Steamer hydrant
Dry-barrel hydrant
Wet-barrel hydrant
Gate-valved hydrant
A spanner wrench is designed to:
A. tighten or loosen coupling connections.
B. control the flow of water through a hoseline.
C. fit over most standard hydrant operating nuts.
D. remove discharge caps from fire hydrant outlets.
Mobile water supply operations, such as water shuttles or relay pumping, must be performed:
if hydrant testing is not up-to-date.
when hydrant connections are too difficult to make.
in rural areas without public water distribution systems.
in metropolitan areas that have a high rate of public water consumption.
Which hose deployment tool is used to protect the hose when it is dragged over sharp corners, such as a windowsill?
Hose rope
Hose strap
Hose roller
Hose bridge
Which type of valve device is used to divide one hoseline into two or more hoselines?
Gate valve
Water thief
Wye appliance
Siamese appliance
Which type of hose fitting is used to attach a smaller hose to the end of a larger hose? (601)
Reducer
Hose clamp
Hose bridge
Butterfly valve
In which operation would the pumping apparatus start at the fire scene and lay a supply line back to the water source?
Reverse lay
Forward lay
Standpipe connection
Mobile relay operation
What is one advantage of the minuteman load?
The hose does not drag on the ground.
It requires the use of an adapter or reducer.
It is the most effective deployment method for LDH hose.
It puts less weight on the shoulders of the firefighters carrying the hose.
When advancing a hoseline into a structure, firefighters should:
A. stand on opposite sides of the hose to best stabilize it.
B. keep the entry door chocked open to ensure fast entry.
C. always use an uncharged line, since it weighs much less.
D. first open the nozzle fully and check for adequate water flow.
In order to prevent obstructions when advancing a charged hoseline down a stairway, excess hose should be:
rolled and stored for later use.
stretched outside the stairway.
moved to the right side of the stairwell.
stretched to the opening of the fire compartment.
Water extinguishes fire by:
vaporizing into steam.
reducing the amount of available oxygen.
absorbing heat and cooling the burning material.
interrupting the chemical chain reaction necessary for combustion.
Which type of nozzle has a straight, smooth tip and produces a solid stream of water?
Fog nozzle
Cellar nozzle
Smooth bore nozzle
Straight stream nozzle
Which is a characteristic of fog streams?
Can be adjusted to suit the situation
Longer reach than solid or straight stream
Created by cellar nozzles or piercing nozzles
Less affected by wind than solid or straight streams
A nozzle operator can control the _____ by cradling the hoseline under one arm and evenly distributing his or her weight on both feet while operating the nozzle.
flow rate
friction loss
water hammer
nozzle reaction
Friction loss causes:
the nozzle to be difficult to control.
damage to the hose lining and couplings.
reduced water flow and pressure at the nozzle.
a water pressure surge that can damage the hose.
Master stream devices are usually deployed when:
the fire is below ground level.
there is an increased risk of flashover.
a structure is more than six stories tall.
the fire is too large to be controlled by handlines.
Which type of hose appliance is used to combine two separate hoselines into one?
Wye appliance
Water thief
Gate valve
Siamese appliance
What is the primary purpose of a hose clamp during fireground operations?
To connect two hoses of different diameters
To increase water pressure at the nozzle
To stop the flow of water in a hoseline
To protect the hose from sharp objects
Which nozzle setting produces the greatest surface area of water for absorbing heat?
Solid stream
Broken stream
Straight stream
Fog pattern
What is the main function of a hose roller during fireground operations?
To connect two hoses together
To increase water pressure
To store hoses after use
To prevent hose kinks at corners
Which type of hose appliance allows water to be taken from a main line without interrupting the flow?
Reducer
Siamese appliance
Water thief
Wye appliance
What is the primary reason for using a fog nozzle during interior fire attack?
To combine multiple hoselines into one
To absorb heat efficiently by increasing water surface area
To minimize water damage
To reach fires at a greater distance
