMONSTRATE MASTERY OF CORE CONCEPTS
A medical gas pipeline is being pressure-tested in accordance with NFPA 99. The
test pressure is set at 1.5 times the system operating pressure, but the system's
relief valves are set to relieve at a lower pressure. What is the correct course of
action?
A. Isolate or remove the relief valves to prevent damage during the test CORRECT
B. Increase the relief valve set points to match the test pressure
C. Proceed with the test, as relief valves are designed to handle overpressure
D. Reduce the test pressure to match the relief valve setting
RATIONALE: Relief valves are not designed to withstand the high test pressures and must be
isolated or removed to prevent damage and ensure accurate testing. Increasing set points would
compromise safety, and proceeding could damage the valves. Reducing test pressure would not
meet the required test pressure as per NFPA 99.

, Q3 DEMONSTRATE MASTERY OF CORE CONCEPTS
Which of the following best describes the primary purpose of the 'alarm' system in
a medical gas pipeline?
A. To provide a visual indication of system pressure at all times
B. To alert staff to a drop in pressure or other abnormal conditions in the system CORRECT
C. To automatically switch to a backup supply when the primary supply is depleted
D. To monitor the purity of the medical gas being delivered
RATIONALE: The alarm system is designed to alert personnel to any abnormal conditions, such
as pressure drops, which could indicate a leak or supply failure. It does not automatically switch
supplies (that is the source valve's function), nor does it monitor purity. Visual indication is a
function of pressure gauges, not alarms.
Q4 DEMONSTRATE MASTERY OF CORE CONCEPTS
What is the minimum distance required between a medical gas outlet and a
potential source of ignition, such as an electrical outlet, in a patient care room?
A. 6 inches
B. 12 inches
C. 18 inches CORRECT
D. 24 inches
RATIONALE: NFPA 99 requires a minimum separation of 18 inches between medical gas outlets
and electrical outlets or other ignition sources to reduce the risk of fire. This distance is based on
safety considerations for oxygen-enriched atmospheres. The other distances do not meet the
code requirement.
