What type of hose transports water from the pumping apparatus to the nozzle where it is applied to the
fire? - Answer: Attack hose
A fire hose is labeled or describe according to the size of its - Answer: Inside diameter and length
Which type of hose is designed to connect the pumping apparatus to a pressurized water source -
Answer: Large diameter soft sleeve or soft suction
Generally constructed in 10 foot long sections designed for drafting water from static water supplies or
connecting to a hydrant. - Answer: Hard suction hose
Why is it advantageous for departments to use hose with national standard threaded couplings? -
Answer: Using fire hose with national standard thread means that two or more fire departments that
respond together can connect their fire hose sections.
Threaded couplings must meet the dimensions required of ? - Answer: National hose (NH) AKA American
national Fire hose screw threads.
This standard specifies fire hose coupling design and construction to ensure compatibility with all brands
of fire hose - Answer: NFPA 1963 standard of fire hose connections.
, If a Jurisdiction does not use a national standard thread when connecting to a hydrant or apparatus
mutual aid (. ) may be needed to complete the connection. - Answer: Hose adapters
This coupling thread is cut on the exterior surface - Answer: Male coupling
This coupling thread is on the interior surface of a free turning ring called a swivel - Answer: Female
coupling
The portion of the coupling that serves as the point of attachment to the hose is called the _____. -
Answer: Shank
A flattened angle at the end of the threads of on the male and female couplings that prevents cross
threading when couplings are connected. - Answer: Higbee cut
Specifications for fire hose standard and sizes - Answer: NFPA 1961 standard on fire hose
(indentation) on the exterior of the coupling marks where the Higbee cut, begins; it also aids in matching
the male coupling thread to the female coupling thread during low lighted situations or when the
threaded end of the coupling is not visible - Answer: Higbee indicator
Threaded couplings are manufactured with either (. ) or (. ) to be used as grasping points and aid in
tightening and loosening connections - Answer: Lugs or handles
Special tool that connections can be made manually with - Answer: Spanner wrenches
What three type of lugs are found for fire hose? - Answer: Pin, recessed, and rocker
Usually found on old fire hose couplings, resemble small pegs however, are infrequently ordered with
new fire hoses because they tend to catch when the hose is dragged over objects or deployed. - Answer:
Pin lugs
