hose coupling most common material used is
pyrolite
A lightweight coupling made of an aluminum alloy with a hard coating
Durable, lightweight and resistant to corrosion
CFD uses the three-piece coupling for its 38mm and 65mm coupling - Three-piece coupling consists of
A male threaded shank
A female threaded swivel
A non-threaded shank to which the female swivel is attached
One quick way to distinguish the female coupling from the male is to remember that the male shank has lugs and exposed threads while the female shank does not
Storz Couplings
CFD uses on all High-Vol hose
Sexless couplings and may be connected to any other coupling of the same diameter
Hose complement
Refers to the standard sizes and number of lengths of each type of hose carried on CFD apparatus
Engine complement
station complement
storage - rolling hose

o Annually
o After repairs
o After hard use
o On any suspicion of damage
damaged hose
should be tagged and marked and a FD1205 sent to CFD stores
scorpion load
bumper lines (2x15m lengths)
65mm attack bed
It is referred to as the “devils load “or 65 tactical hose bed.
65mm attack bed/devils load is comprised of
three separate stacks, each stack contains 6 lengths of hose that are connected and loaded in two distinct tactical hose configurations, these are:
65mm shoulder load
65mm attack
Making the Snub Loop on 125mm Supply Hose
The snub loop is designed to protect the hose coupling and assist with hose deployment when making a hydrant.
Once the 125mm load is complete, unload approximately 3 m of hose (from the bed to the ground). Fold the hose back on itself, placing the coupling on the same hose length at the end of the bed.
Two types of hose bundles are used by the CFD
Single 15m length of 65mm
Single 30m length of 44mm
Horseshoe load - hose bundles
The hose bundle for the high-rise packs are in a horseshoe load with the male coupling on the inside with the 44 mm nozzle attached, and the female coupling is left unattached on the outside of the bundle
The hose is folded at approximately 32 inches from the tip of the male coupling for ease of carrying
The bundle is secured with three straps
purpose of nozzles
To give the fire stream velocity and shape, so the water can be applied at the right quantity from a safe distance
three main categories of nozzles
handlines
master streams
specialty
three types of master streams
fixed
portable
elevated

Slide type valve controls flow and automatic shut off if monitor is disrupted
** The monitor has three carbide tipped spikes: one on each leg and one on the base. They must be in contact with the ground at all times during operation. **
Blitzfire Safety Feature
The valve handle must be fully closed to reset the safety shut-off mechanism. Placing the monitor on a tilted surface (greater than 10 degrees) may cause a failure in resetting the safety shut-off.
blitzfire tips
stacked tips
fog tip
Stack tips - blitzfire
Supplied tips: 24mm, 32mm, 38mm
New model Blitzfires come with an integrated stream straightener
Delivers between 900-1950lpm at 550kpa nozzle pressure depending on tip selection
blitzfire fog tip
Fully automatic fog nozzle
Dual pressure selection allows for operation at Standard pressure 700 kpa (100 psi) or Low Pressure 420 kpa (~60 psi) nozzle pressure
Pattern control allows for straight stream pattern up to 120-degree wide fog pattern
To place portable monitors into operation, the following steps are necessary:
Place the monitor in the desired location.
Connect hose lines to the intake(s), allowing for approximately 15m of slack for repositioning.
Make sure that hose lines are led in from straight behind (minimum 2 meters).
Before the monitor is charged with water, make sure the footing is secure.
** The monitor’s reach of stream is most effective at 35 degrees of elevation. Care must be taken when operating below 35 degrees due to nozzle reaction. **
specialty nozzles
are broken stream nozzles designed to be used in specific fire circumstances

CFD teaches five methods for coupling/uncoupling hose
One firefighter foot tilt method
Two firefighter method of coupling a fire hose
One firefighter knee press method of uncoupling
Two firefighter stiff-arm method of uncoupling a fire hose
One-firefighter over the hip method
anatomy of a hydrant
opening hydrants
slowly open the hydrant valve until water begins to flow past the seat. Pause to allow the pressure in the barrel to equalize on both sides of the valve before continuing to fully open the hydrant slowly.
Allowing pressure to equalize before opening fully prevents water-hammer and reduces torsional stressors on the hydrant valve stem and couplings
Slowly continue to open the hydrant until fully open, and then turn the hydrant key back one full turn
hydrant closing procedure
set the spindle into the neutral position
The neutral position is located by rotating the operating nut from the fully closed position in a counter-clockwise direction until you feel resistance on the key. Resistance on the hydrant key is caused by the valve starting to open, pushing the disc against the water pressure in the main. The operating nut must be left in the midpoint between fully closed and starting to unseat the disc.
hydrant evolutions or “lays” can be divided into the following
forward lay
reverse lay
initiating a relay operations (cutting in)
surfing the line
term used to describe the procedure for deploying the125 mm hose during reverse lay operations
For safety, it is preferred to surf the hose on the opposite side to the traffic flow.
Position yourself so that the driver can see you in the mirror
Fold the hose back onto itself so that the coupling is in front of the firefighter performing the surfing
Remain surfing the line until 1 - 2 lengths of hose have been deployed and the firefighter no longer feels tension of the hose being pulled
estimating the stretch
estimate the known distance
estimate the foot print size
calculate the number of floors
estimate the known distance
Visible distance from the apparatus to the door of entry
estimate the foot print size
one length should be able to cover a square floor area of 2000ft2
calculate the number of floors
add one length of hose for every level
flaking the hose
Lay the hose on the ground so that it extends to the point of entry. Ensure that there is sufficient covering amount and that the hose is free from kinks and will pay itself into the building with limited chance of snagging on the way once charged with water
3 common techniques of flaking hose
S flake (most common)
U flake (quick option in areas where space is not a problem)
Coil (ideal for limited space/stairwells)
Coil (ideal for limited space/stairwells)
should never be smaller than 1 meter (40inches) in diameter
traditional V stretch
used when space is not an ussie and when there are limited obstructions between the engine and the entry point
hose handling - 44mm handline
requires a min of 2 FF for interior attack
hose handling - 65mm handline
requires a min of 3 FF for interior attack
hose grips
tanaka
clamp
65mm pressure loop
tanaka grip
This technique uses the firefighters skeletal system to take the reactionary force created by the hose line, instead of the using their muscles to counter act force
clamp grip
This technique uses the firefighter’s body weight and low center of gravity to pin the nozzle to ground using back leg and shin thus reducing firefighter fatigue.
65mm pressure loop
This technique allows a single firefighter to operate a 65mm hose line for long periods unassisted.
It should only be used in an exterior application where the firefighter can set up without being in the collapse zone as it may prohibit quick egress by the firefighter
advancing hose lines
over the shoulder
straight arm pull
modified straight arm pull
clamp slide
advancing hose lines - over the shoulder
this method uses firefighter skeletal system to take majority of the weight of hose line instead of using smaller muscle groups
advancing hose lines -straight arm pull
Allows for quick movement that can be sustained for moderate distances
advancing hose lines - clamp slide
Used for advancing both 44mm and 65mm hose lines over short distances
This technique can be used while spraying water
feeding hose
All firefighters within the team must have physical contact on the same hose line and have verbal or visual contact.
