NFPA 10 Exam
A colorless, odorless, electrically nonconductive inert gas that is a suitable medium for extinguishing
Class B and Class C firesANSWERCarbon Dioxide
A powder composed of very small particles, usually sodium bicarbonate, potassium bicarbonate, or
ammonium phosphate-based with added particulate material supplemented by special treatment
toprovide resistance to packing, resistance to moisture absorption (caking), and the proper flow
capabilitiesANSWERDry Chemical
Normally an aqueous solution of organic or inorganic salts or a combination thereof that forms an
extinguishing agent.ANSWERWet chemical
Electrically non-conducting, volatile, or gaseous fire extinguishant that does not leave a residue
uponevaporation.ANSWERClean Agent
A system that is constructed in a manner that does not introduce foreign material into the agent
being recovered and has a means of visually inspecting the recovered agent for
contaminants.ANSWERDry Chemical Closed Recovery System
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 agent escapes to
the atmosphere.ANSWERHalogenated Closed Recovery System
Cylinders (and cartridges) containing nitrogen, compressed air, carbon dioxide, or other gases at a
pressure higher than 500 psi (3447 kPa) at 70°F (21°C).ANSWERHigh-Pressure Cylinder
Cylinders containing fire extinguishing agent (medium), nitrogen, compressed air, or other
compressed gases at a service pressure of 500 psi (3447 kPa) or lower at 70°F (21°C).ANSWERLow-
Pressure Cylinder
Solid materials in powder or granular form designed to extinguish Class D combustible metal fires by
crusting, smothering, or heat-transferring means.ANSWERDry Powder
, 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.ANSWERElectronic Monitoring
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.ANSWERExtinguisher Bracket
An identifiable and readily accessible fire extinguisher housing device designed to store and protect
fire equipment.ANSWERExtinguisher Cabinet
Extinguisher mounting device designed for mounting a specific extinguisher model onto stationary
vertical surfaces.ANSWERExtinguisher Hanger
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.ANSWERExtinguisher Inspection
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.ANSWERExtinguisher Maintenance
A solution that will form an aqueous film on liquid fuelsANSWERFilm-Forming Foam
A solution based on fluorinated surfactants plus foam stabilizers to produce a fluid aqueous film for
suppressing liquid fuel vapors.ANSWERAqueous Film-Forming Foam (AFFF)
A protein-foam solution that uses fluorinated surfactants to produce a fluid aqueous film for
suppressing liquid fuel vapors.
