1. Which standard primarily governs electrical safety-related work
practices in the United States?
A) NFPA 70E
B) OSHA 1910 Subpart S
C) NEC Article 110
D) IEEE 1584
Answer: A) NFPA 70E
Rationale: NFPA 70E provides comprehensive guidelines for electrical
safety in the workplace, including risk assessments, PPE requirements,
,and safe work practices, while OSHA 1910 enforces regulations but does
not provide detailed work practices.
2. What is the primary purpose of an electrically safe work condition?
A) To minimize electrical energy for operational efficiency
B) To eliminate the risk of electric shock and arc flash injuries
C) To ensure equipment runs at rated voltage
D) To maintain a continuous current flow
Answer: B) To eliminate the risk of electric shock and arc flash injuries
Rationale: Establishing an electrically safe work condition is
fundamental to worker safety, ensuring circuits are de-energized, locked
out, and verified before work begins.
3. Which of the following is a critical step in the Lockout/Tagout
(LOTO) procedure?
A) Disconnecting the neutral conductor only
B) Verifying the absence of voltage before work
C) Notifying OSHA of every lockout
D) Leaving switches in the “on” position
,Answer: B) Verifying the absence of voltage before work
Rationale: Verification ensures the system is fully de-energized, which is
the cornerstone of electrical safety. Simply locking out a device without
verifying voltage is insufficient.
4. What does the arc flash boundary represent?
A) Distance at which shock hazards are negligible
B) Distance at which PPE is required to prevent burns from an arc flash
C) Area where grounding is mandatory
D) Minimum distance for fire extinguisher placement
Answer: B) Distance at which PPE is required to prevent burns from an
arc flash
Rationale: The arc flash boundary defines the area around energized
equipment where the thermal energy of a potential arc flash could
cause second-degree burns; proper PPE is required inside this
boundary.
5. Which PPE is required for protection against arc flash hazards?
A) Rubber gloves only
B) Flame-resistant clothing and face shield
, C) Safety glasses only
D) Steel-toe boots only
Answer: B) Flame-resistant clothing and face shield
Rationale: NFPA 70E specifies flame-resistant clothing, gloves, face
shields, and sometimes hoods as necessary to protect against arc flash
hazards. Eye protection alone is insufficient.
6. What is the minimum voltage at which electrical equipment is
considered hazardous under NFPA 70E?
A) 50 volts AC
B) 120 volts AC
C) 240 volts AC
D) 600 volts AC
Answer: A) 50 volts AC
Rationale: NFPA 70E recognizes that exposure to voltages of 50 volts or
higher AC (or 120 volts DC) can present a shock hazard.
7. What is the purpose of a risk assessment before performing
electrical work?
