NFPA 70E FINAL EXAM: 2026/2027
EDITION
SECTION 1: GENERAL REQUIREMENTS & THE ELECTRICAL
SAFETY PROGRAM
Question 1: What is the primary purpose of NFPA 70E?
A) To provide installation requirements for electrical equipment (NEC)
B) To protect personnel from electrical hazards in the workplace
C) To establish electrical equipment testing standards
D) To define electrical licensing requirements
Answer: B
Rationale: NFPA 70E is the "Standard for Electrical Safety in the
Workplace." Its sole focus is protecting workers from the major
electrical hazards of shock, electrocution, arc flash, and arc blast,
distinguishing it from installation standards like the NEC .
Question 2: According to NFPA 70E 2024, what is the first and most
effective priority in the hierarchy of risk controls?
A) Personal Protective Equipment (PPE)
B) Engineering controls
C) Elimination
D) Administrative controls
,Answer: C
Rationale: The hierarchy of risk controls mandates that elimination
(i.e., de-energizing) is the highest level of protection. The 2024 edition
strengthened requirements to document this hierarchy, ensuring that
PPE is the last line of defense, not the first .
Question 3: How often must NFPA 70E be updated according to its
revision cycle?
A) Every year
B) Every 3 years
C) Every 5 years
D) Every 10 years
Answer: B
Rationale: NFPA 70E follows a three-year revision cycle. The 2024
edition was released in late 2023, and the next edition is scheduled for
2027 .
Question 4: Who is ultimately responsible for establishing and
implementing an electrical safety program?
A) The qualified electrical worker
B) The safety manager
C) The employer
D) The equipment manufacturer
Answer: C
Rationale: NFPA 70E places the legal and financial responsibility for
establishing, documenting, and implementing the electrical safety
program squarely on the employer .
,Question 5: What is the general voltage threshold at which NFPA 70E
electrical safety requirements typically apply?
A) 30 volts
B) 50 volts
C) 120 volts
D) 240 volts
Answer: B
Rationale: NFPA 70E applies to systems operating at 50 volts or more.
This threshold aligns with OSHA regulations, recognizing that voltages
below this level generally do not present a significant arc flash or
shock hazard under normal conditions .
Question 6: Which of the following is NOT one of the primary
electrical hazards addressed by NFPA 70E?
A) Electric shock
B) Arc flash
C) Electromagnetic radiation
D) Arc blast
Answer: C
Rationale: The standard specifically addresses electric shock
(electrocution), arc flash (thermal burn), and arc blast (pressure wave).
While the 2024 edition defines radiation, electromagnetic radiation is
not a primary focus for workplace electrical safety practices .
Question 7: What must be documented when performing a risk
assessment according to the 2024 edition?
A) Only the PPE requirements
B) The hierarchy of risk controls applied for each task
, C) The equipment manufacturer
D) The worker's experience level
Answer: B
Rationale: A key update in the 2024 edition is the explicit
requirement to document the hierarchy of risk controls applied
(Elimination, Substitution, Engineering, Awareness, Administrative,
PPE) for each specific task .
Question 8: What is the maximum interval for retraining employees on
electrical safety-related work practices?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
Answer: C
Rationale: Retraining must occur at intervals not exceeding three
years. However, more frequent retraining is required if observations or
changes in job assignments indicate the employee is not retaining the
knowledge .
Question 9: Which of the following is an acceptable justification for
performing energized electrical work?
A) It is more convenient to work energized
B) De-energizing would introduce additional or increased hazards
C) The worker prefers to work energized
D) The equipment has never failed before
Answer: B
Rationale: Energized work is only permitted if de-energizing
