FIREFIGHTER 1 TEST EVALUATION ANSWERS AND
QUESTIONS SET A+
✔✔bleed air - ✔✔what should you do before entering a building with a hoseline?
✔✔fire stream - ✔✔stream of water of other extinguishing agent after it leaves a fire
hose nozzle until it reaches the desired target
✔✔broken stream - ✔✔This stream has greater reach and penetration than a fog
stream.
✔✔50 psi - ✔✔When smooth bore nozzles are used on handlines, they are usually
operated at what pressure?
✔✔small-diameter hose - ✔✔3/4 inch to 2 inches in diameter hoseline
✔✔indirect - ✔✔attack is made through a window or other opening, directing the stream
toward the ceiling to cool the room
✔✔aqueous film forming foam - ✔✔Synthetic foam concentrate that, when combined
with water, can form a complete vapor barrier over fuel spills and fires and is a highly
effective extinguishing and blanketing agent on hydrocarbon fuels
✔✔attack hose - ✔✔Hose that is used by trained firefighters to combat fires.
✔✔Bedded position - ✔✔Extension ladder with the fly section(s) fully retracted.
✔✔Combination attack - ✔✔Extinguishing a fire by using both a direct and an indirect
attack
✔✔Critical flow rate - ✔✔The minimum flow rate at which extinguishment can be
achieved.
, ✔✔Drafting - ✔✔Process of acquiring water from a static source and transferring it into
a pump that is above the source's level; atmospheric pressure on the water surface
forces the water into the pump where a partial vacuum was created.
✔✔Fire alarm control panel - ✔✔System component that receives input from automatic
and manual fire alarm devices and may provide power to detection devices or
communication devices.
✔✔Fire point - ✔✔Temperature at which a liquid fuel produces sufficient vapors to
support combustion once the fuel is ignited. The fire point is usually a few degrees
above the flash point.
✔✔Flowmeter - ✔✔Mechanical device installed in a discharge line that senses the
amount of water flowing and provides a readout in units of gallons per minute (liters per
minute).
✔✔Fulcrum - ✔✔The support or point of support on which a lever turns in raising or
moving something
✔✔Heat release rate - ✔✔Total amount of heat released per unit time
✔✔Hydraulic ventilation - ✔✔Ventilation accomplished by using a spray stream to draw
the smoke from a compartment through an exterior opening.
✔✔Improved explosive device - ✔✔IED
✔✔Incendiary device - ✔✔Material or chemicals designed and used to start a fire.
✔✔Kerf cut - ✔✔A single cut the width of the saw blade made in a roof to check for fire
extension.
✔✔Nader pin - ✔✔Bolt on a vehicle's door frame that the door latches onto in order to
close.
✔✔Neutral plane - ✔✔The level at a compartment opening where the difference in
pressure exerted by expansion and buoyancy of hot smoke flowing out of the opening
and the inward pressure of cooler, ambient temperature air flowing in through the
opening is equal.
✔✔Nozzle reaction - ✔✔Counter force directed against a person holding a nozzle or a
device holding a nozzle by the velocity of water being discharged.
✔✔Point of no return - ✔✔Point at which air in the SCBA will last only long enough to
exit a hazardous atmosphere.
