NFPA 70E Electrical Safety in the Workplace:
Verified Questions and Answers | Instant PDF
Study Guide
1. What is the primary purpose of NFPA 70E?
A. To establish electrical equipment manufacturing standards
B. To provide requirements for safe electrical work practices
and protect workers from electrical hazards
C. To replace the National Electrical Code (NFPA 70)
D. To regulate utility electricity pricing
Answer: B. To provide requirements for safe electrical work
practices and protect workers from electrical hazards
Rationale: NFPA 70E focuses on electrical safety in the
workplace. Its purpose is to help employers and employees
identify electrical hazards and establish safe work practices,
boundaries, personal protective equipment (PPE), planning
requirements, and other controls intended to reduce the risk of
shock, electrocution, arc flash, and arc-blast injuries.
2. Which of the following is considered an electrical hazard
under NFPA 70E?
,A. Noise only
B. Electrical shock only
C. Arc flash only
D. Electrical shock, arc flash, and arc blast
Answer: D. Electrical shock, arc flash, and arc blast
Rationale: Electrical work can expose employees to several
related hazards. Shock occurs when a person becomes part of
an electrical circuit. An arc flash is a dangerous release of
energy through an electrical arc, while an arc blast involves
pressure and other physical effects associated with an arc event.
A proper electrical safety program considers all applicable
hazards rather than focusing exclusively on shock.
3. Before a worker begins electrical work, what should be
determined first?
A. The color of the worker's PPE
B. Whether the worker has worked on similar equipment before
C. Whether an electrically safe work condition can be
established and whether energized work is justified if it
cannot
D. Whether the equipment is more than five years old
,Answer: C. Whether an electrically safe work condition can be
established and whether energized work is justified if it
cannot
Rationale: NFPA 70E places strong emphasis on establishing an
electrically safe work condition whenever possible. Energized
electrical conductors and circuit parts should generally be
placed into an electrically safe work condition before employees
work on or near them. If energized work is being considered, the
applicable justification and planning requirements must be
addressed.
4. What does an electrically safe work condition generally
mean?
A. Equipment is switched off from a control panel
B. Equipment appears to be operating normally
C. Electrical conductors and circuit parts have been
disconnected, locked/tagged as required, verified de-
energized, and properly grounded where applicable
D. A supervisor has verbally stated that the equipment is safe
Answer: C. Electrical conductors and circuit parts have been
disconnected, locked/tagged as required, verified de-
energized, and properly grounded where applicable
, Rationale: Simply turning equipment off does not necessarily
create an electrically safe work condition. The process includes
identifying the circuit, disconnecting it from sources, applying
lockout/tagout controls, releasing stored electrical energy,
verifying absence of voltage with properly rated test equipment,
and addressing other potential sources of energy. The exact
procedure must follow the applicable NFPA 70E requirements
and employer procedures.
5. What is the purpose of establishing an electrically safe work
condition?
A. To reduce equipment maintenance costs
B. To prevent employees from being exposed to electrical
hazards while performing the work
C. To eliminate the need for training
D. To eliminate all PPE requirements in the facility
Answer: B. To prevent employees from being exposed to
electrical hazards while performing the work
Rationale: De-energization is one of the most effective ways to
eliminate electrical hazards. When conductors and circuit parts
are properly placed in an electrically safe work condition, the
worker is not normally exposed to the same energized electrical
hazards that would exist during energized work. However, the
