ISA UTILITY SPECIALIST EXAM ACTUAL EXAM 2026 | ALL QUESTIONS AND CORRECT
ANSWERS | GRADED A+ | VERIFIED ANSWERS | UPDATED VERSION
Question 1
Which document serves as the industry-developed, national consensus safety standard for
arboricultural operations in the United States?
A) OSHA 1910.269
B) ANSI Z133
C) ISO 14001
D) ANSI A300
E) NERC FAC-003
Correct Answer: B) ANSI Z133
Rationale: The ANSI Z133 is the American National Standard for Arboricultural
Operations, establishing the safety requirements that the industry has agreed upon as the
standard of practice. While OSHA provides federal regulations, Z133 is the specific
consensus standard developed by the industry for the industry.
Question 2
What is the term for a physiological reaction caused by the passage of electrical current through
the human body?
A) Electrocution
B) Back Feed
C) Electric Shock
D) Step Potential
E) Induction
Correct Answer: C) Electric Shock
Rationale: Electric shock is the physical reaction to current passing through the body. It is
important to distinguish this from electrocution, which specifically refers to death resulting
from such an electrical passage.
Question 3
Which of the following is considered a "Lagging Indicator" in a safety program?
A) Close calls
B) Unsafe acts
C) Safety committee meetings
D) Fatalities
E) Tool inspections
Correct Answer: D) Fatalities
Rationale: Lagging indicators are metrics that track events that have already occurred,
such as serious injuries or fatalities. Conversely, leading indicators track proactive
measures or minor incidents like unsafe acts and close calls to predict and prevent future
accidents.

Question 4
A worker touches a conductive ladder that is leaned against an energized conductor. This is an
example of:
A) Direct Contact
B) Indirect Contact
C) Step Potential
D) Touch Potential
E) Back Feed
Correct Answer: B) Indirect Contact
Rationale: Indirect contact occurs when someone touches a conductive object (like a ladder,
tool, or branch) that is itself in contact with an energized fixture. Direct contact would
involve the worker physically touching the energized fixture with their own body.
Question 5
Which theory of industrial incident prevention suggests that the overwhelming majority of
incidents are caused by unsafe acts rather than equipment failure?
A) Multiple Causation Theory
B) High-reliability Theory
C) Behavior-based Principles
D) Systems Approach
E) The Pareto Principle
Correct Answer: C) Behavior-based Principles
Rationale: Pioneered by Herbert Heinrich, Behavior-based Principles focus on the human
element, asserting that unsafe acts are the primary cause of workplace accidents. This
differs from Multiple Causation Theory, which looks at the random interaction of various
contributing factors.
Question 6
What term describes death resulting from electric shock?
A) Cardiac Arrest
B) Voltage Differential
C) Electrocution
D) Arc Flash
E) System Failure
Correct Answer: C) Electrocution
Rationale: Electrocution is a portmanteau of "electric" and "execution," and in a safety
context, it is reserved specifically for instances where the electric shock results in a fatality.
Question 7
The distance from energized conductors inside of which qualified line-clearance arborists may
not work, as established by ANSI Z133, is known as:
