Station inlets for WAGD service shall be legibly marked to identify them and shall be of
a type appropriate for the flow and vacuum level required by the facility’s gas anesthetic
machines.
o True
o False
Correct Answer
A. True
Explanation
,The statement is true because station inlets for WAGD (Waste Anesthetic Gas Disposal)
service need to be clearly marked and should be suitable for the flow and vacuum level
needed by the gas anesthetic machines in the facility. This ensures that the correct gas
supply is used and helps maintain the safety and efficiency of the equipment.

Compressors for medical air shall be designed to prevent the introduction of
contaminants or liquid into the piping system.
o True
o False
Correct Answer
A. True
Explanation
Compressors for medical air need to be designed in a way that ensures contaminants or
liquid cannot enter the piping system. This is crucial because medical air is used in
various medical procedures and any contamination or presence of liquid could pose
serious health risks to patients. Therefore, it is important to have compressors
specifically designed to prevent the introduction of contaminants or liquid into the
medical air piping system.

While brazing medical-gas copper joints, a purge gas shall flow continuously to prevent
the formation of copper oxide on the inside surface of the joint. What shall be used as a
purge gas?
o Oil-free, dry Argon MD
o Oil-free, dry Helium NF
o Oil-free, dry Nitrogen NF
, o Any inert gas
Correct Answer
A. Oil-free, dry Nitrogen NF
Explanation
During the brazing process of medical-gas copper joints, it is important to prevent the
formation of copper oxide on the inside surface of the joint. To achieve this, a purge gas
needs to flow continuously. The most suitable option for a purge gas in this scenario is
oil-free, dry Nitrogen NF. Nitrogen is an inert gas that does not react with copper or
other materials, making it ideal for preventing oxidation. Additionally, using oil-free and
dry nitrogen ensures that no contaminants or moisture are introduced into the joint,
maintaining the integrity of the medical-gas system.

Where instrument air systems are provided with standby headers, in the event of a
compressor failure, the standby header shall automatically serve the system.
o True
o False
Correct Answer
A. True
Explanation
In instrument air systems that have standby headers, if a compressor fails, the standby
header will automatically take over and provide air to the system. This ensures that
there is no interruption in the supply of instrument air, even in the event of a compressor
failure. Therefore, the statement is true.
