deployment of hose can be complicated by which variables? (6)
Size of fire/spill
location of water source
quantity of extinguishing agents
type of extinguishing agent
number of personel
extent of equipment resources
Adapter:
Fitting for connecting hose couplings with dissimilar threads but with the
same inside diameter.
Appliance
Device (other than a coupling) that is used with hose and through which water must pass. The term is applied to any valve, nozzle, fitting, wye, siamese, monitor, or other piece of hardware used in conjunction with fire hose for the purpose of delivering water.
Booster hose
Small-diameter fire hose (3/4␣1 inch), often carried on booster reel, preconnected to pump of an engine (and the booster tank) for putting out small fires near the truck without having to connect to a hydrant easily recovered with a motorized reel. Also known as "Red line" for the common red rubberized outer layer.
Broken Stream
Stream of water that has been disrupted into coarsely divided drops.
Charged line:
fire hose under pressure from the pump at the engine.
Cluster:
A double male and a double female adapter, of the same size, connected
together as a unit.
Clamp:
A device used to clamp fire hose to stop the flow of water
Combination nozzle
A low pressure Fog Nozzle that can be adjusted to produce a near straight stream.
Double female:
fire hose adapter for connecting two "male" couplings together; may also adapt different sizes on either side.
Double male
hose coupling adapter with two male-threaded connectors back-to- back; used for connecting two female couplings together.
Eductor:
A device used to introduce and mix fire chemical into a water stream. An eductor is a fitting with three ports, an inlet for water flow, an outlet for water flow, and an inlet for fire chemical concentrate. The flow of water through the eductor produces a region of lower pressure at the fire chemical inlet, drawing the chemical into the water stream.
Fog Stream:
A fire stream characterized by small droplets of water. The droplets are unable to travel very far, but absorb heat very quickly because of the high surface area they present.
Hard Suction Hose
Non-collapsible suction hose attached to a pump and used to draft water from a source lower than the pump.
Hose bed:
part of fire engine (or hose wagon) where hose is stored for transport and easy access; stocked in layers or rows for quick selection of the desired length, diameter and type of hose; may include hoses "pre-connected" to pump outlets on the engine.
Hose bridge
mechanical ramps permitting vehicle tires to roll over top of hose without pinching or damaging the hose. Sudden hose-pinch can cause dangerous backpressures in a running hose and at the pump and release of the pinch can cause a staggering surge at the nozzle end.
Hose Lay:
Arrangement of connected lengths of fire hose and accessories on the ground, beginning at the first pumping unit and ending at the point of water delivery
Hose Reel
A rotating drum used for winding Red Line/Booster Hose(normally) for storing and dispensing
Hydrant Wrench
tool for opening valves, or removing caps of fire hydrants; may be simple spanner, box wrench, or adjustable wrench,
Forward Lay
Laying hose from the water source to the fire.
Reverse Lay
Laying hose from the fire to the water source.
Straight Lay
laying hose from the water source to the fire with the engine returning to the water source to pump.
Nozzle tip:
Portion of firehose that forms the fire stream as it leaves the hose. Can be solid, fog, or other specialty nozzle (e.g., piercing, Bresnan cellar nozzle, wand tip, etc.).
Pre-connect
Firehose on a fire engine that has one end connected to a pump outlet, and usually a nozzle on the other end. May also be a preconnected inlet hose (e.g., soft suction).
Working line␣
generally foward or straight lay Refers to 200 feet of 2 1⁄2 inch hose to be flaked for fire attack. Also the portion of the hose lay used for fire attack.
Red Line:
See "Booster Hose"
Running line␣
generally referred to during stright or reverse lay. The
portion of the hose used for supplying the fire attack lines.
Siamese
Hose appliance for merging two shoes lines into one.
Soft suction hose
A short piece of fire hose, usually 10 to 20 feet long, of large diameter, greater than 2.5 inches and as large as 6 inches, used to move water from a fire hydrant to the fire engine, when the fire apparatus is parked close to the hydrant.
Solid Stream
A fire-fighting water stream emitted from a smooth-bore nozzle. This fire-fighting stream has the greatest reach and largest drops of water
Spanner
rigid tool for tightening or loosening firehose couplings.
Straight Stream
A fire-fighting water stream generated by a combination nozzle, characterized by a long reach and large water drops. It is essentially the narrowest of fog patterns that can be produced.
Half or Full strip
The ␣␣trip␣ is the fast, systematic, removal of pre- designated equipment in conjunction with a hose lay. When the Company Officer ␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣trip␣, the following equipment is quickly removed from the apparatus:

"CLAMPS"
Clamp
Ladder
Axe
Medical
Pike pole or Rubbish Hook
Spare SCBA Bottles
Full Strip

"STIHL"
Saw
Tarps
Irons
Hall Runners
Lights
Supply line
fire hose, usually 2.5 inches in diameter or up to 5 inch, used to transport water from one source to another, such as from a hydrant to a fire engine or from one engine to another. Short pieces of this hose used to attach to a hydrant are often called "Soft Suction"
Wedges
Wooden blocks for temporary shut-off of activated sprinkler heads or holding doors open during firefighting or rescue operations.
Wye:
hose coupling for splitting one line into two or more outlets, often a larger line split into two smaller ones; often a gated wye having separate valves for each outlet. Not to be confused with Siamese, which is used to bring two smaller lines together into one.
