1. What is the primary purpose of NFPA 70E?
A. To establish electrical equipment manufacturing standards
B. To provide electrical safety-related work practices for
employee protection
C. To replace all OSHA regulations
D. To establish utility electricity rates
Answer: B. To provide electrical safety-related work practices
for employee protection
Rationale: NFPA 70E focuses on practical electrical safety-
related work practices, maintenance requirements, and
administrative controls intended to protect workers from
electrical hazards.
2. Which of the following is a major electrical hazard
addressed by NFPA 70E?
A. Arc flash
B. Noise from office equipment only
C. Slips on dry floors only
D. Poor handwriting
,Answer: A. Arc flash
Rationale: Arc flash is a significant electrical hazard that can
cause severe burns, blindness, hearing damage, and other
injuries.
3. What is the preferred condition for performing electrical
work?
A. Energized work
B. Electrically safe work condition
C. Work without PPE
D. Work during a storm
Answer: B. Electrically safe work condition
Rationale: NFPA 70E emphasizes establishing an electrically
safe work condition whenever possible rather than working on
energized equipment.
4. Which hazard involves current passing through a person's
body?
A. Arc blast
B. Electric shock
C. Thermal radiation only
D. Mechanical vibration
,Answer: B. Electric shock
Rationale: Electric shock occurs when the body becomes part
of an electrical circuit and current flows through it.
5. What can an arc flash produce?
A. Heat and intense light
B. Only cold air
C. Only magnetic fields
D. No physical effects
Answer: A. Heat and intense light
Rationale: An arc flash can release enormous thermal energy
and intense light, potentially causing severe burns and eye
injuries.
6. What is an electrically safe work condition?
A. Equipment that appears to be switched off
B. A condition in which electrical conductors and circuit parts
have been disconnected, locked/tagged, tested, and
appropriately secured
C. Equipment operating at reduced voltage
D. Equipment with a warning label
Answer: B. A condition in which electrical conductors and
circuit parts have been disconnected, locked/tagged, tested,
and appropriately secured
, Rationale: Simply turning equipment off does not establish an
electrically safe work condition.
7. Which procedure is commonly used to control hazardous
electrical energy?
A. Lockout/tagout
B. Painting
C. Lubrication
D. Ventilation
Answer: A. Lockout/tagout
Rationale: Lockout/tagout controls hazardous energy and helps
prevent unexpected energization or startup.
8. Why must absence of voltage be verified?
A. To save electricity
B. Because equipment that appears de-energized may still be
energized
C. To improve lighting
D. To reduce paperwork
Answer: B. Because equipment that appears de-energized may
still be energized
Rationale: Verification is essential because incorrect
identification, backfeed, stored energy, or other sources can
leave conductors energized.
