ISA Utility SpecialistAccident - ANSdiscredited term for unplanned, undesirable event that could result in
unintentional injury/property damage attributed to fate/bad luck
Accident Pyramid - ANSillustration 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 - ANSaccounting methodology that records revenues & costs when they
occur
ACSR - ANSaluminum conductor steel reinforced
Action Threshold - ANSpoint at which the level of incompatible plant species, density, height,
location, condition threatens the stated management objectives & requires implementation of
control method
Active Listening - ANSstructured face to face communication technique that improves
performance & increases understanding btwn people
-use persons name
-paraphrase their message
Acute Toxicity - ANSadverse effects resulting from exposure to a single dose or exposure to
multiple doses of a substance over short time frame
Aerial Application - ANSVM application of herbicide using aircraft(helicopters/fixed wing)
Aerial LIft - ANStruck, logging skidder or vehicle mounted w hydraulic boom supported bucket or
semi-enclosed working platform used to elevate workers
AHAS Inhibitors - ANSchemical 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 - ANSmanually 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 - ANSability of some plants including certain grasses, to release chems that
suppress other plant species growing around them
,ALS Inhibitors - ANSchemical class of commonly used IVM herbicides in which the mode of
action inhibits a key enzyme
-acetolactate synthase
Alternating Current(AC) - ANSelectric current that reverses its direction many times per second
at regular intervals typically used in power supplies
Aluminum Conductor Steel-Reinforced Cable(ACSR) - ANSenergize 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) - ANSmeasure 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) - ANSAmerican National Standard for Tree Care
Operations----Tree/Shrub/Wood Plant Maintenance
-IVM---utility ROW
ANSI Z133 - ANSANSI Arboricultural Operations----Safety Reqs
-safety standard of practice for tree care
Approach Distance - ANSminimum 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 - ANScircuit 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 - ANSplant 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 - ANSclass 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 - ANSelectric flow in an unintended direction thru a process whereby de-energized
lines become energized from an external source----home generator
Bargaining Unit - ANSgroup of workers rep by a union local
Basal Application - ANSherbicide application made at the bottom 12 in of stem & root collar with
an herbicide in an oil carrier
Behavior-Based - ANStheory of industrial accident prevention pioneered by Herbert Heinrich
that considers the overwhelming majority of incidents to be caused by unsafe acts
Biological Methods - ANSmanagement 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 - ANSsection 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 - ANSraised 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 - ANSarea 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 - ANSpruning 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 - ANSpoint where a branch originates from the trunk or another branch
Brand - ANSname/service/trademark/color or attribute that distinguishes a prod or service from
competitors
Brush Cutter - ANSmachine used to remove & grind saplings, small trees, incompatible
vegetation
Budget - ANSmeans to justify the allocation of resources, set priorities & make decisions
regarding what can/can't be accomplished
Bus Work - ANSrigid conductor----usually rectangular or hollow tube design
Business Continuity - ANSability of an org to maintain essential function during & after disaster
