RMGA System Testing 4

Question 1

What type of gas must NOT be used to perform a pressure leak test on an oxidizer (oxygen or nitrous oxide) medical gas pipeline?

Accepted Answer

Compressed oxygen

Answer

Oxygen itself must not be used for pressure testing because high-pressure oxygen in contact with system contaminants or lubricants creates a serious fire and explosion hazard.

Question 2

An RMGA notices that a medical gas outlet station label reads 'O₂' but the outlet body is color-coded green and has a DISS connector for oxygen. What additional verification should be performed?

Accepted Answer

Cross-connection test and gas purity analysis at that outlet

Answer

Visual labeling and physical connector verification alone are insufficient; a cross-connection test and gas analysis must confirm the correct gas is actually being supplied to that outlet.

Question 3

During medical gas system testing, which of the following alarm conditions must be tested and verified to function correctly?

Accepted Answer

Both master alarm panels and area alarm panels

Answer

NFPA 99 requires that both master alarm panels (at the source) and area alarm panels (at each zone) be tested and verified to annunciate correctly during system testing.

Question 4

What is the significance of the 'blow-down' test performed on WAGD (Waste Anesthetic Gas Disposal) systems?

Accepted Answer

It verifies the system can achieve adequate flow and negative pressure to capture waste anesthetic gas

Answer

The blow-down test confirms that the WAGD system can generate sufficient negative pressure and flow to effectively capture and remove waste anesthetic gases from operating room equipment.

Question 5

According to NFPA 99, after a repair is made to a medical gas pipeline, which tests must be repeated before returning the system to service?

Accepted Answer

Leak test and cross-connection test for the affected section

Answer

After any repair, NFPA 99 requires at minimum a pressure leak test and a cross-connection test on the affected portion of the system before returning it to service.
