IFSTA 16 Intro to Aerials Flashcards
what are 3 types of aerials
aerial ladder
elevating platform
water tower
define aerial ladder
simply ladder mounted on truck chassis, tiller
most common
define elevating plate form
could be aerial, telescoping or articulating
permanent attached platform installed on end of aerial for personal to operate
what are the 4 main components of a hydraulic system
actuator
fluid
pump
resevoir
to what pressure may hydraulic fluid be under
3500 psi
define hoist cylinder
lifts aerial from the bed
define trunnion
pivoting end of the piston rod connected to anchor ear by heel pin
normally hydraulic pressure is in what ranges
800-3000 psi
how is the working height of an aerial ladder measured
from ground to highest ladder rung at max elevation & extension
what are 3 types of elevating plate forms
aerial ladder
telescoping
articulating
define aerial ladder platform
power operated ladder with device at end
The working height is measured from the ground to the top surface of the handrail on the platform
define telescoping aerial platform
has piping systems and nozzles
not meant for routine egress, only emergencies
What is the required minimum floor area of an aerial platform
14 sq ft
What is required height of a kick plate on Ariel platforms
4”
NFPA 1901 requires the nozzle providing a protective water fog curtain to the bottom of the platform to flow at least how many GPM
75
Elevating platforms 110 feet or shorter should be able to be raised from the bedded position to max elevation Max extension and rotated 90° in how many seconds
150 seconds
True or false, elevating platforms that are taller than 110 feet in length have no time requirement to be elevated extended in rotated 90°
true
Define water tower
Aerial device intended for deploying elevator master stream not generally intended for climbing operations
the 3rd 4th and 5th sections of an aerial are generally extended and retracted by what
cables and pulley
what are 3 types of pre piped aerial ladder waterway’s
bed ladders system
telescoping system
pinnable telescoping system
generally the minimum internal diameter of a telescoping waterway is what
4”
True or false NFPA 1901 requires aerial devices to be equipped with breathing air systems
false
How often should electrical power cords be examined by the driver operator
Daily for damage the insulation in connections
what length hose from a hydraulic pump may produce negative effects on the operation of a tool
100’
At a minimum driver operators of Ariel devices should perform basic inspection/maintenance on which 7 systems of the aerial
Cable hydraulic slides and rollers stabilizing safety breathing air communication
What two purposes does an operation inspection of the aerial serve
Ensure proper working condition
review of Ariel device operation for driver operator
What are two types of tests for Ariel apparatus
Preservice test and service tests
