Master Stream Operations
Pre-piped
And
Ground Monitors
Objectives
1. Review Strategic and Tactical
Applications
2. Friction Loss
3. Deployment and Operations
Master Streams
Used to produce high volume water streams
for large fires
Several types
Deck Gun and Portable Monitor
500-1000 GPM
Master Streams
Three main uses for a master stream
1. Direct fire attack
2. Back-up handlines that are already
attacking the fire from the exterior
3. Exposure protection
-Vapor suppression for Haz Mats
Placement of the Master Stream
Properly positioned before charging
What are your considerations for placement
at for a structure fire application?
There are three basic considerations
Placement
1. Close enough to reach the seat of the
fire.
2. Upword angle at which the stream
enters the building
3. Maximum Coverage

Optimal Distance
Ground Monitor
For every 1’ in vertical height needed
place the monitor 1’ away from intended
target
45 Degrees is maximum angle with a desirable
stream
Should have ability to reach up to 3 stories
Deck Gun 4 stories
Best angle for penetration is 30-34 degrees.
Optimal Operating Angles
for
Safety
Generally no lower than 25 degrees
Do not go past the transversing range
Generally there is a set pin
