Ch 4. Positioning Apparatus Flashcards
When fire conditions are evident upon arrival, the driver/operator should place the apparatus in a safe position that includes what?
In a safe position that includes an exit route
When may the 1st arriving apparatus consider pulling past the front of the building when responding?
At an incident where no fire is present
When a pumper is responding to an incident, what is always the first tactical priority?
Life safety (Rescue)
Where should the first arriving engines lay supply lines:
Where they are accessible to later arriving apparatus
What may help reduce the possibility of the apparatus becoming an exposure?
Position the apparatus up wind of the incident
At what type of incident should an apparatus and personnel be downhill of the main body of fire?
Wildland fires
When responding to a roadway incident, what lanes should be closed?
The lane of the road where firefighters are operating as well as an additional lane for a safety zone
Why should supply hose be laid to the side of the street before being charged?
Large diameter hose is almost impossible to move once charged with water
Where is generally considered the safest position should a building collapse?
Corners of a structure
What is one likely indication of impending building collapse?
Bulging walls
Where should a pumper position at the incident scene to allow for Aerial placement?
Pumpers must yield in optimum position close to a building for Ariel apparatus
The inside/outside method of apparatus placement in which attack pumpers are positioned on the side of the street closest to the building and Ariel Apparatus are placed outboard of pumpers is used when:
The building is less than five floors tall
What factors should pumpers consider when supplying an Aerial apparatus for elevated master streams?
Friction loss due to distance and elevation
The location for positioning to support fire department connections is best determined during what planning phase?
Through pre-incident planning
When positioning an apparatus for drafting, preference should be given to a location that has what type of road surface?
A location accessible from a hard surface
When involved in drafting operations, any personal working near the edge of bodies of water are required to:
Where a personal flotation device
Which is a preferred type of hose for hydrant connections?
Large diameter intake hose
What is one way to help prevent kinks when attaching supply line to a hydrant?
Make several counter clockwise twists prior to connecting the hose. This twist does not restrict water flow or cause kinks
When opening hydrants, it is advantageous to stand:
Behind the hydrant
Generally, in tandem pumping operations, one strong hydrant is used to supply to pumpers because:
They are both being used as attack pumpers at the same incident
Tandem pumping operations involve a form of relay pumping with pumpers positioned:
Close together rather than evenly spaced in the supply hose layout. Tandem pumping is used to increase discharge pressures
What type of incident would most likely involve tandem pumping operations?
Supplying a high-rise sprinkler or standpipe system
How far apart can pumpers be positioned when tandem pumping?
Apparatus may be located up to 300 feet apart
Tandem pumping is generally used at an incident to:
Increase water pressure
