◉ What is the difference between supply hose and attack hose?
Answer: Supply hose: carries water from hydrant/water source to
apparatus with pump
Attack hose: carries water from pump to nozzle/FDC or standpipe to
fire
◉ When is a handline considered "charged"? Answer: When water is
introduced into it
◉ Which NFPA standard manages hose sizes and lengths? Answer:
NFPA 1960
◉ How is hose diameter measured? Answer: Inside diameter
◉ How long is a section of hose? Answer: 50 or 100 ft
◉ What is suction hose? Answer: Intake hose used to connect the
pumper to a hydrant/water source
,◉ Which NFPA standard dictates minimum lengths for suction hose?
Answer: NFPA 1900
◉ What is soft suction hose? Answer: Intake hose used to connect
pumper to a hydrant/water source
◉ Can soft-sleeve hose be used for drafting? Answer: No. It is not
rigid and will collapse.
◉ What sizes is soft-sleeve hose available in? Answer: 2 ½" to 6"
◉ How long is a section of hard suction hose? Answer: 10 ft
◉ What is hard suction hose used for? Answer: Drafting water from
static water supply
Connecting to a fire hydrant
◉ What sizes is hard suction hose available in? Answer: 2 1/2" to 6"
◉ Which NFPA standard manages coupling design and construction?
Answer: NFPA 1960
,◉ What standards must threaded couplings meet? Answer:
American National Fire Hose Connection Screw Threads (commonly
called National Hose or NH)
◉ What is the twisty part of the female coupling called? Answer: The
swivel
◉ What is a shank? Answer: The portion of the coupling that serves
as a point of attachment to the hose
◉ t/f: missing gaskets in couplings always result in leaks Answer:
true
◉ What are lugs? Answer: The grippy/jutting out pieces of couplings
that allow you to manage them easier
◉ Where are lugs located? Answer: Male: shank
Female: swivel
◉ What are the 3 types of lugs? Answer: 1. Pin
2. Recessed
3. Rocker
, ◉ Where might you find pin lugs? Answer: Old fire hose couplings
◉ Why aren't pin lugs used much anymore? Answer: They tend to
catch when hose is dragged over objects or deployed from the hose
bed
◉ Where might you find recessed lugs? Answer: On booster hose
(having lugs that jut out would be problematic since this hose is on a
reel)
◉ How do you tighten or loosen couplings that have recessed lugs?
Answer: You need a pin lug spanner wrench - it should be inserted
into the recessed lug holes to loosen or tighten
◉ What type of lugs are found on modern threaded couplings?
Answer: Rocker lugs
◉ What is a two-way coupling? Answer: A nonthreaded coupling
that does not have distinct male or female characteristics
◉ What are the 2 varieties of two way couplings? Answer: 1.
Quarter-turn
2. Storz
