Heavy Stream Devices
A. Portable Devices:
Cleveland Fire Department
Operations Manual
1. A deluge set may be operated from the apparatus or on the ground.
2. A deluge set shall be operated as prescribed earlier in this procedure.
B. Fixed Devices:
1. A deck gun is permanently mounted above the pump, between the cab and the hose bed.
2. Some deck guns are pre-piped from the pump and some require the use of 2-½ inch or 3
inch hose hooked to pump outlets.
3. The apparatus on which a fixed heavy stream device is mounted must be carefully and
correctly positioned at the fire scene.
C. Elevated Streams:
1. Elevated streams are managed by Truck Companies, although they must be supplied by
Engine Companies.
2. An effective stream requires coordination between both Companies.
D. Nozzles -- Solid Stream:
1. Nozzle pressure and flow
1¾-inch -- 80 psi -- 800 gpm
2-inch -- 80 psi -- 1000 gpm
2. If water supply is a problem, a smaller nozzle must be used.
A 1¼- inch tip may be used on a heavy stream device when there is not enough water flow to feed
the nozzles listed above. 1¼-inch -- 80 psi -- 400 gpm
E. Nozzles -- Fog:
1. Should be operated at 100 psi to deliver 350-2000 gpm.
2. Some fog nozzles are adjustable-gallonage. Example: -- 350, 500, 750, and 1000 gpm.
3. A 500 gpm stream from a 500 gpm nozzle will be much more effective in controlling a
fire than an inadequate stream from a 1000 gpm nozzle.
