Essentials of Fire Fighting (4th Edition)
Chapter 12 Terms
Fire Hose
Attack Hose
Hose between the attack pumper and the nozzle(s); also, any hose used in a handline to control and extinguish fire. Minimum size is 1 1/2 inch.
Butterfly Loop
Loop made at the beginning of a self-locking twin donut roll which creates the armhold in the finished roll.
Dutchman
Extra fold placed along the length of a section of hose as it is loaded so that its coupling rests in proper position.
Expansion Ring
Malleable metal band that binds fire hose to a threaded coupling by compressing the hose tightly against the inner surface of the coupling.
Female Coupling
Threaded swivel device on a hose or appliance made to receive a male coupling of the same thread and diameter.
Forward Lay
Method of laying hose from the water supply to the fire scene.
Hard Suction Hose
Non-collapsible, rubberized length of hose with a steel core that connects a pump to a source of water and is used for drafting. Also called Hard Sleeve.
Higbee Cut
Special cut at the beginning of the thread to provide positive identification of the first thread and to eliminate cross threading. Also called Blunt Start.
Higbee Indicator
Notch or groove cut into coupling lug to identify by touch or sight the exact location of the Higbee Cut.
Hose Bed
Main hose-carrying area of a pumper or other piece of apparatus designed for carrying hose. Also called Hose Body.
Intake Hose
Hose used to connect a fire department pumper or a portable pump to a nearby water source. It may be soft sleeve or hard suction hose.
Male Coupling
Hose nipple with protruding threads that fits into the thread of a female coupling of the same pitch and appropriate diameter and thread count.
Recessed Lug
Shallow holes drilled into the connections to aid in tightening and loosening connections. Requires the use of a special spanner wrench. Commonly found on booster hose.
Reverse Lay
Method of laying hose from the fire scene to the water supply.
Rocker Lug
Protrusions found on male coupling shanks and female coupling swivels that aid in tightening and breaking connections.
Shank
Portion of a coupling that serves as a point of attachment to the hose.
Snap Coupling
Coupling set with non-threaded male and female components. When a connection is made, two spring-loaded hooks on the female coupling engage a raised ring around the shank of the male coupling.
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.
Split Lay
Hose lay deployed by two pumpers, one making a forward lay and one making a reverse lay from the same point.
Standpipe System
Wet or dry system of pipes in a large single-story or multistory building with fire hose outlets connected to them. The system is used to provide for quick deployment of hoselines during fire fighting operations.
Storz Coupling
Sexless coupling commonly found on large diameter hose.
Supply Hose
Hose between the water source and the attack pumper, laid to provide large volumes of water at low pressure. Also called Feeder Line.
Swivel Gasket
A gasket used to make a hose connection water tight when the male and female ends are connected.
Threaded Coupling
Male or female coupling with a spiral thread.
