ISA UTILITY SPECIALIST QUESTIONS AND ANSWERS
Accident - Answers- discredited term for unplanned, undesirable event that could result
in unintentional injury/property damage attributed to fate/bad luck
Accident Pyramid - Answers- 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 - Answers- accounting methodology that records revenues & costs
when they occur
ACSR - Answers- aluminum conductor steel reinforced
Action Threshold - Answers- 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 - Answers- structured face to face communication technique that
improves performance & increases understanding btwn people
-use persons name
-paraphrase their message
Acute Toxicity - Answers- adverse effects resulting from exposure to a single dose or
exposure to multiple doses of a substance over short time frame
synthase(AHAS)----biosynthesis of critical amino acids
Airbrake Switch - Answers- 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 - Answers- ability of some plants including certain grasses, to release
chems that suppress other plant species growing around them
ALS Inhibitors - Answers- chemical class of commonly used IVM herbicides in which
the mode of action inhibits a key enzyme
-acetolactate synthase
Alternating Current(AC) - Answers- electric current that reverses its direction many
times per second at regular intervals typically used in power supplies
Aluminum Conductor Steel-Reinforced Cable(ACSR) - Answers- 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
Aerial Application - Answers- VM application of herbicide using aircraft(helicopters/fixed
wing)
Aerial LIft - Answers- truck, logging skidder or vehicle mounted w hydraulic boom
supported bucket or semi-enclosed working platform used to elevate workers
AHAS Inhibitors - Answers- chemical class of commonly IVM herbicides in which the
mode of action inhibits key botanical enzyme
-acetohdroxycacid
Ampere(amp, A) - Answers- 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) - Answers- American National Standard for Tree Care Operations---
-Tree/Shrub/Wood Plant Maintenance
-IVM---utility ROW
ANSI Z133 - Answers- ANSI Arboricultural Operations----Safety Reqs
-safety standard of practice for tree care
Approach Distance - Answers- 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 - Answers- 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 - Answers- 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 - Answers- 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 - Answers- electric flow in an unintended direction thru a process whereby
de-energized lines become energized from an external source----home generator
Bargaining Unit - Answers- group of workers rep by a union local
Basal Application - Answers- herbicide application made at the bottom 12 in of stem &
root collar with an herbicide in an oil carrier
Behavior-Based - Answers- theory of industrial accident prevention pioneered by
Herbert Heinrich that considers the overwhelming majority of incidents to be caused by
unsafe acts
Biological Methods - Answers- management of vegetation by establishment & control of
compatible stable plant communities using plant competition, allelopathy, animals,
insects, pathogens
-cover-type conversion is a type of biological control
Border Zone - Answers- section of a transmission/pipeline ROW that extends from
wire/pipe zone to the ROW edge
-managed to promote a low growing plant community of forms, tall shrubs & low
growing trees below a specified height(25 ft)
Branch Bark Ridge - Answers- raised strip of bark at the top of a branch union where
the growth & expansion of trunk + parent stem & adjoining branch push the bark into the
ridge
Branch Collar - Answers- area where a subdominant branch joins another branch or
trunk that is created by overlapping vascular tissue from both the branch & trunk
-typically enlarged at the base of the branch
Branch Removal Cut - Answers- pruning cut the removes the smaller of two branches
at a union or parent stem, w/o cutting into the branch bark ridge or branch collar or
leaving stub
Branch Union - Answers- point where a branch originates from the trunk or another
branch
Brand - Answers- name/service/trademark/color or attribute that distinguishes a prod or
service from competitors
Brush Cutter - Answers- machine used to remove & grind saplings, small trees,
incompatible vegetation
Budget - Answers- means to justify the allocation of resources, set priorities & make
decisions regarding what can/can't be accomplished
