CH3 Flashcards
(25 cards)
When positioning for exposure protection, consider the apparatus as a
potential exposure
pg 125
If handlines or portable master streams are to be used, the pumper must be positioned in
Close proximity to the structure or incident to allow an effective water supply.
Structures built with lightweight materials and buildings with faux facades, parapets, or cantilevers can also suffer
Rapid collapse
pg 126
Structures that are ___, ____, or _____ may pose a higher risk even before a fire or other catastrophe.
Old, poorly maintained, or under construction
pg 127
Depending on the incident, apparatus equipment, and personnel operating within ____ of the base of a high-rise fire may need to be protected from falling glass and debris.
200ft
pg 128
If a structure is fewer than 5 floors tall, the attack pumper is positioned on the
side of the street closest to the structure and aerial apparatus are placed outboard of the pumper.
pg 128
When the fire structure is 5 floors or more, the attack pumper takes the outside position to allow the aerial apparatus
Maximum reach
pg 128
To effectively supply an FDC, the D/O should position the pumper as close as possible to the water
Source
pg 129
Drafting operations are required when a pumper must be supplied from a static water supply source such as a
Dry hydrant, cistern, storage tanks, lake, or stream
pg 131
Preference should be given to drafting locations accessible from a
hard surface that require a minimum length of hard intake hose or lift.
pg 131
____ consist of an intake hose connection on the shore and a length of pipe extended into the water with a strainer on the end.
A dry hydrant
pg 132
One hydrant that has sufficient capacity to maintain the minimum residual pressure for the total fire flow is used to supply two pumpers.
Dual pumping
pg 134
____ pumping operations are a form of relay pumping with the pumpers positioned close together in the supply hose layout.
Tandem
pg 134
Tandem pumping may be needed when pressures higher than a single engine is capable of supplying are required, and also when it is necessary to supply a
high-rise or standpipe system
pg 134
In ____ pumping operations, apparatus may be positioned up to 300ft apart.
Tandem
pg 134
If the first-arriving unit has no immediate orders for later-arriving apparatus, the officer may call for _____ staging to be implemented while the incident is investigated.
Level I
pg 135
In Level II staging, one or more apparatus staging areas may be designated by the
Operations Section Chief, from which the IC can draw additional resources.
pg 135
_____ may be expanded or contracted with the changing dynamics of the incident.
Control zones
pg 136
Also called the restricted zone, exclusion zone, or red zone.
Hot zone
pg 136
The ____ zone, also called the limited access zone or yellow zone.
Warm zone
pg 136
____ is used to provide support for operations in the hot zone and to decontaminate personnel and equipment exiting the hot zone.
Warm zone
pg 136
Also called the support zone or green zone.
Cold zone
pg 136
Apparatus and personnel should be ___ of the main body of the fire as wildland fires move ____ faster than on flat terrain or downhill.
downhill; uphill
pg 139
Responders must consider all railroad tracks to be
“Live” (active)
pg 142
