Introduction
This comprehensive examination is designed to assess a candidate's mastery of the
NFPA 70E Standard for Electrical Safety in the Workplace. It rigorously evaluates
theoretical knowledge, practical application, and critical decision-making skills
necessary to identify, evaluate, and control electrical hazards. The assessment
employs a variety of multiple-choice questions, including scenario-based problems
that reflect real-world situations. Successful candidates will demonstrate a deep
understanding of risk assessment procedures, the proper selection and use of
personal protective equipment, and the implementation of safe work practices to
prevent injury and ensure regulatory compliance. This test bank serves as both a
learning tool and a benchmark for professional readiness.
SECTION ONE: QUESTIONS 1-50
,1. Which of the following is the primary goal of performing an arc flash risk
assessment as defined by NFPA 70E?
A. To determine the type of Personal Protective Equipment (PPE) required for all
tasks.
B. To identify hazards and estimate the likelihood of occurrence of injury or
damage to health.
C. To calculate the exact incident energy for every piece of equipment in a facility.
D. To comply with all OSHA regulations without exception.
🟢 Correct Answer: B. To identify hazards and estimate the likelihood of
occurrence of injury or damage to health.
🔴 Explanation: An arc flash risk assessment is a process to identify hazards and
estimate the potential for injury. While it can inform PPE selection (A), its core is
broader. Calculation (C) is part of incident energy analysis, not the primary goal.
Compliance (D) is a secondary benefit.
2. According to NFPA 70E, an electrically safe work condition is established
when all of the following conditions are met EXCEPT:
A. Equipment is disconnected from all energy sources.
B. A lockout/tagout procedure is applied.
C. A test for the absence of voltage is performed.
D. The equipment is determined to be in a "de-energized" state by a qualified
person.
🟢 Correct Answer: D. The equipment is determined to be in a "de-energized"
state by a qualified person.
🔴 Explanation: The establishment of an electrically safe work condition requires
the equipment to be tested for the absence of voltage (C) after it has been
,disconnected (A) and locked out (B). Simply being deemed "de-energized" by a
person is not sufficient; it must be verified through the formal six-step process.
3. The "limited approach boundary" is the distance from an exposed energized
electrical conductor or circuit part within which:
A. An arc flash could cause a second-degree burn.
B. A shock hazard exists and unqualified persons must be escorted.
C. The incident energy is calculated at 1.2 cal/cm².
D. Only qualified persons are permitted, and they must wear arc-rated PPE.
🟢 Correct Answer: B. A shock hazard exists and unqualified persons must be
escorted.
🔴 Explanation: The limited approach boundary is a shock protection boundary.
Unqualified persons can enter if escorted by a qualified person. The arc flash
boundary is where incident energy is 1.2 cal/cm² (C), and the restricted approach
boundary requires specific training and PPE for shock (not arc, D).
4. An arc flash hazard analysis is used to determine which of the following?
A. The shock protection boundaries for a task.
B. The incident energy level to which an employee could be exposed.
C. The minimum approach distance for a person.
D. The voltage level of the equipment in question.
🟢 Correct Answer: B. The incident energy level to which an employee could be
exposed.
🔴 Explanation: The specific purpose of an arc flash hazard analysis is to
determine the incident energy. This is then used to select the appropriate Arc-
Rated PPE. Shock protection boundaries are determined by voltage (A), and
approach distances are related to shock (C).
, 5. Which type of PPE is designed to extinguish arc flash energy and protect the
head from impact and heat?
A. Arc-rated face shield.
B. Arc-rated balaclava.
C. Arc-rated hard hat.
D. Arc-rated hood (with face shield).
🟢 Correct Answer: D. Arc-rated hood (with face shield).
🔴 Explanation: An arc-rated hood provides 360-degree head and face
protection, integrating a face shield. A face shield (A) alone doesn't protect the
back or top of the head. A balaclava (B) protects the head but not the face from
impact. A hard hat (C) must be arc-rated to be effective against arc flash, but the
hood is the comprehensive solution.
6. An employee is troubleshooting a 480V motor control center (MCC) that is
considered "live." The task requires the employee to open a panel door to
perform a voltage test. What is the FIRST step the employee should take?
A. Don the appropriate arc-rated PPE.
B. Complete a Job Safety Plan (JSA) / Job Hazard Analysis (JHA).
C. Perform a risk assessment for the specific task.
D. Verify the absence of voltage.
🟢 Correct Answer: C. Perform a risk assessment for the specific task.
🔴 Explanation: NFPA 70E mandates that a risk assessment is performed before
any work is started. This assessment considers the task, hazards, and potential
risks to determine the need for PPE and other controls. While donning PPE and
completing a JHA are part of the process, they follow the initial risk assessment.
7. The term "arc flash" is best defined as:
