TFM10 NFPA 24 STUDY EXAMS GUIDE
QUESTIONS AND ANSWERS SET A+
✔✔The following shall not be installed in the service stub between a fire hydrant and
private water supply pipe - ✔✔1. Check valves
2. Detector check valve
3. Backflow preventor
4. Other similar appurtenances
✔✔All piping and fittings and components shall be rated for no less than - ✔✔150psi
✔✔The top of the pipe shall be buried no less than - ✔✔1ft below the frost line
✔✔Any pipe under pressure shall not be buried less than - ✔✔3ft depth/ 4ft for
raidroads
✔✔In no case shall piping be used as - ✔✔Grounding for electrical current
✔✔Piv shall be set so that the top of the post is how many inches above final grade -
✔✔32-40in
✔✔Hydrants shall not be located no less than_____ from a building - ✔✔40ft
✔✔No shut off vakve is permitted on the fdc line from head connection to check valve -
✔✔True
✔✔ NFPA 24 - ✔✔Standard for the Installation of Private Fire Service Mains and Their
Appurtenances
✔✔Texas Insurance Code Chapter 6300 - ✔✔Fire Protection Sprinkler System Service
& Installation
, ✔✔AHJ - ✔✔Authority Having Jurisdiction
✔✔Appurtenance - ✔✔An accessory or attachment that enables the private fire service
main to perform its intended function.
✔✔Automatic Drain Valve (Automatic Drip or Ball Drip) - ✔✔A device intended to
remove water using gravity from piping or valve cavities, which is required to be empty
when the system is not discharging.
✔✔Corrosion-Resistant Piping - ✔✔Piping that has the property of being able to
withstand deterioration of its surface or its properties when exposed to its environment.
✔✔Corrosion-Retarding Material - ✔✔A lining or coating material that when applied to
piping or appurtenances has the property of reducing or slowing the deterioration of the
objects surface or properties when exposed to it environment.
✔✔Fire Department Connection - ✔✔A connection through which the fire department
can pump supplemental water into the sprinkler system, standpipe, or other system,
furnishing water for fire extinguishment to supplement existing water supplies.
✔✔Fire Pump - ✔✔A pump that is a provider of liquid flow and pressure dedicated to
fire protection. A fire pump is a part of a fire standpipe system's water supply and can
be powered by electric, diesel or steam. The pump intake is either connected to the
public underground water supply piping or a static water source (e.g., tank, reservoir,
lake). The pump provides water flow at higher pressure and volume to the standpipe
system risers and hose standpipes.
✔✔Hose House - ✔✔An enclosure located over or adjacent to a hydrant or other water
supply designed to contain the necessary hose nozzles, hose wrenches, gaskets, and
spanners to be used in fire fighting in conjunction with and to provide aid to the local fire
department.
✔✔Hydrant Butt - ✔✔The hose connection outlet of a hydrant
✔✔Hydraulically Calculated Water Demand Flow Rate - ✔✔The waterflow rate for a
system or hose stream that has been calculated using accepted engineering practices.
✔✔Residual Pressure - ✔✔The pressure that exists in the distribution system,
measured at the residual hydrant at the time the flow readings are taken at the flow
hydrants.
✔✔Static Pressure - ✔✔The pressure that exists at a given point under normal
distribution system conditions measured at the residual hydrant with no hydrants
flowing.
