◉ The 2004 edition of NFPA 70E introduced the requirements of ? .
The 2021 edition ? all previous editions. Answer: D. the energized
electrical work permit / supersedes
◉ NFPA 70E Chapter 1 applies generally to electrical safety in the
workplace. Chapter 2 addresses safety-related ? requirements.
Chapter 3 ? Chapter 1 with safety requirements for special
equipment. Answer: B. Maintenance / supplements or modifies
,◉ Explanatory material is included in the form of informational
notes, which are not enforceable as requirements. Brackets
containing section references to another NFPA document are for
informational purposes only and are provided as a guide to indicate
the source of the extracted text. Answer: True
◉ An arc flash hazard is defined in Article 100 as a source of
possible injury or damage to health associated with the release of
energy caused by an electric arc. Informational Note No. 1 indicates
that the likelihood of occurrence of an arc flash incident increases
when energized electrical conductors or circuit parts are exposed or
when they are within equipment in a(n) ? condition, provided a
person is interacting with the equipment in such a manner that
could cause an electric arc. An arc flash incident is not likely to occur
under normal operating conditions when enclosed energized
equipment has been properly installed and ? . Answer: D. Guarded or
enclosed / maintained
◉ Arc rating is defined in Article 100, in part, as the value attributed
to materials that describes their performance with exposure to an
electrical arc discharge and is expressed ? . Informational Note No. 1
states, in part, that arc-rated clothing or equipment has been tested
for exposure to an electric arc and that flame-resistant (FR) clothing
without an arc rating ? been tested for exposure to an electric arc.
Answer: c. in cal/cm2 / has not
,◉ ATPV is defined in ASTM F1959/F1959M as the incident energy
(cal/cm2) on a material or a multilayer system of materials that
results in a ? probability that sufficient heat transfer through the
tested specimen is predicted to cause the onset of a second degree
skin burn injury based on the Stoll curve. EBT is defined in ASTM
F1959/F1959M as the incident energy (cal/cm2) on a material or a
material system that results in a ? probability of breakopen. Answer:
C. 50% /50%
◉ The Informational Note to the definition of arc flash boundary
(Boundary, Arc Flash) states that, according to the Stoll skin burn
injury model, the onset of a second degree burn on unprotected skin
is likely to occur at an exposure of ? for ? second(s). Answer: a. 1.2
cal/cm
◉ A. An approach limit at a distance from an exposed energized
electrical conductor or circuit part within which a shock hazard
exists
B. An approach limit at a distance from an exposed energized
electrical conductor or circuit part within which a shock hazard
exists
C. When an arc flash hazard exists, an approach limit from an arc
source at which incident energy equals 1.2 cal/cm2 (5 J/cm2)
Answer: A. Limited Approach Boundary
B. Restricted Approach Boundary
C. Arc Flash Boundary
, ◉ An electrical hazard is defined as a dangerous condition such that
contact or ? can result in electric shock, arc flash burn, thermal burn,
or ? . Answer: B. Equipment failure / arc blast injury
◉ Incident energy is defined as the amount of thermal energy
impressed on a surface, a certain distance from the source,
generated during an electrical arc event. Incident energy is typically
expressed in ? . Answer: B. Calories per centimeter squared
(cal/cm2)
◉ A qualified person is defined as one who has demonstrated skills
and knowledge related to the construction and ? of electrical
equipment and installations and has received safety training to ? the
hazards and reduce the associated risk. Answer: D. Operation /
identify
◉ An unqualified person is defined as a person who is not a
qualified person. Answer: True
◉ The requirements that address host and contract employer's
responsibilities require a number of things. Which of the following
are among those requirements? Answer: D. I, IV, and V
