Chapter 16 Flashcards
(30 cards)
A method of loading hose on a vehicle that results in hoes appearance that resembles accordion sections. This is achieved by standing the hose on it edge and laying it side to side in the hose bad
Accordion hose load
The delivery of water from an attack engine to a headline, which discharges the water onto the fire
Attack line operations
A nozzle with a tip that can be separated from the shut off valve
Breakaway nozzle
Delivery of water from a water supply source such as a fire hydrant or a static water source, to an attack engine
Supply Line operations
Starts at the hydrant and proceeds toward the fire
Forward hose lay
Method of laying a supply line where the supply line starts at the attack engine and ends at the water source
Reverse hose lay
A specialized type of valve that can be placed on a hydrant and that allows another engine to increase the supply pressure without interrupting flow.
four way hydrant valve
A scenario in which the attack engine forward lays a supply line from an intersection to the fire, and the supply engine reverse lays a supply line from the hose left by the attack engine to the water source.
Split hose lay
A method of putting a hose on a vehicle in which the hose is laid flat and stacked on of top the previous section.
Flat hose load
A method of loading hose in which the hose is laid into the bed along the three walls of the bed, so that it resembles a horseshoe.
Horseshoe hose load
A hose bed arranged to enable the engine to lay out either a single supply line or two supply lines simultaneously.
Split hose bed
A hose loading method used when one long hose line is needed ; the end of the last length of a hose in one bed of a split hose bed is coupled to the beginning of the first length of hose in the opposite bed
Combination hose load
What features describes a dry standpipe system?
1.) The supply line is connected to the discharge side of the pump
2.) It is used for attack lines operated inside the building.
3.) The fire department has to provide all of the water
A hose and nozzle that can be held and directed by hand.
Handline
Hose loading method that allows a single firefighter to flake out the necessary amount of hose from the shoulder while advancing toward the fire, this load avoids having to maneuver the hose lines around obstacles and helps prevent sharp kinks
Minuteman hose load
Hose loading method similar to the flat hose load used for supply lines, except the female end of the hose is pre connected to a pump discharge outlet, and a nozzle is attached to the male end of the hose line
Preconnected flat hose load
A hose load method in which the hose is folded back onto itself to reduce the overall length to one-third before loading the into the bed. This load method reduces deployment distances
Triple layer hose load
Order to carry out a preconnected flat hose load?
1.) Attach the female end to the discharge outlet.
2.)Begin flat loading the hose in the hose bed.
3.) Make a loop, or ear, on the second or higher fold.
4.) Attach the nozzle to the male coupling at the end.
Friction Points
Places where a hoseline encounters resistance, such as corners, doorways and stairs.
In what sequence would you perform these steps to add additional lengths of hose with a breakaway type nozzle?
1.) Close the valve to stop the flow of water.
2.) Remove the nozzle tip.
3.) Attach the extra hose to the shut-off valve.
4.) Install the nozzle tip on the male end of the added hose.
If you want to lay two parallel lines in a forward hose lay, you will need to use a ____________ hose. (measured length)
2 1/2 in (65mm)
If you are loading hose with threaded couplings using the accordion hose load, and you place the male hose coupling in the rear of the hose bed first, you are preparing for a _________.
(tip: ______ hose lay)
Forward hose lay
When an engine is located at a fire hydrant, the most common technique is to attach _________ to the suction side of the pump on the attack engine.
A large diameter soft sleeve hose
To advance an accordion load using a shoulder carry, you need to ________.
Twist the fold so they become flat
