Chapter # 5 Positioning Apparatus Flashcards
What is one exception to the rule of positioning apparatus uphill?
In wildland fires position down hill due to rapid fire spread uphill.
Name 9 positioning considerations when fire conditions are evident.
Department SOP’s. Rescue Situations. Method of Attack. Water Supply. Exposures. Wind Directions. Terrain. Relocation Potential. Building collapse.
Name signs of building collapse or a unstable building.
Bulging walls. Large cracks in the exterior; falling brick, block or mortar; interior collapse.
If it is not possible to relocate from falling debris, what should be done?
Cover the apparatus with salvage covers.
Where should a pumper position on a building less then 5 stories in height?
On the inside/building side of the street.
What tool other then rope or floats can be used to keep a intake hose off the bottom of the water source?
A ground ladder.
To what degree should the front wheels of a apparatus be turned to facilitate easy readjustment of a apparatus when connecting to a hydrant?
45 degrees
When connecting to a hydrant with a side intake engine, where should the engine stop.
Just short of the hydrant to facilitate a curve in the hose.
Soft intake hose that does not have sexless couplings can have two twist put into before connecting to the pumper. What does this do?
Prevents kinks.
When using a front or rear intake connection where should the pumper be aimed?
In the direction of the hydrant at a 45 degree angle or less.
What is one of the easiest ways to ensure the maximum possible flow?
Removing kinks
When both small diameter and large diameter hydrant connections are going to be used; what hose should receive preference in relation to apparatus position?
The large diameter.
One strong hydrant is used to supply two pumpers.
Dual pumping
A form of relay pumping but with the pumpers positioned close together.
Tandem pumping
In tandem pumping apparatus may be apart up to how many feet?
300’
What are the two most common functions of wildland fire apparatus?
Structure protection. Direct fire attack.
When positioning a wildland apparatus, do not position them next to or under these 4 things.
Power lines. Trees or snags. LPG tanks or other pressurized vessels. Structures that might burn.
Wild land crews always begin their fire attack from what?
A anchor point.
What should be done when there is reduced visability when driving a wildland apparatus?
Decrease speed. Use a spotter.
Spotters should do these three things.
Have a reliable hand light. Wear highly visible clothing. Stay in the drivers field of view at all times.
What should be done to the wildland apparatus if it is positioned for a stationary operation?
Pull and charge a 1 1/2” or 1 3/4” line for protection. Chock the wheels. Face the exit direction.
If wildland apparatus must be driven into where crews are working what should be done.
Use horn/siren intermittently, drive slowly, use warning lights.
Personal assigned to them are commonly used as extra manpower or to perform truck functions when one is not present.
