what is a main difference between a tower ladder and a ladder tower
page 6
Tower ladder has a narrow Ariel ladder capable of emergency egress
ladder tower has a wide walkway that can be used ascending and descending for victim removal operations

page 9
Opposite the first arriving truck or at the next best strategic position
Who decides where to position apparatus based on many variables
page 11

when multiple locations are identified for victim removal position the turntable where
page 12
To reach as many of locations as possible
optimally towers should be able to place their bucket where with respect to proper positioning
page 13
Towers should be able to place the bucket on the ground at or below grade in front of the fire building

20
25,000 or 35psi
first due truck on a high-rise should park on side Alpha unless what
26
Fire location to be readily verified on another side of the building
SLICERS
size up locate fire Identify flow path Cool space Extinguish the fire Rescue Salvage
what two actions Of slicers are considered actions of opportunity and can be employed at any time
Rescue
Salvage
define strategy
32
General plan a course of action decided upon to reach the objectives
L.I.P. is an Anacronym used to define factors which influence strategy
Life safety
Incident stabilization
Property conservation
define tactics
32
Operations that accomplish the incident priorities and support the strategy that the incident commander has the find to mitigate the incident
This is based on slicers
define tasks
32
Jobs performed to accomplish the tactics
truck crew includes; search and rescue VEIS coordinated vent laddering force entry utility control overhaul salvage master stream
exterior crew responsibilities include what
34
horizontal/vertical ventilation placement of portable ladders
What three things should a aerial operator consider when on an incident of a known fire
34
Is this a defensive fire in which master stream preparation is a priority
are crews searching directly over a fire and require ladder placement to the windows
is there a victim on the balcony
What must be evaluated before overhaul begins
39
Condition instability of the structure
if Assessment of structural stability determines high risk involved in manual overhaul what should be considered
Hydraulic and mechanical overall
sprinkler activation may create——-regardless of the size of the fire resulting in obscured vision and toxic gases

define conventional wood roof dimenensions
42
2 x 6 or larger
define lightweight roof construction
42
Trusses the driving strength from compression intention consisting of triangles arranged in a single plan that load applied at the points of intersection of the members
Common material 2 x 3 or 2 x 4 should one fail likely entire truss will fail as well as each trust system after that
members should not be on the roof of a structure where fire is suspected or confirmed in the truss area without being ——
43
Independently supporting
what three factors determine the amount of time a roof can be considered structurally strong
43
What is the type of construction and its condition

Just a note
if they use a picture of an A frame Gable style roof, the difference between type three and type five dimensional lumber is
type five will have a mouth cut and wall stud
Multiple section laminated arches roofing system is subject to failure ——- than the one piece laminated arch
