1. According to NFPA 70E, the primary goal of an Electrical Safety
Program is to:
A) Ensure productivity targets are met
B) Provide practical, safe working conditions for employees relative to
electrical hazards
C) Reduce workers' compensation insurance costs
D) Comply with local building codes only
Answer: B. NFPA 70E Article 110.1 states that the electrical safety
program shall identify the principles on which it is based and provide
direction for its implementation to achieve the goal of providing an
electrically safe working condition and protecting employees from
electrical hazards.
2. The principle that protective measures must be prioritized from
most effective to least effective is known as the:
A) Risk Assessment Matrix
B) Hierarchy of Risk Controls
C) PDCA Cycle
D) Safety Management System
Answer: B. The Hierarchy of Risk Controls is outlined in NFPA 70E
Section 110.1(H). The order is: Elimination, Substitution, Engineering
Controls, Awareness, Administrative Controls, and Personal Protective
Equipment (PPE).
,3. Who is responsible for conducting a risk assessment before a
task is performed?
A) The Safety Manager
B) The Facility Owner
C) The Qualified Person performing the task
D) The Human Resources Department
Answer: C. NFPA 70E Section 110.1(A) states that the risk assessment
shall be performed by a "qualified person" who is trained to identify
hazards and assess the associated risk.
4. An "Electrically Safe Work Condition" (ESWC) is defined as:
A) When the equipment doors are closed and latched
B) When the voltage is below 50 volts
C) When conductors are disconnected from energized parts,
locked/tagged, tested, and grounded if necessary
D) When a safety observer is present
*Answer: C. This definition is found in Article 100 and detailed in
Article 120. It requires the complete de-energization, verification (live-
dead-live), and lockout/tagout of the source.*
5. If a task requires crossing the Restricted Approach Boundary,
what must be in place?
A) A fire watch
B) An Energized Electrical Work Permit (EEWP)
C) A job safety plan signed by a supervisor
D) Double-insulated tools only
Answer: B. Section 130.2(B) requires an Energized Electrical Work Permit
when work is performed within the Restricted Approach Boundary or
when the task increases the likelihood of an arc flash.
6. NFPA 70E requires that the Electrical Safety Program be
reviewed at intervals not to exceed:
A) 6 months
,B) 1 year
C) 3 years
D) 5 years
Answer: C. Section 110.1(I) requires the program to be reviewed for
effectiveness at intervals not exceeding three years.
7. A "Qualified Person" is defined as one who:
A) Has a Master Electrician license
B) Has worked in the field for more than 10 years
C) Has demonstrated skills and knowledge related to the construction
and operation of equipment and the hazards involved
D) Is appointed by the CEO
Answer: C. NFPA 70E Article 100 defines a qualified person as one who
has demonstrated skills and knowledge related to the construction and
operation of electrical equipment and installations and has received
safety training to recognize and avoid the hazards involved.
8. A job briefing is required to be held before the start of each
job. If the work is repetitive and similar, the briefing must be
held:
A) Daily
B) Weekly
C) Monthly
D) Annually
Answer: A. Section 110.2(A)(3) states that if the work is repetitive and
similar, the briefing must be held daily.
9. The hierarchy of risk controls places the highest priority on:
A) Personal Protective Equipment
B) Engineering Controls
C) Elimination (de-energization)
D) Training
, Answer: C. Elimination—physically removing the hazard—is the most
effective control method.
10. For the purpose of establishing an ESWC, what is the final step
before beginning work?
A) Opening the disconnecting device
B) Applying lockout/tagout devices
C) Verifying the absence of voltage (Live-Dead-Live)
D) Visually verifying the disconnect is open
*Answer: C. Article 120 outlines the steps; verifying the absence of
voltage with a properly rated tester is the final safety confirmation that
the circuit is de-energized.*
Questions 51-100: Risk Assessment and Boundaries
11. The combination of the likelihood of occurrence of injury or
damage to health and the severity of injury or damage to health
that results from a hazard is defined as:
A) Hazard
B) Danger
C) Risk
D) Exposure
Answer: C. Section 100 defines "Risk" specifically as the combination of
likelihood and severity .
12. The distance from an arc source at which the incident energy
equals 1.2 cal/cm² is known as the:
A) Restricted Approach Boundary
B) Limited Approach Boundary
C) Arc Flash Boundary
