Introduction
This comprehensive examination assesses mastery of NFPA 70E, Standard for
Electrical Safety in the Workplace. It evaluates the knowledge and skills required to
identify electrical hazards, perform risk assessments, select appropriate personal
protective equipment, and implement safe work practices in real-world environments.
The exam employs multiple-choice and scenario-based questions to test both
theoretical understanding and practical decision-making. Emphasis is placed on
applying the hierarchy of risk controls, establishing electrically safe work conditions,
and interpreting regulatory requirements that align with OSHA standards. This
assessment prepares candidates to make sound safety judgments in electrical work
environments.
SECTION ONE: QUESTIONS 1–50
Question 1
,Which of the following best describes the primary purpose of NFPA 70E?
A. To provide electrical installation requirements for commercial buildings
B. To establish safety-related work practices that protect employees from electrical
hazards
C. To regulate utility company transmission and distribution systems
D. To specify manufacturing standards for electrical equipment
🟢 Correct Answer: B. To establish safety-related work practices that protect
employees from electrical hazards
🔴 Explanation: NFPA 70E is the Standard for Electrical Safety in the Workplace. Its
purpose is to provide a practical safe working area for employees relative to the
hazards arising from the use of electricity. It is not an installation code like NFPA 70
(NEC) and does not regulate utility transmission systems.
Question 2
According to NFPA 70E, which document relationship correctly describes OSHA's
use of the standard?
A. OSHA directly enforces NFPA 70E citations
B. NFPA 70E is a law that supersedes OSHA regulations
C. OSHA looks to NFPA 70E to fulfill performance-based requirements in its
standards
D. NFPA 70E has no relationship with OSHA standards
🟢 Correct Answer: C. OSHA looks to NFPA 70E to fulfill performance-based
requirements in its standards
🔴 Explanation: OSHA is the law, and NFPA 70E outlines ways to comply with
OSHA's electrical safety requirements. OSHA may use NFPA 70E as a reference to
support citations for violations related to electrical hazards. The relationship is
,symbiotic, with NFPA 70E providing the how-to for OSHA's performance-based
rules.
Question 3
A qualified electrical worker is performing voltage testing on a 480V panelboard.
What is the minimum approach boundary within which only qualified persons may
enter?
A. Arc flash boundary
B. Limited approach boundary
C. Restricted approach boundary
D. Prohibited approach boundary
🟢 Correct Answer: B. Limited approach boundary
🔴 Explanation: The limited approach boundary is the shock protection boundary
within which only qualified persons are permitted, unless escorted by a qualified
person. The restricted approach boundary is closer and requires additional shock
protection PPE. The prohibited approach boundary was removed in recent editions.
Question 4
What is the arc flash boundary defined as in NFPA 70E Article 100?
A. The distance at which incident energy equals 1.2 cal/cm²
B. The distance at which voltage drops below 50 volts
C. The distance requiring Category 1 PPE
D. The distance from exposed live parts where shock hazard exists
🟢 Correct Answer: A. The distance at which incident energy equals 1.2 cal/cm²
🔴 Explanation: The arc flash boundary is an approach limit from an arc source at
which incident energy equals 1.2 cal/cm² (5 J/cm²). This value represents the
threshold for the onset of a second-degree burn on unprotected skin.
, Question 5
According to the hierarchy of risk controls emphasized in NFPA 70E, which control
method is considered the most effective?
A. Personal protective equipment
B. Administrative controls
C. Elimination
D. Awareness training
🟢 Correct Answer: C. Elimination
🔴 Explanation: The hierarchy of risk controls prioritizes hazard elimination as the
most effective control method, followed by substitution, engineering controls,
awareness, administrative controls, and finally PPE as the last line of defense.
Question 6
An employer must establish, document, and implement a policy for which of the
following?
A. Arc flash incident energy calculations
B. Electrically safe work condition
C. Equipment maintenance schedules
D. Contractor insurance requirements
🟢 Correct Answer: B. Electrically safe work condition
🔴 Explanation: NFPA 70E 110.2(A) requires that an employer establish, document,
and implement an electrically safe work condition policy. This is a fundamental
requirement of the electrical safety program.
Question 7
What is the limited approach boundary for a 480-volt exposed fixed circuit part?
