U.S. HIGH-RISE FIRES
18,000 HIGH-RISE FIRES PER YEAR
– 60 CIVILIAN DEATHS
– 33.8% DIE IN A BEDROOM
– 32.6% DIE IN A LIVING ROOM, FAMILY ROOM OR DEN.
– 930 INJURIES
– $642 MILLION PROPERTY LOSS
75% RESIDENTIAL STRUCTURES
– ONLY 25% OF TOTAL DOLLAR LOSS
69% ORIGINATE ON / BELOW THE 4TH FLOOR
22% ORIGINATE ON OR ABOVE THE 50TH FLOOR
AGGRESSIVELY ATTACKING
THE FIRE QUICKLY AND
REACHING THE OCCUPANTS

OUR BEST METHOD TO
ACCOMPLISH SAVING &
PROTECTING LIFE!

Responsibilities
Remember that good hose management is a priority
when leading out and up the stairs and down the
hallway in a commercial or high rise occupancy.
If you don’t have the proper tools and the proper
g.p.m. you can’t complete the task at hand.
Your Engine Co. has wasted their time entering a
commercial structure or a high rise structure without
the proper tools.
It may take another 10 to 15 minutes to get the proper
tools inside to attack the fire.
High Rise Operations
Minimum of 1 3/4“ Hose
Hook up to connection on floor below fire
Check other connections on the way up /
close if open
Know which stairwell has connections
Gated Wye provides for 2nd line
Minimum of 100' of hose - Probably need
more in which case lead with the 2.5” pack then
reduce to the 1.5” pack for attack
Flush connection
Standpipe Bag has all the tools you should need to
make the connection
High Rise Operations
Stretch hose before charged so it don't kink or hang
up.
Solid Stream Nozzle vs. Fog Nozzle
Back up lines
Master streams / RAM
Advise Engineer of floor, hose & nozzle size/type
THERE ARE NO “RE-DO’s”!
IF YOU THINK YOU MIGHT NEED IT,
TAKE IT!
Be Prepared for the Worst
Case Scenario
This 30 year old 16” water main supplies a 30
story high-rise structure.
The actual Opening is 3 ¼” in the pipe.
Stretching in a High Rise
Hose and Valve Cabinets
Don’t use the rack
hose, use your own
hose!
Watch for kinks
caused by the
cabinet when
charging the line
High Rise Packs
Low Pressure Break Apart CHIEF Nozzle with
Built in 1.0” Smooth Bore
100’ 1 ¾” Hose w/ Gated Wye attached
Low Pressure Constant Gallonage Nozzle
At 75 psi flows 150 gpm
1.0” Smooth Bore Shutoff
At 50 psi flows 209 gpm
At 40 psi flows 187 gpm
At 30 psi flows 162 gpm
BREAK-APART
FEATURES
Break-Apart Nozzle
allows for Fog and
Smooth Bore
capabilities at low
pressures.
BREAK-APART
FEATURES
Integral smooth bore allows
more flow at lower pressures
Large orifice easily
passes debris
Threaded end allows “break
and extend” operations
BREAK-APART
FEATURES
Additional high
rise pack can
be attached.
Note: If
attaching to a
NDFD or
SBFD pack
you will need
the Healthwin
Adapter
Standpipes
Standpipe Formula: EP = NP + FL
(supply & attack lines) + Elevation +
25 (for System)
Elevation:
– 5 psi per floor = 1/2 psi / ft
– Add if above grade / subtract if
below grade
What to Pump?
75 psi FL for the Nozzle
25 psi FL in 100’ of 1 ¾” hose
15 psi FL in Supply Hose / Appliances
25 psi FL for the system
5 psi FL per floor
75 + 25 + 15 + 25 = 140psi EP + # of floors
Target flow = 150 gpm
Auto Sprinklers
Maintain 150 psi @ Engine
– Pressure drops = more heads off = more
water needed
Building connections rarely built to withstand
more than 200 psi and they are not normally
tested at higher pressures.
They are rated at an operating pressure of
175 psi
Don’t forget your double-male or double
female adapters when hooking to the building
connection
Flush the debris from the system
before you hook up your attack
lines.
Debris not removed can end up in
the nozzle
Is someone missing a glove?
.
Glove that became stuck in the nozzle after flowing
through the standpipe.
Making the Connection
Bring the Standpipe Bag
Has all of the “extra” tools you should need for
any situation to get water

The Standpipe Bag
Standpipe Bag Contents
Set of Spanners
Pipe Wrench
– For removing stuck caps or turning on valves
Wire Brush
– For removing corrosion or paint from threads
Spare valve hand wheel
Healthwin Adapter
– For adapting to Healthwin cabinets
– For adapting to NDFD or SBFD
– Also located in high-rise pack
Standpipe Bag Contents
Sprinkler Tool
Search Tags
Chalk / Grease Pencils
– For searches, making notes, and marking
pressures on the gauge
20 wood door chocks
Inline pressure gauge
Lightweight elbow
10’ section of 2 ½” hose
Making the Connection
Elbow and hose
allow the
connection to be
made in a tight
area or cabinet
while minimizing
kinks.
Making the Connection
Pressure gauge will show static pressure when
nozzle is closed and flow pressure when nozzle is
flowing. Make sure you note the FLOW pressure.
Storage
Keeping the items connected will make deployment
faster and minimize damage to the threads.
Lining door chocks in the bottom of the bag will
maximize the use of space.
