. What would you like to do?
What must happen for the incident action plan (IAP) to be implemented efficiently and safely?
Apparatus must be positioned so that its use is maximized and the interference with other units is minimized.
The primary function of a fire department pumper on the fireground is to
provide water for fire fighting operations
To determine the proper position for the attack pumper you must begin with
sizing up the incident
What is the deciding factor when committing/positioning of apparatus on scene?
SOP's and the judgement of the responsible officer or driver/operater
The first arriving pumper usually goes
to the front entrance.
_____ _____ is always the first tactical priority at any fire incident.
If the first-arriving apparatus is located in a position that is difficult for other apparatus to access, such as up a narrow lane or driveway, who deploys the supply hose?
A supply hose should be laid into the scene as the apparatus moves into position.
When considering exposures, it is important to remember
that we bring our own potential exposure with us: the apparatus itself.
True or false Whenever possible, attempt to position the apparatus downwind of the incident.
- Whenever possible, attempt to position the apparatus upwind of the incident.
In most cases, it is desirable to position apparatus uphill from the incident whenever possible because?
There is less strain placed on the fire pump by supplying hoselines downhill rather than pumping uphill.
It is desirable to position apparatus uphill from the incident whenever possible. What is the one exception?
At a wildland fire. Wildland fires move uphill faster than on flat terrain or downhill.
When laying a supply hose into the fire scene what should you consider?
Make sure that the hose is laid to the side of the street if at all possible
The collapse zone is
equal to at least 1 and 1/2 times the height of the building.
Where is the optimum position for aerial apparatus?
At the corners of the building
Lare pieces of glass and other debris may fall from many stories above street level and land as far as ________ _________ from the base of the building.
Avoid positioning the apparatus
under power lines and utility lines.
Why should aerial apparatusbe given the most optimum position over pumping apparatus?
Aerial's have a fixed length but most pumpers have in excess of 1,000 ft (300m) of hose.
What is inside/outside method?
- Buildings less than 5 stories tall, engine companies are on the side of the street closest to the building and aerials are outboard.
- Higher than 5 stories tall, aerials next to the building and engines take the outside position.
In most jurisdictions, the most common water supply source is
a fire hydrant
Proper positioning of apparatus for intake from a hydrant is judged
from the hydrant rather than the curb line because hydrants are located different distances from the curb.
Why should a driver stop the pumper short a few feet of the intake being inline with the hydrant outlet?
Stopping short permits the intake hose to slightly curve, preventing kinks that can drastically restrict flow.
When using front or rear intake connections how should the pumper be positioned?
vehicle should be aimed or angled (45 degrees or less) in the direction of the hydrant
What is the main disadvantage of connecting to a 2 1/2 inch outlet?
it limits the amout of water that can be supplied.
Removing kinks is one of the easiest ways to ensure
maximum possible flow
Large diameter intake is also known as
the steamer or intake header connection
When using multiple intake connections (large and small diameter) positioning should be determined by
the soft sleeve requirements because it is the shorter (and greater capacity) hose.
Dual pumping is often incorrectly referred to as
Tandum pumping may be needed
- when pressures higher than a single engine is capable of supplying are required
- high-rise sprinkler
- standpipe systems
- very long hose lays
To set up for tandem pumping, the two engines may be positioned how far apart?
In tandum pumping higher pressures result from
the fact that the pumps are actually acting in series.
The two most common functions for wildland fire apparatus are
providing structural protection and making a direct attack on the fire
After life safety, the highest priority for most wildland fire fighting operations is
the protection of structures that are exposed to the fire
The boundary between the wildland and structural development is often referred to as
Once the engine reaches the structure it has been assigned to protect, it should be positioned so that it is safe and convenient from which to work by preforming the following procedures:
- -off roadway to avoid blocking evacuting vehicles.
- -scrape away fuel to avoid positioning in flammable vegetation.
- -position on lee side of structure to minimize exposure to heat and blowing embers.
- -position near structure to keep hoselines short (not too close)
- -keep cab doors and windows closed to keep out embers
- -air conditioner on recirculation mode.
- -not near or under...power lines, trees, strutures that might burn, LPG tanks or vessels
Referring to wildland fires, typical anchor points are
- a natural or man-made barrier that prevents fire from spreading around engine and crew.
- burned areas
When apparatus is used in a mobile attack lines should be kept as short as possible because
hoselines are less likely to become looped around stumps or other objects and easier to disentangle
During pump and roll spotters are needed
- nightime driving when terrain is not visible.
- when fuel is higher than the bumper or running boards.
Apparatus attacking from the unburned side should allow for what 2 conditions?
- loss of water
- mechanical failure
If apparatus must be driven through smoke
- sound horn or sire intermittently
- use warning lights and headlights
- drive slow
What apparatus may be present on the fireground in addition to pumping and ariel
- command vehicles
- breathing air supply
Command vehicle should be positioned where?
Near a corner of a building so the the IC is afforded a view of two sides of the building. Good locations are: driveways, parking lots, yards or cross streets
What items are commonly used markers for ICP?
- traffic cones
- flashing lights
What two types of equipment are used to refill SCBA bottles on the scene?
- cascade systems
- breathing air compressors
Where are apparatus using breathing air compressors to refill SCBA cylinders (need on scene of fire) best positioned?
upwind of the fire in clear air space
What two types of EMS vehicles may respond to a fire scene?
- rapid response units (nontransport)
- ambulances (transport)
When responding to a scene you hear a officer call for Level I staging, other responding units should
stop (stage) at least one block away from the scene in their direction of travel and await further orders
What types of incidents require Level II stage?
Incidents that require mutual aid or result in multiple alarms
Companies in staging must be ready to respond within
3 minutes of being called
On roadways where vehicles normally travel at high speeds, apparatus should not be driven against the normal flow of traffic unless
police units have closed the road
On virtually every fire or transportation incident the company officer and driver should consider the possibility
that hazardous materials may be involved
On highway incidents additional apparatus should be positioned how far behind the shielding apparatus to act as an additional barrier?
150 to 200 feet behind
How many lanes of traffic should be closed next to the incident lane?
at least one
Why should apparatus not be stopped over manholes on incident scenes?
Flammable materials flowing into the underground systems could ignite and explode
If at all possible, approach hazardous materials incidents
from the upwind and uphill side
Many departments use a series of ________ ________ to organize the emergency scene.
When responding to repeated bomb threats and other potential terrorist incidents at a given location responders should avoid
always staging in the same place
Hot zone is also called
- restricted zone
- exclusion zone
- red zone
The warm zone is also called
- contamination reduction zone
- limited-access zone
- yellow zone
The cold zone is also called
List indicators that a serious exterior collapse may occur
- bulging walls
- large cracks in the exterior
- falling bricks, blocks or mortar
- interior collapses
The presence of ornamental stars or bolts with large washers at various intervals on exterior walls indicates
weak or unstable walls
What type of operation allows one strong hydrant to supply two pumpers and is rarely used?
Dual pumping operations
