Cards

Term
Acceptance Testing (Proof Test)
Definition
Preservice tests on fire apparatus or equipment performed at the factory or after delivery to assure the purchaser that the apparatus or equipment meets bid specifications.
Term
Accordion Load
Definition
Arrangement of fire hose in a hose bed or compartment in which the hose lies on edge with the folds adjacent to each other.
Term
Adapter
Definition
 Fitting for connecting hose couplings with dissimilar threads but with the same inside diameter.
Term
Booster Hose or Booster Line
Definition
Noncollapsible rubber-covered, rubber-lined hose usually wound on a reel and mounted somewhere on an engine or water tender and used for the initial attack and extinguishment of incipient and smoldering fires. This hose is most commonly found in 1-inch (13 mm, 19 mm, and 25 mm) diameters and is used for extinguishing low-intensity fires and mop-up.
Term
Dutchman
Definition
Extra fold placed along the length of a section of hose as it is loaded so that its coupling rests in proper position.
Term
Finish
Definition
Arrangement of hose usually placed on top of a hose load and connected to the end of the load. Also called Hose Load Finish
Term
Fire Department Connection (FDC)
Definition
 Point at which the fire department can connect into a sprinkler or standpipe system to boost the water flow in the system. This connection consists of a clappered siamese with two or more 2½-inch (65 mm) intakes or one large-diameter (4-inch [100 mm] or larger) intake.
Term
Fitting
Definition
Device that facilitates the connection of hoselines of different sizes to provide an uninterrupted flow of extinguishing agent
Term
Flat Load
Definition
Arrangement of fire hose in a hose bed or compartment in which the hose lies flat with successive layers one upon the other.
Term
Hard Intake Hose
Definition
A flexible rubber hose reinforced with a steel core to prevent collapse from atmospheric pressure when drafting; connected between the intake of a fire pump and a water supply and must be used when drafting. Also called hard intake hose.
Term
Higbee Cut
Definition
Special cut at the beginning of the thread on a hose coupling that provides positive identification of the first thread to eliminate cross threading.
Term
Higbee Indicators
Definition
Notches or grooves cut into coupling lugs to identify by touch or sight the exact location of the Higbee Cut.
Term
Horseshoe Load
Definition
Arrangement of fire hose in a hose bed or compartment in which the hose lies on edge in the form of a horseshoe.
Term
Hose Bed
Definition
Main hose-carrying area of a pumper or other piece of apparatus designed for carrying hose.
Term
Hydrant Wrench
Definition
Specially designed tool used to open or close a hydrant and to remove hydrant caps.
Term
Nonthreaded Coupling
Definition
Coupling with no distinct male or female components. Also called Storz Coupling or sexless coupling.
Term
Preconnect
Definition
(1) Attack hose connected to a discharge when the hose is loaded; this shortens the time it takes to deploy the hose for fire fighting. (2) Soft-sleeve intake hose that is carried connected to the pump intake. (3) Hard suction hose or discharge hose carried connected to a pump, eliminating delay when hose and nozzles must be connected and attached at a fire.
Term
Reducer
Definition
Adapter 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.
Term
Service Test
Definition
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.
Term
Shank
Definition
Portion of a coupling that serves as a point of attachment to the hose.
Term
Siamese
Definition
Hose appliance used to combine two or more hoselines into one. The siamese generally has female inlets and a male outlet and is commonly used to supply the hose leading to a ladder pipe.
Term
Soft Intake Hose
Definition
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.”.
Term
Spanner Wrench
Definition
Small tool primarily used to tighten or loosen hose couplings.
Term
Split Lay
Definition
Hose lay deployed by two pumpers, one making a forward lay and one making a reverse lay from the same point.
Term
Storz Coupling
Definition
Nonthreaded (sexless) coupling commonly found on large-diameter hose.
Term
Threaded Coupling
Definition
Male or female coupling with a spiral thread.
Term
Water Thief
Definition
Any of a variety of hose appliances with one female inlet for 2½-inch (65 mm) or larger hose and with three gated outlets, usually two 1½-inch (38 mm) outlets and one 2½-inch (65 mm) outlet.
Term
Fire Hose
Definition
a flexible tube to carry water or other extinguishing agents under pressure from a source to a point of application
Term
Supply Hose
Definition
transports water or other agents from a hydrant or source of supply to a pumper at the fire scene.
Term
Attack Hose
Definition
transports water or other agents, at increased pressure, from a pumper to a nozzle or nozzles or a fire department connection for an application onto a fire.
Term
Soft Intake Hose Inside Diameter
Definition
2 1/2'' - 6''
Term
Hard Intake Hose Inside Diameter
Definition
2 1/2'' - 6''
Term
NFPA 1961
Definition

Standard on Fire Hose:

lists specs for fire hose

 

Term
NFPA 1963
Definition

Standard for Fire Hose Connection:

lists specs for hose couplings and screw threads

Term
NFPA 1901
Definition

Standard for Automotive Fire Apparatus:

Requires pumper to carry

15ft of soft intake hose

20ft of hard intake hose

800ft of 2 1/2"

400ft of either 1 1/2", 1 3/4'', or 2'' attack hose

Term

Fire Hose Damage:

Mechanical

Definition
Slices, rips, and abrasions on coverings. Crushed or damaged couplings. Cracked inner linings.
Term

Fire Hose Damage:

Thermal

Definition
Exposing fire hose to excessive heat or direct flame contact that can char, melt, or weaken the outer jacket and dehydrate the rubber lining.
Term

Fire Hose Damage

Organic

Definition
mildew and mold
Term

Fire Hose Damage:

Chemical

Definition

Chemical or chemical vapor can damage the outer jacket or cause rubber lining to separate from jacket.

Reverse Lay

 

Split Lay(combination)

Term

Forward Lay

 

Definition

From water source to fire.

 

Female coupling is the first thing off of hose bed set-up for forward lay.

 

Advantage: pumper at incident to provide equipment at fire

 

Disadvantage: may be necessary for second pumper to boost pressure at the hydrant if water flow is inadequate.

Term
