Study Notes

Attaching a Nozzle

Position left leg to form a work table above the knee, grasp hose coupling with the left hand.
Perform a visual gasket check before attaching nozzle to hose coupling.
Hold hose with left hand behind coupling while breaking the nozzle over the left hand (tip pointing downward).
Use right hand to shut off the nozzle after breaking it.
Pivot hose 180 degrees counterclockwise, relocating nozzle over the back of the right shoulder.

Removing a Nozzle

Utilize both hands to pick up the nozzle, right hand should grip the nozzle tip.
Left hand forms a work table on the left leg, holding hose coupling.
Regain grip of nozzle with right hand at the shut-off butt or double male.
Break the seal of the gasket before removing the nozzle from hose coupling.

One Member Fold

Flake out a section of hose, ensuring it is flat and straight.
Break coupling while retaining male coupling in the left hand and bed female coupling with right hand.
Attach the correct nozzle (not a double male) to the male coupling, ensuring it is shut off.
Place the nozzle over the back of the right shoulder while facing the flaked hose.
Disconnect 4" hose from 4-way valve, leaving increaser attached.

Hose Operations

Nozzle member shoulders 4" coupling and pulls hose to officer's location.
Connect 4" line from engine to 4" double male previously attached to the line from the 200 Series engine.
Check for kinks in the hose line after making final connections.
Hydrant member instructs engine to "take off" for relocation to the hydrant once the area is clear.

Supply Line Management

Assert "take off" command when the hydrant member returns to their jumpseat; engine proceeds to the fire.
Officer designates the hose lay type.
Hydrant member pulls a running line from engine and dresses it for deployment.
Engineer acquires proper fittings for suction inlet (4" double female) and relieves the hydrant member.
Shoulder male coupling on the inside shoulder for connection at the suction inlet while the engineer calls for "water."

Advancing Hose Lines

Nozzle member removes firefighting line from the apparatus.
Advance 1-1/2" or 1-3/4" line to the closest ladder beam, coordinating with other members.
Couple up hoses according to ladder positioning, placing couplings aligned straight from the center of the ladder rungs.
Hydrant member assists nozzle member in advancing the appropriate number of couplings post-hydrant retrieval.

Ladder Operations

Nozzle member regains and shoulders the nozzle in preparation for ladder ascent.
Hydrant member shouldered 25 feet behind the nozzle member, readying to advance.
Ascend the ladder after ensuring hose line is appropriately managed.
Hydrant member follows the nozzle member when the hose loop reaches knee height.
Aboveground team hoists and flakes hose line as it is pulled into their location.
Signal for "water" once adequate hose length is pulled up to the fire floor.
