1. Arrival on scene:
a.
Lay a 3-inch supply line to the
fire scene from a hydrant or from a convenient location for relay hook-up
from a Maxipumper, such as the beginning of a driveway.
b.
Stop pumper in a safe position
that gives adequate access, but does not block access for subsequent
apparatus.
c.
Place transmission in neutral, engage parking brake.
d. Engage Power Take-Off (PTO) by depressing clutch and pulling Pump-Shift Knob over
transmission up fully. Release the clutch, a noticeable change in sound
will be heard.
e.
Set wheel chocks.
2.
Water-tank operation:
a.
Open "tank-to-pump" gate.
b.
Advance throttle until
compound-gage pressure reaches 75 -
100 psi. (If necessary, prime pump until pressure registers on
compound gage.)
c.
Open appropriate discharge gates [Ensure
that hose is fully out of bed.]
d.
Advance throttle until compound-gage pressure reaches 125
psi.
e.
Monitor water supply. Keep
officer informed of water supply. Watch and listen for signs of running
out of water, such as sudden drop in compound-gage pressure. Upon loss of
water, immediately shut down pump until a supply line is hooked up and a
water supply re-established.
3.
Supply-line operation:
a.
Connect 3-inch supply line to
suction inlet.
b. Open "suction inlet" gate,
slowly.
c.
Open appropriate discharge gates. [Ensure that hose is fully out of
bed.]
d. Advance throttle until compound-gage pressure reaches 125
psi.
4.
Combined Water-Tank and Supply-Line Operation:
a.
Proceed through Water-tank
operation (Section 2 above).
b.
Connect the 3-inch supply line to suction inlet.
c. Open "suction inlet" gate, slowly, watching compound
gage pressure.
d. Retard throttle to maintain 125 psi
as the water supply reaches the pump. [If pumping from tank and the
suction intake is opened, the 100 psi pressure in the Hackensack water
system will add to the at 125 psi pump pressure to give 225 psi -
dangeriously too
much to control at the nozzle.]
e. Close the tank-to-pump gate immediately. [Back flow of municipal water through the pump into the tank may
(and has) burst the tank on R-1.]
5.
Attack lines:
a. Booster lines: Open Left and/or Right Booster Gate(s). Pull sufficient hose from
reels. [125 psi provides a 20 GPM flow through 100-feet of 1-inch hose.]
Booster lines should be used only
for brush fire or wash-down purposes. There is insufficient flow for
knockdown of any other type of fire and, as such, can be a danger to
firefighters.
b. 1-1/2 attack lines: Remove line(s) completely from hose beds. Open left and/or right Preconnect
Gate(s)
when requested.
c.
Adjust pressure to 125 psi at
discharge gate pressure gage(s). [125 psi provides a 60 GPM flow through
200-feet of 1/2-inch hose.;
165 psi produces 100 GPM which is the limit of the nozzle]
d. Foam:
(1) Use LEFT 1-1/2-inch PRE-CONNECT only.
(2) Rotate valve over the pump panel to
educt foam from the 12-gallon foam tank into the left pre-connect
discharge.
(3) Increase discharge pressure to 175
psi to educt foam. [Foam will not aspirate through the eductor without
sufficient pressure.]
1. Arrival on scene:
a. Lay a 5-inch supply line
to the fire scene from a hydrant .
b. Stop pumper in a safe position
which gives adequate access, but does not block access for
subsequent apparatus.
c. Place transmission in neutral, engage
parking brake.
d.
Engage Power Take-Off
(1)
Pull
Pump-Shift Knob out fully (located on left side of dash panel). [If knob does not move, it may be in locked position. Rotate knob,
then pull out]. Adjacent amber "pump-indicator" lights up when
PTO engages.
(2)
Place
transmission in drive. Engage
safety latch on gear
shift.
e. Set wheel chocks.
2. Water-tank operation:
a. "Pump-Indicator" light
must be green on pump panel. [If not on, repeat above steps for
engaging PTO.]
b. Pressure-Volume valve
must be at VOLUME setting.
c. Open "tank-to-pump" gate.
d. Advance throttle
until
compound-gage pressure reaches 75 -
100 psi. [If necessary,
prime pump until pressure registers on compound gage.]
e.
Determine which hose and discharge port is to be used. [Ensure that
hoses are fully out of beds before charging.]
f.
Open appropriate discharge gates
when water is called-for.
g. Adjust throttle
until
compound-gage pressure reaches 125
psi.
h.
