Question 1

Which NFPA standard governs clean agent fire extinguishing systems such as FM-200 and Novec 1230?

Accepted Answer

NFPA 2001

Answer

NFPA 2001 covers clean agent fire extinguishing systems, including halocarbon and inert gas agents used in total flooding applications.

Question 2

FM-200 (HFC-227ea) extinguishes fires primarily through which mechanism?

Accepted Answer

Heat absorption and chemical flame inhibition

Answer

FM-200 acts by absorbing heat from the flame and providing some chemical inhibition of the combustion chain reaction, unlike purely inert gas agents.

Question 3

For CO2 total flooding systems, high-pressure storage cylinders maintain the agent at approximately:

Accepted Answer

850 psi at room temperature

Answer

High-pressure CO2 systems store agent as a liquid at approximately 850 psi at ambient room temperature, while low-pressure systems store it at −20°F and 300 psi.

Question 4

Inergen (IG-541) is composed of which combination of gases?

Accepted Answer

Nitrogen, argon, and carbon dioxide

Answer

Inergen (IG-541) is a blend of 52% nitrogen, 40% argon, and 8% carbon dioxide; the CO2 component stimulates breathing to help occupants evacuate.

Question 5

Per NFPA 2001, the minimum hold time required after a clean agent total flooding system discharges is:

Accepted Answer

10 minutes

Answer

NFPA 2001 requires a minimum 10-minute agent hold time following discharge to ensure fire knockdown and prevent reflash before manual intervention.
