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
