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.
- True
- False
- True
Correct Answer
Explanation 1 / 3
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.
- True
- False
- True
Correct Answer
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?
- Oil-free, dry Argon MD
- Oil-free, dry Helium NF
- Oil-free, dry Nitrogen NF 2 / 3
- Any inert gas
- Oil-free, dry Nitrogen NF
Correct Answer
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.
- True
- False
- True
Correct Answer
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.
