Chpt 11 Flashcards
This includes the water in the apparatus mounted water tank. This supply has a limited amount of water and must be supplemented by another source before it runs out
Internal water source
This includes water from a hydrant or another pump
Pressurize source
The most common pressurized source is the
Hydrant
This includes water sources such as a lake, stream, pool, or water tank.
Static source
The driver operator must be capable of transferring water from an internal water tank supply to an external source, a practice referred to as a
Changeover operation
When approaching the scene, you as a driver operator should position the fire apparatus according to your fire department policies and procedures and turn the front wheels toward the curb on a
45 degree angle
Newer fire apparatus have features that automatically change emergency lighting to ______ this is a feature that you would use when operating at the scene of the emergency
On scene mode
When you are content with placement of the fire apparatus, the first procedure that you must perform is placing the transmission into ____, based on the fire apparatus
Neutral or park
Once the pump is engaged, your first task upon existing the of the fire apparatus is to _____ the wheels of the fire apparatus
Chock
Once the fire pump is engaged, the driver/operator is ready to supply the attack lines for firefighting operations using the _____ as a water supply
Internal water tank
Usually the _____ is used only to fight small fires, such as vehicle fires, dumpster fires, small brush fires, and other nuisance fires and also to start the initial fire attack until a large water source can be obtained
Internal water tank
Are standard methods of working with fire hose to accomplish different objectives in a variety of situations
Fire hose evolutions
Involve laying hoselines and making connections between a water supply source and an attack pumper
Supply line operations
Involve advancing hose lines from an attack pumper to apply water onto the fire
Attack line operations
The objective of laying a _____ is to deliver water from a hydrant or an alternative water source to an attack pumper
Supply line
A _____ starts at the hydrant and proceeds toward the fire in this case the hose is laid in the same direction as the water flows from the hydrant to the fire
Forward lay
Involves laying the hose from the fire to the hydrant with this evolution the hose is laid in the opposite direction to the water flow
Reverse lay
The ____ is most often used by the first arriving engine company at the scene of the fire
Forward hose lay
The _____ allows the engine company to establish a water supply without the assistance from an additional company
Forward hose lay
Some departments use a ______ to connect the supply line to the hydrant, thereby ensuring that the supply line can be charged with water immediately, yet still allowing for a supply engine to connect to the line later.
Four way hydrant valve
This operation can be accomplished without uncoupling any lines or interrupting the flow.
Four way hydrant
In the ____ the hose is laid from the fire to the hydrant, in the direction opposite to the flow of water
Reverse hose lay
The _____ may be a standard tactic in areas where sufficient hydrants are available and additional companies that can assist in establishing a water supply will arrive quickly
Reverse hose lay
Is performed by two engine companies in situations where hose must be laid in two different directions to establish a water supply
Split hose lay
This evolution could be used when the attack pumper must approach a fire either along a dead end street with no hydrant or down a long drive way
Split hose lay
As a driver operator securing a _____ upon your crews arrival on the scene is one of your primary responsibilities
Water source
In this kind of ____, you position the engine close to the fire scene and deploy the supply hose from the bed of the fire apparatus to the hydrant either yourself or with very little assistance from other fire fighters
Hand lay
If you use LDH in your fire department, it is common practice to carry short lengths of LDH for the purpose of making a connection between the fire apparatus intake and the hydrant. These lengths of hose generally range from 15 to 25 ft and have names such as _________
Soft suction hose or pony lines
If you carry LDH, it is most often available in _____ lengths
100ft
If you anticipate that additional water may be needed, place an appliance such as a _____ on the dry barrel hydrant prior to opening the hydrant
Gated ball valve
Are used to provide a water supply for attack lines that will be operated inside a building
Standpipe systems
The pressure requirements for standpipe systems depend on the _____ at which the water will be used inside the building
Height
Unless more specific information is available, sprinkler systems should generally be fed at a pressure of
150 psi
Due to certain building characteristics within a response area as well as the height and construction materials used in the building, _______ may be present in a fire building
Private fire protection systems
The fire department connection can be either _______
Free standing or wall mounted
Each female connection should have a ______ inside the Siamese connection that will swing to the closed position on the connection that is not in use.
Clapper valve
Depending on the fire departments SOP, it is generally recommended that both or all connections to the FDC be used when supplying a
Standpipe
A ______has water under pressure in the pipe at all times it is typically supplied by the water utility department having jurisdiction
Wet system
In contrast, a ______ has no water in the pipe and depends on the fire department to supply the water
Dry system
