Fire Hose Operations Instructor: Richard Gichana, Nyeri County Kenya 17 February 2021
Learning Objective 1
u Explain basic fire hose characteristics.
15–1
Each type of fire hose transports water
for on scene operations.
Supply Attack
• From • Water or other
hydrant/water agents at
supply to increased
apparatus pressure
15–2
To be reliable fire hose must be constructed,
used, and maintained appropriately.
• Flexible
• Watertight
Common • Smooth rubber or neoprene
Construction lining
• Covered by durable jacket
• Single-jacket
Common • Double-jacket
• Rubber single-jacket
Configurations • Hard-rubber or plastic
noncollapsable
15–3
Hose size measurements in diameter
refer to the internal diameter.
15–4
Hose size measurements in length refer to a
manufactured section of hose.
Suction
supply
Soft sleeve
hose
Hard
suction
15–5
Fire hose couplings are used to make
connections to hose and equipment.
Designed to National Standards Made of
Form continuous Durable, rustproof
NFPA® 1963
hoseline materials
Connect hoses to Can share between
Various alloys
nozzles, hydrants departments
Connect to pumper
connections and FDCs
15–6
Fire hose couplings are categorized by the
way they are manufactured.
Cast Extruded
Drop
forged
15–7
Threaded couplings have male and
female parts.
15–8
CAUTION
uConnect couplings hand tight to avoid damage to the coupling and
gasket.
15–9Couplings have other parts including
different cuts, sizes, and gaskets.
15–10Lugs and handles help to tighten and
loosen hose connections.
15–11Nonthreaded couplings are
connected with locks or cams.
15–12REVIEW QUESTION
u What are the three basic fire hose characteristics a firefighter must
understand?
15–13Learning Objective 2
u Describe different causes of and prevention methods for hose
damage.
15–14Mechanical damage can occur in several
ways to a fire hose.
Slices, rips,
abrasions, crushed,
cracked
15–15There are many ways to prevent
mechanical damage.
Protect with
Avoid contact Clear broken
hose roller or
with rough, glass from
folded salvage
sharp objects window sills
cover
Prevent vehicles
Use hose ramps
from driving
or bridges
over hose
(Cont.)
15–16There are many ways to prevent
mechanical damage.
Open, close Avoid
Use chafing
slowly to avoid excessive
blocks
water hammer pressure
Change Clean hose
Deploy away
position of before
from debris folds reloading
15–17Thermal damage can result from exposure
to excessive temperatures.
Caused by excessive
heat/cold, direct
flame contact
Can char, melt,
weaken, dehydrate
linings
15–18There are may ways to prevent thermal
damage to fire hose.
Heat
Cold
15–19Organic damage to fire hose can weaken the
jacket and lead to ruptures.
Mildew and mold
15–20Firefighters should know the methods to
prevent organic damage.
15–21There are several types of chemical
damage that may occur to fire hose.
Petroleum
products,
Battery acid
paints, acids,
alkalis
Leftover
water can
Runoff water
form sulfuric
acid
15–22Preventing chemical damage requires
following specific cleaning practices.
Avoid Scrub, wash Dispose of
Test
chemical contaminated according to
periodically
exposure hoselines local SOPs
15–23Corrosion is a type of damage that
weakens or destroys metal hose parts.
Brass
coupling
Aluminum
coupling
15–24Age deterioration is caused by leaving a
hose in an apparatus for a long time.
Prevention
Remove and replace hose
loads periodically
Reload loosely with new
folds
Remove from tower once
dry
15–25REVIEW QUESTION
u How are thermal damage and corrosion in a hose similar or
different?
15–26Learning Objective 3
u Identify basic inspection, care, and maintenance methods for
fire hose.
15–27Inspecting a fire hose requires following a
schedule and reporting process if deficiencies
are found.
15–28The method of washing a hose will depend
on the type of hose.
15–29Drying a hose also requires different
methods for various types of hose.
15–30Storing hose is usually done on racks that
may be mounted or stand free.
15–31CAUTION
uNever store solvents, petroleum products, or other chemicals close
to fire hose and couplings.
15–32There are several methods to prevent
damage to stored hose stored in racks.
Store in clean, Avoid exposure
well ventilated to sunlight,
room pack loosely
Protect Prevent dirt
couplings, roll from collecting
hose with male in sexless
end inside couplings
15–33Fire hose couplings can be damaged even
though designed to be durable.
Male
Female
15–34When caring for fire hose couplings you
should follow these guidelines.
If coupling swivel
General difficult to spin
• Avoid dropping, • Washing machine
dragging insufficient
• Do not drive over • Submerge in warm,
• Inspect when washing soapy water
• Twist swivel in soapy • Clean male threads
water with brush
• Clean threads • Lubricate
• Inspect, replace • Replace damaged
gaskets gaskets
15–35REVIEW QUESTION
u What are the steps taken to perform basic inspection and
maintenance for fire hose?
15–36Learning Objective 4
u Compare various uses for hose appliances and tools.
15–37Hose appliances include a variety of
hardware used in conjunction with hose.
Valves Valve Devices Fittings Intake
• Ball • Wye • Adapters strainers
• Gate • Siamese • Reducers • Attached to
• Butterfly • Water thief drafting end of
• Clapper • LDH - thief hard suction
and manifold when pumping
• Hydrant valve • Designed to
keep debris
from entering
• Preventing
from resting
on bottom
15–38There are several types of hose tools that
firefighters should know about.
Hose Hose
roller jacket
Hose
clamp (Cont.)
15–39CAUTION
uNever stand over the handle of a hose clamp when applying or
releasing it. The handle or frame may pop open and swing upward
violently.
15–40There are several types of hose tools that
firefighters should know about.
Spanner,
hydrant
Hose Chafing
wrench,
bridge/ramp block
rubber
mallet
Hose strap,
LDH roller
rope, chain
15–41REVIEW QUESTION
u What are the types of hose appliances and tools a firefighter
may need to use?
15–42Learning Objective 5
u Describe basic hose rolls.
15–43The straight roll is the simplest of all
hose rolls.
15–44The donut roll is used in situations where the
hose will likely be deployed for use directly
from a roll.
15–45The twin donut roll creates a compact roll
that is easily transported.
15–46The self-locking twin donut roll adds a
built-in carrying loop for the hose.
15–47REVIEW QUESTION
u When should firefighters use basic hose rolls?
