Tandem Pumping

INITIAL SIZE-UP
• When
approaching
the structure
note the
location of the
FDC, Hydrant
and Building
Access.
POSITIONING APPARATUS
• When spotting
the apparatus
for access to
the FDC ensure
the hose lines
will not impede
access to the
building and
angle the
apparatus to
protect the
operator from
traffic.
CONNECTING TO THE FDC
• The Firefighter
stretches the
initial line to
the FDC,
connects the
line and
removes all
caps.
CONNECTING TO THE FDC
• The Engineer
connects the
first line to the
discharge and
stretches the
second line to
the FDC.
SECURING THE HOSELINES
• After the hoses are connected to the apparatus and
the FDC, prior to charging the lines, the Engineer
straightens out the hoses to remove any kinks and
keep the access to the building free of obstruction.
The Engineer then secures the ends of the hose lines
to the apparatus and the FDC. Any couplings will have
the hoses secured within 10’ on both sides.
• A kit containing four rope loops, four tie ropes two
lanyards with clips and a red 2 ½” discharge cap that
has a vent hole drilled in it will be issued to each
apparatus.
SECURING THE HOSELINES
• The hoses at the pump panel are secured using a Lanyard with a loop
on one end and a clip on the other. The Lanyard is secured to the pump
by wrapping it around a discharge or intake and running the clip end
through the loop. It is secured to the hoses using a loop of rope placed
around the hose in a hose knot and attached to the clip.
SECURING THE HOSELINES
• The hoses are then secured to the FDC with the
Lanyard and two rope loops.
SECURING THE HOSELINES
• If there are couplings between the pump panel and the FDC a
rope will be used to secure the hoses with 10’ on both sides of
the coupling. Lay the rope under the hoses, make a round turn
on each side and secure with a square knot.
SECURING THE HOSELINES
• Once the hoses are secured the area surrounding the hoses
must be secured from access by civilians or firefighters due
to the high pressures. Secure an area 25’ on each side of the
hoses with Caution or Danger tape.
CAPPING THE INTAKE RELIEF VALVE
(2006 PIERCE SHOWN)
• Prior to establishing a supply, cap the Front Suction
Intake Relief Valve on 2006 Pierce and the Pump Intake
Relief Valve on H&W’s. A cap equipped with a vent hole
or bleeder valve must be used.
SUPPLY
• The Third In Engine will connect to the FDC and the Fourth In
Engine will supply the Tandem Pumping Evolution through the
front suction. All hose lines and connections are to be away
from the Engineers.
SUPPLY
• The Fourth In Engine establishes a supply and charges the line to the
third In Engine with the pump at idle.
• The Third In Engine opens the intake and then the discharges to the FDC.
Remember to close the tank to pump valve and crack open the tank fill
to bypass 30 - 50 GPM.
SECOND SUPPLY
• If the Third In Engine must establish a supply prior to
the Fourth In Engine arrival a side suction must be used.
SECOND SUPPLY
• When the Fourth In Engine arrives it will supply the
Third In Engine. The Third In Engineer will attach the 5”
supply hose to the front suction.
SECOND SUPPLY
• The Fourth In Engine will
connect the 5” supply for
the Third In Engine to the
large diameter discharge on
the right side of the
apparatus. Once a supply is
established the line will be
filled with the pump at
idle.
• After the discharge valve is
open inform the Engineer
of the Third In Engine the
supply is ready.
SECOND SUPPLY
• Once the supply from the Fourth In Engine is
established the Third In Engine Engineer will:
• Bleed all air from the intake.
• Slowly open the intake.
• Close the first supply.
• Confirm with the Engineer of the Fourth In
Engine they are ready for Tandem Pumping.
• The Fourth In Engine Engineer will then raise the
pump pressure to 200 PSI
