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
Materials to make couplings |
|
Definition
brass, aluminum, or magnesium |
|
|
Term
|
Definition
pin, rocker, and recessed; rocker is the most common |
|
|
Term
|
Definition
divides a single hoseline into two or more lines
all wyes have a single female and two male |
|
|
Term
|
Definition
two hoselines going into a single
two female and one male |
|
|
Term
|
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
|
Definition
one LDH inlet and three 2 1/2 valve-controlled male outlets |
|
|
Term
|
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
|
Definition
facilities the connection of hoselines of different diameters and thread types |
|
|
Term
|
Definition
fetting for connecting hose couplings with dissimilar threads and the same diameter (double-male, double-female) |
|
|
Term
|
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
|
Definition
provide support for intake or discharge hose at the pumping apparatus by preventing kinks |
|
|
Term
|
Definition
protects male pump discharge |
|
|
Term
|
Definition
protects FDC female inlets |
|
|
Term
|
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
|
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
|
Definition
stops the flow of water in a hoseline |
|
|
Term
|
Definition
used when vehicles must drive over a hoseline |
|
|
Term
|
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
|
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
|
Definition
creates a compact roll that can be easily transported and carried (eg. highrises) |
|
|
Term
|
Definition
twin donut roll with a built-in carrying loop formed by the hose itself |
|
|
Term
|
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
|
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
|
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
|
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
|
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
|
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
|
Definition
folding the last three lengths into a compact bundle on the top of the rest of the hose load |
|
|
Term
|
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
|
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
|
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
|
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
|
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
|
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
|
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
|
Definition
hose lay deployed by two pumpers, one making a forward lay and one making a reverse lay to the same point |
|
|
Term
|
Definition
laid towards the outside wall of the stairwell |