Monitor water supply.
Keep
officer informed of water supply. Watch and listen for signs of running
out of water, such as sudden drop in compound-gage pressure. Upon loss of
water, immediately shut down pump until supply line is hooked up and water
supply re-established.
3. Supply-line operation:
a. Connect 5-inch supply line
to suction inlet. Signal the hydrant man to open the hydrant.
b.
Bleed line of air,
using the intake manifold bleed cocks.
c. Open "suction inlet" gate,
slowly. Note increase in pressure on the compound gage.
d.
Determine which hose and discharge port is to be used. [Ensure that
hoses are fully out of beds before charging.]
e. Open appropriate discharge gates.
f. Advance throttle
until compound-gage pressure reaches 125
psi
g. Monitor water supply.
Keep
officer informed of water supply and Incident Command Officer informed of
any drop in supply pressure. Watch and listen for signs of running out of
water, such as sudden drop in compound-gage pressure or softening of
supply line. Upon loss of water, immediately shut down pump until supply
is restored. [Try to anticipate
interruption of water supply so that hose teams can be backed out before
total loss occurs.]
4. Combined operation:
a.
Proceed through Water-tank
operation (Section
2 above).
b.
Connect the 5-inch supply line to "suction inlet".
c.
Bleed line of air, using
bleed cocks on intake manifold.
d.
Open "suction inlet" gate slowly, watching compound
gage pressure.
e.
Retard throttle to maintain 125 psi
as the water supply reaches the pump. [When pumping from tank and the
suction intake is opened, the 100 psi pressure in the Hackensack water
system will add to the at 125 psi pump pressure to give 225 psi - far too
much to control at the nozzle.]
f. Close the tank-to-pump gate immediately. [Back flow of municipal
water through the pump into the tank may (and has) burst tanks.].
g.
Re-fill tank when time permits, using "Tank-Fill" gate.
5.
2-inch Attack Lines:
a.
2-inch PRE-CONNECTS: Remove line(s) completely
from hose beds. Open Preconnect Gate(s) when requested. If a gated wye-reducer
is attached to a discharge port, ensure that the appropriate gated wye is
open.
b.
Adjust pressure to 125 psi at opened discharge gate pressure
gage(s). 125 psi provides
a 125 GPM flow through 200-feet of 2-inch hose; 150 psi provides 200 GPM
which is the limit of the automatic nozzles.
c.
Foam:
(1) Insert foam eductor into line using
10-foot section of 2-inch hose.
(2) Increase discharge pressure to 175
psi to educt foam. [Foam will not aspirate through the eductor without
sufficient pressure.]
(3) Use portable aspirator to suck up foam
from 5-gallon foam buckets.
6.
Master streams:
a.
Sprinkler lines:
(1) Run a 3-inch line from a 2½-inch
discharge to the sprinkler connection.
(2) Charge line at no more than municipal
pressure (125 psi or less) .
(3) Run a second 3-inch line from another 2½-inch discharge port to the sprinkler
connection.
b.
3-inch and 5-inch supply lines:
(1) Run one 3-inch line from a 2½-inch discharge port or a 5-inch line from the married 5-inch discharge port to
the appropriate suction intake.
(2) Charge and maintain supply line at
municipal pressure (125 psi or less).
c.
3-inch manifold lines:
(1) Run a 3-inch line from a 2½-inch discharge port to a 2-1/2-inch
gated wye reducer. Two 2-inch attack lines run from the gated wye.
(2) Maintain a pressure of 150 psi. [Longer hose lays require only slightly higher pressure. ]
d.
5-inch manifold lines:
(1) Run a 5-inch line from the 5-inch
discharge port to a 5-inch manifold.
(2) Maintain a pressure of 125 - 150 psi. Four 2-inch or 2-1/2-inch
attack lines can run from a manifold supplied by a 5-inch line.
e.
2-1/2-inch Hand lines:
(1) 2-1/2-inch master streams may be connected to discharge ports, gated wye
reducers, or 5-inch manifolds.
(2) 2-1/2-inch
hand lines are charged at 125 psi,
which provides a 250 GPM flow through 200-feet of 2-1/2-inch
hose. It will take two or three firemen at the nozzle to control this
line.
f.
Deluge gun:
(1) Use open-bore tips of the largest
possible size for maximum penetration into a large body of fire.
(2) Use the adjustable
nozzle 500 GPM nozzle for smaller fire and exposure protection.
(3) Use the 250 GPM aspirating nozzle for foam.
