Ch. 5: Positioning Apparatus Flashcards
(97 cards)
How should each type of apparatus be positioned according to?
Its purpose and its role in achieving strategic goals and tactical objectives.
What is the primary function of a fire department pumper on the fireground?
To provide water for firefighting operations.
Determining the proper positioning for the attack pumper begins with:
sizing up the incident.
Where is an apparatus generally advisable to stop when arriving at a location where no fire is evident (investigation mode)?
Near the best access point into the occupancy, often the main entrance.
What is the first tactical priority at any fire incident?
life safety
How will there be less strain on the fire pump when supplying hoselines?
Pumping hoselines downhill, rather than uphill
When is the only exception where the uphill rule of positioning?
wildland fires; position downhill because first move uphill faster
What is generally the safest positioning of the apparatus should a collapse occur?
At the corners of the building
What is considered an optimum position for aerial apparatus?
corners of the building
What will indicate that reinforcement ties are present to support weak or unstable walls?
presence of ornamental stars or bolts
What can indicate a high collapse potential?
ornamental stars
When buildings are higher than five stories, where should aerial apparatus be positioned?
Next to the building, Engines on the outside position
What operations are required when a pumper is going to be supplied from a static water supply?
drafting operations
Where should the pumper stop, when placing the intake hose directly into the static water source for drafting?
Before reaching the source.
What consists of an intake hose connection on the shore and a length of pipe equipped with a strainer that extends into the water supply source?
dry hydrant
What is the most common water supply source in many jurisdictions?
fire hydrant
What is the preferred type of hose for connection to a fire hydrant?
large diameter intake hose (soft sleeve/soft suction)
What is the main disadvantage of connecting to the 2 1/2” outlet of a fire hydrant?
It limits the amount of water that can be supplied.
What operations are actually a form of relay pumping with the pumpers positioned close together rather than evenly spaced in the supply hose layout?
tandem pumping
Because of the dynamic nature of wildland fires,
wildland fire apparatus are seldom positioned in the same location for the duration of the incident.
What are the two most common functions of wildland fire apparatus?
Providing structural protection and making a direct attack on the fire.
What is the highest priority for most wildland firefighting operations after life safety?
The protection of structures that are exposed to the fire.
How should engines be positioned for safety in wildland fires?
backed in from the last known turnaround
Where should engine crew’s wildland attack always begin in order to reduce the risk as much as possible?
From the anchor point - a natural or man-made barrier that will prevent the fire from spreading around and encircling the engine and the crew.
