TFM10 NFPA 24 ACTUAL TEST PAPER QUESTIONS
AND ANSWERS SET A+
✔✔Flow Test - ✔✔A test performed by the flow and measurement of water from one
hydrant and the static and residual pressures from an adjacent hydrant for the purpose
of determining the available water supply at that location.
✔✔Flushing Test - ✔✔A test of a piping system using flow rates intended to remove
debris from the piping system prior to it being placed in service.
✔✔Hydrostatic Test - ✔✔A test of a closed piping system and its attached
appurtenances consisting of subjecting the piping to an increased internal pressure for a
specified period of duration to verify system integrity and leak rates
✔✔Check Valve - ✔✔A valve that allows flow in one direction only.
✔✔Indicating Valve - ✔✔A valve that has components that show if the valve is open or
closed. Examples are outside screw and yoke (OS&Y) gate valves and underground
gate valves with indicator posts.
✔✔Hydrant - ✔✔An exterior valved connection to a water supply system that provides
hose connections
✔✔Dry Barrel Hydrant (Frostproof Hydrant) - ✔✔A type of hydrant with the main control
valve below the frost line between the footpiece and the barrel.
✔✔Flow Hydrant - ✔✔The hydrant that is used for the flow and flow measurement of
water during a flow test.
✔✔Private Fire Hydrant - ✔✔A valved connection on a water supply system having one
or more outlets that is used to supply hose and fire department pumpers with water on
private property.
, ✔✔Public Hydrant - ✔✔A valved connection on a water supply system having one or
more outlets that is used to supply hose and fire department pumpers with water.
✔✔Residual Hydrant - ✔✔The hydrant that is used for measuring static and residual
pressures during a flow test
✔✔Wet Barrel Hydrant - ✔✔A type of hydrant that is intended for use where there is no
danger of freezing weather and where each outlet is provided with a valve and outlet.
✔✔Pressure-Regulating Devices and Meters - ✔✔Shall not be permitted for use unless
acceptable to the AHJ
✔✔Monitor nozzle - ✔✔Shall be inspected semi annually
✔✔Min time for a hydrant flow - ✔✔1 min
✔✔Control valve indicator - ✔✔Shall include identification and signage indicating the
system or portion of the system it controls
✔✔The operating stems of outside screw and yoke os&y valves shall be lubricated -
✔✔Annually
✔✔Each hydrant shall be fully opened and closed at full system pressure - ✔✔True
✔✔Indicates a piece or section that is recommended but is not required - ✔✔Should
✔✔4 times a year- 2 times min a year - ✔✔Quarterly
✔✔Twice per year, 4months min- 8 months max - ✔✔Semi annually
✔✔Once per year: min 9 months- max 15 months - ✔✔Annually
✔✔Exposed piping shall be inspected - ✔✔Annually
✔✔All T's, plugs, caps, bends, reducers, valves, and hydrants shall be restrained by -
✔✔Thrusting blocks
✔✔Thrusting shall be made of - ✔✔Concrete no leaner than 1 part cement and 2.5
parts sand and 5 parts stone
✔✔Any restraining devices such as nuts, bolts, and clamps shall be - ✔✔Coated in a
corrosive retardant substance such as bituminaus
