When positioning apparatus, the driver/operator should:

Proper placement for numerous situations that may occur are?

2• exposures
3• water supply
4• method of attack
5• Hose lines deployment
7• Wind direction
8• terrain

Driver should position pumpers providing water supply for elevated stream operation as closely to the aerial apparatus as practical because

Friction loss due to distance and elevation are major consideration when supporting elevated streams

In order to supply a fire department connection most efficiently a pumper should position as closely as possible to the water source. this location is best determined through

Pre-incident planning

What is a dry hydrant

A permanently installed pipe that has pumper suction connection installed at static water source to speed drafting operation

Some department have to used hard intake hose to connect a pumper to a hydrant

true

When using the side intake connection to connect to a hydrant. To avoid blocking the street with the Apparatus the driver must

Stop close to the curb with the pump intake a few feet short of being in line with the hydrant

Stopping short of the hydrant also the intake hose to curve slightly,preventing

Kinks that can drastically restrict flow

Tandem pumping the higher pressure is a result of two pumpers acting in

Series

Relay pumping is generally use to increased the _____of water available at a fire scene while tandem pump in (another form of relay) is most often undertaken to increase water _____

VOLUME,PRESSURE

For safety and efficiency,once the apparatus arrive at the structure it is assigned to protect in wild land fire:

Anchor point

A natural or man-made barrier that would prevent the fire from encircling the vehicle and crew

Typical anchor are

Roads,Lakes,ponds,or previously burned areas

Position the apparatus ____on the side of the structure to minimize exposure to heat in blowing embers

LEEWARD

How does the wildland crew ensure complete extinguishment when progressing along the fire edge

By working engines in tandem. Additional personnel and Apparatus may be used to mop up

If the fire is spreading rapidly _____draw engine and crew back to the flanks rather than attempt a frontal attack

Upslope

Do not drive into ____where crew may be operating

Smoke near the location of other crew

Base

Maybe established as an area from which large number of personnel and quantities of equipment may be deployed. This area serves as a primary point outside incident area to which responding units report a receive initial order for action

the driver must exercise care when stepping beyond the protection offered by

The tailboard of a properly place apparatus

Decontamination process usually take place within

The Decon corridor located in the warm zone

The proximity of the exhaust discharge from Park apparatus should be

Considered relative to the location of patient being extricated are treated nearby

Whether responding to an incident along limited access highway, City street, rural Road, or urban/Wildland interface, apparatus must be positioned for

Maximum safety and efficiency

In order to accomplish maximum safety and efficiency a driver/operator must understand the role of the Apparatus and the overall IAP

true

The understanding of the IAP will be based on

* pre-incident planning * knowledge of department policies * Communication from the IC

What is the 1st tactical priority at any incident

LIFE SAFETY

a primary concern of the driver and company officer in the placement of the pumper is

ESTABLISHING WATER SUPPLY

when should a pumper on board tank can be consider for water supply

after a proper size up confirm the location and extent of the fire

one exception to the uphill rule

wild land fire (fire move faster uphill in wild land)

Apparatus may be located up to_______in tandem pumping

300'

relay pumping is generally used to increase _____of water at a fire and tandem is used to increase water______

volume,pressure

the maximum attainable lift is...(a fire engine in fairly good condition can lift 2/3 of the theoretical lift,2/3×33.9

22.5'

for stand pipe evolution,if the pumper is more than 100' from the FDC on a building, an additional _____psi must be added for each 100' of additional hose

FDC consists of a

consists of a clappered siamese with two or more 2.5" intakes or one large diameter( 4") intake

Many jurisdictions installed

Dry hydrant,which should be Flow tested by AHJ to determine their capabilities

Operation where a strong hydrant is used to supply to pumpers by connecting the pumpers intake to intake

Dual pumping

A method used when pressures higher than the capability of a single pump are required

Tandem pumping

For a fully loaded train to make a complete stop may required how many mile

1-2

Apparatus should maintain a clear zone of___From a railroad tracks to prevent contact

30'

the standard for the inspection, care and use of fire hose, couplings and nozzles is

NFPA 1962

the boundary between wildland and structural development is often referred to as the (pg.146)

Wildland urban interface (challenging environment for firefighting operations)

__________ ______ staging is often used on any multiunit response of two or more units, the first arriving vehicles of each type proceed directly to the scene and the others stand by a block from the scene and await orders (Engine by the closest hydrant)

LEVEL 1(pg.150)

MUTCD stands for

manual of uniform traffic control device

MUTCD advises that emergency vehicle warning lights should be used as necessary to reach the incident but once on scene their use should be

Reduced as much as possible

For structures threatened by wild land fires, Engine should be backed in

From the last known turn around, and the crew should note the locations of landmarks along the way

Driver/operator must be well-trained and knowledgeable in local _____ ______in order to efficiently execute any maneuvers the incident commander or the IAP may require

policies and procedure

What situation may require tandem pumping operations

1• When it is necessary to supply a high-rise sprinklers or standpipe 2• where the attack pumper is located relatively short distance from the water source but a great distance from the fire
