ISA Utility Specialist NEWEST VERSION WITH
COMPLETE QUESTIONS AND CORRECT DETAILED
ANSWERS \VERIFIED 100% ALREADY GRADED A+
Aerial Application
VM application of herbicide using aircraft(helicopters/fixed wing)
Aerial LIft
truck, logging skidder or vehicle mounted w hydraulic boom supported
bucket or semi-enclosed working platform used to elevate workers
AHAS Inhibitors
chemical class of commonly IVM herbicides in which the mode of action
inhibits key botanical enzyme
-acetohdroxycacid synthase(AHAS) biosynthesis of critical amino acids
Airbrake Switch
manually operated switch deployed where two circuits meet or circuit
portion
from an energized feeder
-not designed to auto interrupt electrical load or be used as line protection
from overload, short circuit or fault
,Allelopathy
ability of some plants including certain grasses, to release chems that
suppress other plant species growing around them
ALS Inhibitors
chemical class of commonly used IVM herbicides in which the mode of
action inhibits a key enzyme
-acetolactate synthase
Alternating Current(AC)
electric current that reverses its direction many times per second at
regular intervals typically used in power supplies
Aluminum Conductor Steel-Reinforced Cable(ACSR)
energize cable constructed from aluminum wire stranded around a steel
core
-lightweight, low cost
-tendency to stretch when heated high electrical load or high temp
-to minimize stretch/add strength steel core is added
Ampere(amp, A)
measure of current
- 1 A = charge carried by 6.25 x 10^18 electrons moving past a given point in
one second
,-ANSI A300(Part 7)
American National Standard for Tree Care Operations Tree/Shrub/Wood
Plant
Maintenance
-IVM - utility ROW
ANSI Z133
ANSI Arboricultural Operations Safety Reqs
-safety standard of practice for tree care
Approach Distance
minimum distance that must be kept btwn conductors/energized
equipment & qualified line clearance personnel & non-qualified &
bodies/tools
-approach distance vary w qualifications of personnel & voltages
Automatic Line Recloser
circuit breaker equipped w mechanism that auto close the breaker after
it has been opened due to a. fault
-designed to reset quickly to give the cause of a fault opp to clear
-may immediately recharge the circuit several times at adjustable time
delay---
-2/3 operations within seconds before they open permanently
, Auxin
plant growth regulator or substance that promotes/influences the growth
& development of plants
-produced at sites where cells are dividing primarily in the shoot tips
-auxin like compounds may be produced synthetically
Auxin Transport Inhibitors
class of selective herbicides that disrupt auxin transport
-auxin transport obstruction causes unnatural concentration of auxin in
meristematic shoots & roots, disturbing the auxin tolerances req for
normal plant growth
Back Feed
electric flow in an unintended direction thru a process whereby de-
energized lines become energized from an external source
----------------------------------------------------------------------home generator
Bargaining Unit
group of workers rep by a union local
Basal Application
herbicide application made at the bottom 12 in of stem & root collar with
an herbicide in an oil carrier
