Arc Flash Hazard - CORRECT ANSWER-A dangerous condition associated with the
possible release of energy caused by an electric arc
Arc Rating - CORRECT ANSWER-The value attributed to materials that describes their
performance to exposure to an electrical arc discharge. The arc rating is expressed in
cal/cm^2 and is derived from the determined value of the arc thermal performance value
(ATPV) or energy of breakopen threshold (E BT) (should a material system exhibit a
breakopen resoponce below the APTV value). Arc rating is reported as either APTV or
E bt, whichever is the lower value.
Barricade - CORRECT ANSWER-A physical obstruction such as tapes, cones, or Aframe-type wood or metal structures intended to provide a warning and to limit access.
Barrier - CORRECT ANSWER-A physical obstruction that is intended to prevent contact
with equipment or energized electrical conductors and circuit parts or to prevent
unauthorized access to a work area.
Shock boundaries - CORRECT ANSWER-Limited approach boundary,
Restricted approach boundary,
Prohibited approach boundary (not in 2015)
Limited approach boundary - CORRECT ANSWER-An approach limit at a distance from
an exposed energized electrical conductor or circtuit part within which a shock hazard
exists.
Restricted approach boundary - CORRECT ANSWER-An approach limit at a distance
from an exposed energized electrical conductor or circuit part within which there is an
increased likelihood of electric shock, due to electrical arc-over combined with
inadvertent movement, for personnel working in close proximity to the energized
electrical conductor or circuit part.
Arc Flash Boundary - CORRECT ANSWER-When an arc flash hazard exists, an
approach limit at a distance from a prospective arc source within which a person could
receive a second degree burn if an electrical arc flash were to occur.
Electrically safe work condition - CORRECT ANSWER-A state in which an electrical
conductor or circuit part has been disconnected from energized parts, locked/tagged in
accordance with established standards, tested to ensure the absence of voltage, and
grounded if determined necessary.
Hazard - CORRECT ANSWER-A source of possible injury or damage to health
Incident Energy - CORRECT ANSWER-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 calories per square centimeter.
Incident energy analysis - CORRECT ANSWER-A component of an arc flash risk
assessment used to predict the incident energy of an arc flash for a specified set of
conditions.
Qualified person - CORRECT ANSWER-A person who has demonstrated skills and
knowledge related to the construction and operation of electrical equipment and
installations and received safety training to identify and avoid the hazards involved.
Risk - CORRECT ANSWER-A combination of the likelihood of occurrence of injury or
damage to health and the severity of injury or damage to health that results form a
hazard.
Risk assessment - CORRECT ANSWER-An overall process that identifies hazards,
estimates the potential severity of injury or damage to health, estimates the likelihood of
occurrence of injury or damage to health, and determines if protective measures are
required.
Working on (energized electrical conductors or circuit parts). - CORRECT ANSWERIntentionally coming in contact with energized electrical conductors or circuit parts with
hands, feet, or other body parts, with tools, probes, or with test equipment, regardless of
the PPE a person is wearing. There are two categories of "working on": Diagnostic
(testing) is taking readings or measurements of electrical equipment with approved test
equipment that does not require making any physical change to the equipment; repair is
any physical alteration of electrical equipment (such as making or tightening
connections, removing or replacing components, etc.).
Exposed (as applied to energized electrical conductors or circuit parts) - CORRECT
ANSWER-Capable of being inadvertently touched or approached nearer than a safe
distance by a person. It is applied to electrical conductors or circuit parts that are not
suitably guarded , isolated, or insulated.
Guarded - CORRECT ANSWER-Covered, shielded, fenced, enclosed, or otherwise
protected by means of suitable covers, casings, barriers, rails, screens, mats, or
platforms to remove the likelihood of approach or contact by persons or objects to a
point of danger.
Isolated (as applied to location) - CORRECT ANSWER-not readily accessible to person
unless special means for access are used
Insulated - CORRECT ANSWER-Separated from other conducting surfaces by a
dielectric (including air space) offering a high resistance to thee passage of current
Ground fault - CORRECT ANSWER-An unintentional, electrically conducting connection
between an underground conductor of an electrical circuit and the normally non-currentcarrying conductors, metallic enclosures, metallic raceways, metallic equipment, or
earth.
