RMGA System Testing 3

Question 1

An RMGA is verifying outlet flow rates during system testing. What is the minimum acceptable flow rate at a single oxygen outlet per NFPA 99 for a general care area?

Accepted Answer

5 L/min

Answer

NFPA 99 specifies a minimum flow rate of 5 L/min at each individual oxygen outlet under system operating conditions for general patient care areas.

Question 2

During cross-connection testing using an oxygen analyzer, what reading indicates a cross-connection exists between the oxygen and nitrous oxide lines?

Accepted Answer

Any non-zero reading at the nitrous oxide outlet when oxygen is isolated

Answer

Any detectable oxygen concentration at a nitrous oxide outlet when only nitrogen test gas is flowing through the nitrous oxide line indicates a cross-connection.

Question 3

Who is authorized to certify that a new medical gas piping system meets all NFPA 99 requirements before it is placed into service?

Accepted Answer

A qualified ASSE 6010 medical gas system verifier

Answer

NFPA 99 requires that a qualified, independent verifier credentialed to ASSE 6010 standard certify the system before it is placed into service.

Question 4

When testing a medical vacuum system, what minimum vacuum level must be achieved at each inlet station to pass?

Accepted Answer

-380 mmHg

Answer

NFPA 99 requires that medical vacuum systems maintain a minimum of -380 mmHg (approximately -7.3 psi) at each inlet under peak demand conditions.

Question 5

What is the purpose of testing the automatic switchover function of a medical gas source equipment during system testing?

Accepted Answer

To confirm the backup supply activates automatically when the primary supply is depleted

Answer

Switchover testing confirms that the reserve or secondary gas supply automatically activates and maintains system pressure when the primary supply is exhausted or fails.
