WITH QUESTIONS AND CORRECT VERIFIED ANSWERS
GRADED A+ GUARANTEED 100% PASS
Accident - CORRECT ANSWERS-discredited term for unplanned, undesirable event that could
result in unintentional injury/property damage attributed to fate/bad luck
Accident Pyramid - CORRECT 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
High-Voltage Lines - CORRECT ANSWERS-lines w voltages greater than 750 V
Hotspotting - CORRECT ANSWERS-limited tree work is schedules on a specific are of the
network where shorts/outages are occurring
Hurricane - CORRECT ANSWERS-regional term for Western Hemisphere tropical cyclones w
wind speeds 74 mph+
Hydration - CORRECT ANSWERS-condition of having adequate fluid in body tissues
Hydroelectric - CORRECT ANSWERS-electric generation using water
Allelopathy - CORRECT ANSWERS-ability of some plants including certain grasses, to release
chems that suppress other plant species growing around them
ALS Inhibitors - CORRECT ANSWERS-chemical class of commonly used IVM herbicides in
which the mode of action inhibits a key enzyme
-acetolactate synthase
,Alternating Current(AC) - CORRECT 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) - CORRECT 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
Ampere(amp, A) - CORRECT 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) - CORRECT ANSWERS-American National Standard for Tree Care
Operations----Tree/Shrub/Wood Plant Maintenance
-IVM---utility ROW
ANSI Z133 - CORRECT ANSWERS-ANSI Arboricultural Operations----Safety Reqs
-safety standard of practice for tree care
Approach Distance - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWERS-electric flow in an unintended direction thru a process
whereby de-energized lines become energized from an external source----home generator
Bargaining Unit - CORRECT ANSWERS-group of workers rep by a union local
Basal Application - CORRECT ANSWERS-herbicide application made at the bottom 12 in of
stem & root collar with an herbicide in an oil carrier
Behavior-Based - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWERS-point where a branch originates from the trunk or
another branch
Brand - CORRECT ANSWERS-name/service/trademark/color or attribute that distinguishes a
prod or service from competitors
Brush Cutter - CORRECT ANSWERS-machine used to remove & grind saplings, small trees,
incompatible vegetation
Budget - CORRECT ANSWERS-means to justify the allocation of resources, set priorities &
make decisions regarding what can/can't be accomplished
Bus Work - CORRECT ANSWERS-rigid conductor----usually rectangular or hollow tube design
Business Continuity - CORRECT ANSWERS-ability of an org to maintain essential function
during & after disaster
Capacitor - CORRECT ANSWERS-electrical device used to correct power factors
-temporarily stores charge of electricity & returns it to restore a line balance
Capacitive Reactance - CORRECT ANSWERS-charge that builds up btwn long parallel
conductors
-portion of load slighly impedes current
