ISA UTILITY SPECIALIST ACTUAL TEST
PAPER 2026 COMPLETE QUESTIONS AND
SOLUTIONS GRADED A+
●● Accident Pyramid.
Answer: illustration of Herbert Heinrich principles of accident
prevention-----bottom has thousands of unsafe acts/conditions, led to
300 close calls, 29 minor injuries & ultimately one major fatality/injury
at top
●● Accrual Accounting.
Answer: accounting methodology that records revenues & costs when
they occur
●● ACSR.
Answer: aluminum conductor steel reinforced
●● Action Threshold.
Answer: point at which the level of incompatible plant species, density,
height, location, condition threatens the stated management objectives &
requires implementation of control method
●● Active Listening.
,Answer: structured face to face communication technique that improves
performance & increases understanding btwn people
-use persons name
-paraphrase their message
●● Acute Toxicity.
Answer: adverse effects resulting from exposure to a single dose or
exposure to multiple doses of a substance over short time frame
●● Aerial Application.
Answer: VM application of herbicide using aircraft(helicopters/fixed
wing)
●● Aerial LIft.
Answer: truck, logging skidder or vehicle mounted w hydraulic boom
supported bucket or semi-enclosed working platform used to elevate
workers
●● AHAS Inhibitors.
Answer: 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.
Answer: 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.
Answer: ability of some plants including certain grasses, to release
chems that suppress other plant species growing around them
●● ALS Inhibitors.
Answer: chemical class of commonly used IVM herbicides in which the
mode of action inhibits a key enzyme
-acetolactate synthase
●● Alternating Current(AC).
Answer: electric current that reverses its direction many times per
second at regular intervals typically used in power supplies
●● Aluminum Conductor Steel-Reinforced Cable(ACSR).
Answer: 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).
Answer: 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).
Answer: American National Standard for Tree Care Operations----
Tree/Shrub/Wood Plant Maintenance
-IVM---utility ROW
●● ANSI Z133.
Answer: ANSI Arboricultural Operations----Safety Reqs
-safety standard of practice for tree care
●● Approach Distance.
Answer: 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.
