into the agent being recovered and has a means of visually inspecting the recovered
agent for contaminants.: Dry Chemical Closed Recovery System 6. A system that
provides for the transfer of halogenated agents between fire extinguishers, supply
containers, and recharge and recovery containers so that none of the halogenated

10. Either a local alarm device to indicate when an extinguisher is removed from its
designated location or a method of electronic communication (data transmission)
between an in-place fire extinguisher and an electronic monitoring device/system.:
Electronic Monitoring
11. Extinguisher retention device designed to mount and secure a specific
extinguisher model onto various surfaces by incorporating releasable straps or bands
to secure the fire extinguisher.: Extinguisher Bracket
12. An identifiable and readily accessible fire extinguisher housing device designed
to store and protect fire equipment.: Extinguisher Cabinet
1/5
, .
13. Extinguisher mounting device designed for mounting a specific extinguisher
model onto stationary vertical surfaces.: Extinguisher Hanger
14 A quick check that a fire extinguisher is in its designated place, that it has not been
actuated or tampered with, and that there is no obvious physical damage or condition
to prevent its operation.: Extinguisher Inspection
15. A thorough examination of the fire extinguisher that is intended to give maximum
assurance that a fire extinguisher will operate effectively and safelyand to determine if
physical damage or condition will prevent its operation, if any repair or replacement is
necessary, and if hydrostatic testing or internal maintenance is required.: Extinguisher
Maintenance
16. A solution that will form an aqueous film on liquid fuels: Film-Forming Foam
17. A solution based on fluorinated surfactants plus foam stabilizers to produce a
fluid aqueous film for suppressing liquid fuel vapors.: Aqueous
Film-Forming Foam (AFFF)
18. A protein-foam solution that uses fluorinated surfactants to produce a fluid
aqueous film for suppressing liquid fuel vapors.
Study These Flashcards: FFFP
19. Flammable liquids at least 1/4" deep: Flammable liquids of appreciable depth
20. Pressure testing of the extinguisher to verify its strength against unwanted
rupture.: Hydrostatic testing
21. A water-based extinguishing agent that uses an alkali metal salt as a freezing point
depressant.: Loaded stream extinguisher
22. All steel shells other than stainless steel and steel shells used for high-pressure
cylinders.: Mild Steel Shell
23. The normal operating pressure as indicated on the nameplate or cylinder of a fire
extinguisher.: Extinguisher Service Pressure
24. The pressure shown on the nameplate at which a shell was tested at time of
manufacture.: Factory Test Pressure
25. Fires resulting from liquids that are forced, pumped, or sprayed.: Pressurized
Flammable Liquid Fires
26. The replacement of the extinguishing agent (also includes the expellant for certain
types of fire extinguishers).: Recharge
27. The actual walking distance from a point to the nearest fire extinguisher fulfilling
hazard requirements.: Travel Distance
28. A concentrate that, when added to water, reduces the surface tension and
increases its ability to penetrate and spread.: Wetting Agent Surfactant
29. A fire extinguisher in which the expellant gas is in a separate container from the
agent storage container.: Cartridge/Cylinder Operated
30. A fire extinguisher that is intended to be used one time and not capable of or
intended to be recharged and returned to service.: Nonrechargable
