-
Buffer Zone
-
Warm Zone
-
Hot Zone
Pregunta 2
Pregunta
What is minimum square feet aerial platform must be?
Respuesta
-
12 feet
-
14 feet
-
16 feet
-
18 feet
Pregunta 3
Pregunta
Which staging would be implemented when numerous units are responding to operate at the same incident, particularly those that require mutual aid or result in transmittal of multiple alarms?
Respuesta
-
Level I
-
Primary
-
Secondary
-
Level II
Pregunta 4
Pregunta
If fire conditions are evident upon arrival, what is the best option for positioning?
Respuesta
-
Place the apparatus as physically close to the scene as possible
-
Place the apparatus at the first available position that offers a view of the incident scene
-
Place the apparatus in a safe position that offers the best tactical advantage
-
Place the apparatus in a position that is in the middle of the incident scene for easy access
Pregunta 5
Pregunta
If fire conditions are not evident upon arrival, which is the best option for positioning the fire apparatus?
Respuesta
-
Drive the apparatus all the way around the building.
-
Pull the apparatus directly in front of the building.
-
Stop the apparatus well before approaching the building.
-
Pull the apparatus past the front of the building.
Pregunta 6
Pregunta
Which of the following is an item tiller operators must be particularly aware of?
Respuesta
-
Distance of the trailer from the base of the building involved
-
Keeping one hand on the wheel and one on the radio
-
Under-correcting
-
Keeping the trailer in a turn
Pregunta 7
Pregunta
Because a large amount of heat is required to change water to steam:
Respuesta
-
the fire will be extinguished before water changes to steam.
-
this allows less heat to be absorbed from the fire.
-
this allows more heat to be absorbed from the fire
-
the fire will expand before water puts it out
Pregunta 8
Pregunta
Which principle of friction loss demonstrates the advantage of a larger size hose?
Respuesta
-
When hoses are the same size, friction loss varies approx with the square of the increase in velocity of the flow
-
For the same discharge, friction loss varies inversely as the fifth power of the diameter of the hose
-
If all other conditions are the same, friction loss varies directly with the length of the hose
-
For a given velocity, friction loss is approx the same, regardless of the pressure on the water
Pregunta 9
Pregunta
Which of the following is the best option when arriving on scene and no fire is evident
Respuesta
-
Pull apparatus past the front of the building
-
Stop the apparatus well before approaching the building
-
Pull the apparatus directly in front of the building
-
Drive the apparatus all the way around the building and back
Pregunta 10
Pregunta
When determining routes to take, drivers should plot routes that avoid
Respuesta
-
Residential housing areas
-
Four-way intersections
-
Cloverleaf intersections
-
Low overpasses
Pregunta 11
Pregunta
Which statement about the ability of water to extinguish fire is most accurate
Respuesta
-
Water must be combined with some other extinguishing agent in order to extinguish fires
-
Water breaks the chain reaction of a fire by disrupting the fuel source
-
Water extinguishes fire by cooling the object it's applied to
-
Water can cool or absorb heat from a fire as well as smother fire
Pregunta 12
Pregunta
Atmospheric pressure at sea level is:
Respuesta
-
16.4 psi
-
14.7 psi
-
12.2 psi
-
10.0 psi
Pregunta 13
Pregunta

Respuesta
-
Level I Staging
-
Primary Staging
-
Level II Staging
-
Secondary Staging
Pregunta 14
Pregunta
In which of the following situations would tandem pumping most likely be used?
Respuesta
-
When first engine is more than 5 years old
-
When additional personnel are requested at the scene
-
When it's necessary to supply a high rise sprinkler or standpipe
-
When a single engine is capable of supplying required pressure
Pregunta 15
Pregunta
An automatic fog nozzle is designed to
Respuesta
-
change patterns while maintaining the same nozzle pressure
-
provide a relatively low volume of water delivery.
-
allow the firefighter operating the handline to select flow rate to suit the fire and operating conditions.
-
flow a specific volume of water on all stream patterns at a specific nozzle discharge pressure.
Pregunta 16
Pregunta
A constant flow fog nozzle is designed to:
Respuesta
-
provide a relatively low volume of water delivery.
-
change patterns while also changing nozzle pressure.
-
flow a specific volume of water on all stream patterns at a specific nozzle discharge pressure.
-
allow the firefighter operating the handline to select flow rate to suit the fire and operating conditions.
Pregunta 17
Pregunta
What should be done if priming has not been achieved within the acceptable time period for a particular situation?
Respuesta
-
Priming should continue until a prime is achieved
-
Priming attempt should be stopped and the problem traced
-
Wait 5-10 minutes and try priming again
-
Mutual aid resources called to the scene

-
improve the overall stability of the apparatus.
-
