Chapter 2 Safety Related Maintenance Requirements
Chapter 3 Safety Requirements for Special Equipment
Annexes (Article 350)
Arc Flash Hazard answer >>> A dangerous condition associated with the possible
release of energy caused by an electric arc
Arc Rating answer >>> The value attributed to materials that describes their
performance to exposure to an electrical arc discharge. The arc rating is expressed
in call/cm^2 and is derived from the determined value of the arc thermal
performance value (ATPV) or energy of break open threshold (E BT) (should a
material system exhibit a break open response below the APTV value). Arc rating
is reported as either APTV or E but, whichever is the lower value.
Barricade answer >>> A physical obstruction such as tapes, cones, or A-frame-
type wood or metal structures intended to provide a warning and to limit access.
Barrier 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.
, NFPA 70
Shock boundaries answer >>> Limited approach boundary,
Restricted approach boundary,
Prohibited approach boundary (not in 2015)
Limited approach boundary 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 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 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 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 answer >>> A source of possible injury or damage to health
