Chapter 14: Water Supply Flashcards
Accordian Load
Arrangement of fire hose in a hose bed or compartment in which the hose lies on edge with the folds adjacent to each other.
Adapter
Device for connecting hose couplings with dissimilar threads but with the same inside diameter.
Attack Hose
Hose that is used by trained firefighters to combat fires.
Booster Hoseline
Noncollapsible rubber-covered, rubber-lined hose usually wound on a reel and mounted somewhere on the apparatus and used for extinguishment of incipient and smoldering fires. This hose is most commonly found in ½ -, ¾-, and 1-in (13mm, 19mm, 25mm) diameters and is used for extinguishing low-intensity fires and overhaul operations.
Dutchman
Extra fold placed along the length of a section of hose as it is loaded so that its coupling rests in proper position.
Finish
Arrangement of hose usually placed on top of a hose load and connected to the end of the load.
Fire Department Connection (FDC)
Point at which the fire department can connect into a sprinkler or standpipe system to boost the water flow in the system.
Fire Hose
A flexible, portable tube manufactured from watertight materials in 50 to 100 ft (15 to 30 m) lengths that is used to transport water from a source or pump to the point where it is discharged to extinguish fire.
Fitting
Device that facilitates the connection of hoselines to provide an uninterrupted flow of extinguishing agent.
Flat Load
Arrangement of fire hose bed or compartment in which the hose lies flat with successive layers one upon the other.
Four-Way Hydrant Valve
Hose appliance that is attached to the hydrant to permit additional supply hoses to be attached without interrupting the flow of water.
Hard-Suction Hose
Rigid, noncollapsible hose that operates under vacuum conditions without collapsing, allowing a pumping apparatus or portable pump to “draft” water from static or nonpressurized sources (lakes, rivers, wells, etc.) that are below the elevation level of the fire pump, usually available in 10-ft (3m) sections.
Higbee Cut
Special cut at the beginning of the thread on a hose coupling that provides positive identification of the first thread to eliminate cross-threading.
Higbee Indicators
Notches or grooves cut into coupling lugs to identify by touch or sight the exact location of the Higbee Cut.
Horseshoe Load
Arrangement of fire hose in a hose bed or compartment in which the hose lies on edge in the form of a horseshoe.
Hose Bed
Main hose-carrying area of a pumper or other apparatus designed for carrying hose.
Hydrant Wrench
Specially designed tool used to open or close a hydrant and to remove hydrant caps.
Nonthreaded Coupling
Coupling with no distinct male or female components. Also known as Storz Coupling or sexless coupling.
Open Butt
The end of a charged hoseline that is flowing water without a nozzle or valve to control the flow.
Preconnect
Attack hose connected to a discharge when the hose is loaded; this shortens the time it takes to deploy the hose for fire fighting.
Quarter-Turn Coupling
Nonthreaded (sexless) coupling with two hook-like lugs that slip over a ring on the opposite coupling and then rotate 90 degrees clockwise to lock.
Reducer
Fitting used to attach a smaller hose to a larger hose. The female end has the larger threads, while the male end has the smaller threads.
Service Test
Series of tests performed on apparatus and equipment in order to ensure operational readiness of the unit. These tests should be performed at least yearly or whenever a piece of apparatus or equipment has undergone extensive repair.
Shank
Portion of a coupling that serves as a point of attachment to the hose.
Siamese
Hose appliances used to combine two or more hoselines into one. The Siamese has multiple female inlets and a single male outlet. An example of a Siamese is a FDC.
Soft Sleeve Hose
Large-diameter collapsible piece of hose used to connect a fire pump to a pressurized water supply source; sometimes incorrectly referred to as soft suction hose.
Spanner Wrench
Small tool primarily used to tighten or loosen hose couplings; can also be used as a prying tool or a gas key.
Storz Coupling
Nonthreaded (sexless) coupling commonly found on large-diameter hose. Nonthreaded fire hose couplings have been used in the North American fire and emergency services since the early 1900s. With this type of coupling, the mating of two couplings is achieved with locks or cams without eh use of screw threads.
Supply Hose
Hose that is designed for the purpose of moving water between a water source and a pump that is supplying attack hoselines or fire suppression systems.
Suction Hose
Intake hose that connects pumping apparatus or portable pump to a water source.
Threaded Coupling
Male of female coupling with a spiral thread.
Water Thief
Any a variety of hose appliances with one female inlet for 2 1/2-in (65mm) or larger hose and with three gated outlets, usually two 1 1/2-in (38mm) outlets and one 2 1/2-in (65mm) outlet.
Wye
Hose appliance with one female inlet and multiple male outlets, usually smaller than the inlet. Outlets are also usually gated.
