Term
Common fire hose lengths
Definition
50-100 feet
Term
NFPA Standard on Fire Hose
Definition
1961
Term
NFPA Standard on Automotive Fire Apparatus
Definition
1901
Term
How much fire hose should pumpers carry?
Definition
15 ft of large soft intake or 20 ft of hard intake; 800 ft of 2 1/2 or larger; and 400 ft of 1 1/2, 1 3/4, or 2 attack hose
Term
Hose washes wash up to what size?
Definition
3 inches
Term
Materials to make couplings
Definition
brass, aluminum, or magnesium
Term
Three types of lugs
Definition
pin, rocker, and recessed; rocker is the most common
Term
Wye appliance
Definition
divides a single hoseline into two or more lines

all wyes have a single female and two male
Term
Siamese appliance
Definition
two hoselines going into a single

two female and one male
Term
Water thief
Definition
most common in wildland operations; most commonly a 1 1/2 female inlet, a 1 1/2 male outlet, and one valve-controlled 1 inch male outlet
Term
LDH manifold
Definition
one LDH inlet and three 2 1/2 valve-controlled male outlets
Term
Hydrant valve
Definition
used when a forward lay is made from a low-pressure hydrant; allows original supply line to be connected and charged, fed into additional hoselines, and then boosted by another pumper
Term
Fitting
Definition
facilities the connection of hoselines of different diameters and thread types
Term
Adapter
Definition
fetting for connecting hose couplings with dissimilar threads and the same diameter (double-male, double-female)
Term
Reducer
Definition
connect a smaller hoseline to the end of a large one

may be wiser to attach a wye so two hoselines are supplied
Term
Elbows
Definition
provide support for intake or discharge hose at the pumping apparatus by preventing kinks
Term
Hose cap
Definition
protects male pump discharge
Term
Hose plugs
Definition
protects FDC female inlets
Term
Intake strainer
Definition
attached to the drafting end of a hard intake to prevent debris from entering the pump

must not rest on the bottom of a static water source EXCEPT when bottom is clean and hard (eg. swimmping pool)
Term
Hose jacket
Definition
hinged, two-piece cylinder that seals a rupture in a hose line

made in two sizes; 2 1/2 and 3 inches

Effective enough to continue to operate at full pressure
Term
Hose clamp
Definition
stops the flow of water in a hoseline
Term
Hose bridges
Definition
used when vehicles must drive over a hoseline
Term
Straight roll
Definition
rolls around male coupling, female is exposed

used when loading back on to the apparatus at the scene, returning to quarters for washing, or placed in storage
Term
Donut roll
Definition
used in situations where hose is likely deployed directly for use from roll

firefighter has control of both couplings, rolls out easier with fewer kinks, holding both couplings facilitates connecting other couplings, even in the dark
Term
Twin donut roll
Definition
creates a compact roll that can be easily transported and carried (eg. highrises)
Term
Self-locking donut roll
Definition
twin donut roll with a built-in carrying loop formed by the hose itself
Term
Dutchman
Definition
changes the direction of a coupling in the load, and changes its location; coupling is not too close to the rear or front of the hose bed and will not flip over when pulled out
Term
Accordion Load
Definition
simple design; hose lays on it's side and in even folds

only two or three people needed to load; shoulder carries can be easily taken by picking up a number of folds
Term
Horseshoe Load
Definition
loaded on edge with a U-shaped configuration; no longer widely used

has fewer sharp bends, but comes out in a mess when pulled
Term
Flat Load
Definition
easiest to load and most common; folds lie flat, but there are sharp bends

can be used for LDH and pulled off as pumper moves
Term
Straight Finish
Definition
Last length or two of hose flaked loosely back and forth across the top of the load; usually associated with a forward-lay operation
Term
Reverse Horseshoe finish
Definition
bottom of the 'U' portion of the horseshoe is at the rear of the bed; made of one or two 100 foot lengths of hose; any size attack hose can be used
Term
Skid Load finish
Definition
folding the last three lengths into a compact bundle on the top of the rest of the hose load
Term
Preconnected hoselines
Definition
connected to the discharge valve and placed in an area other than the main hose bed; generally range from 50 to 250 ft in length
Term
Preconnected flat load
Definition
adaptable for varying widths of hose bed and is often used in traverse beds

preconnected, and loops are provided to aid in pulling the load from the bed (number of loops equals how much hose you want)
Term
Triple layer load
Definition
load begins with hose folded in three layers, laid in an 'S' shape; meant to be pulled by one person

whole load must be removed before deploying nozzle

prefered for 2 or 2 1/2 which is too cumbersome for shoulder loads
Term
Minuteman load
Definition
designed to be pulled and advanced by one person; carried on the shoulder completely clear of the ground; pays off the shoulder as the firefighter advances

best for narrow hose beds
Term
Booster hose reels
Definition
rubber-lined hose that are usually carried preconnected and wrapped in coils
Term
Guidelines for laying hose
Definition
do not ride in standing position when apparatus is moving

drive NO GREATER than 5-10 mph

lay the hose to one side of the roadway, but not the gutter, so other vehicles can move around
Term
Forward lay
Definition
hose is laid from the source to the fire (usually source is a hydrant

pumper can remain at the incident

second pumper may need to boost the pressure in the line at the hydrant; one member is temporarily unavailable while at the hydrant
Term
Reverse lay
Definition
hose is laid from the fire or the water source

pumper must first go to the fire location so a size-up can be made before laying the line; effective if pumper needs to stay close to the source

effectively sets up drafting operations

essential equipment must be removed and placed before pumper can leave

common for first pumper to go to the scene, use the water in it's tank, and second pumper goes to the source with a reverse lay
Term
Hard intake marked 'FOR VACUUM USE ONLY'
Definition
do NOT use for hydrant connections; this is for drafting operations only
Term
Split lay
Definition
hose lay deployed by two pumpers, one making a forward lay and one making a reverse lay to the same point
Term
Hoseline in a stairwell
Definition
laid towards the outside wall of the stairwell
