Arc Flash Hazard - ANSWER A source of possible injury or damage to
health associated with the 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 cal/cm ^2 and is derived from the determined value of the arc
thermal performance value (ATPV) or energy of breakopen threshold (Egr) (should a material
system exhibit a breakopen response below the ATPV value). Arc rating is reported as either
ATPV or EBt, whichever is the lower value.
Informational Note No. 1: Arc-rated clothing or equipment indicates that it has been tested
for exposure to an electric arc.
Informational Note No. 2: ATPV is defined in ASTM F1959/ F1959M, Standard Test Method
for Determining the Arc Rating of Materials for Clothing
balaclava - ANSWER .
An arc-rated head-protective fabric that protects the neck and head except for a small
portion of the facial area.
Boundary, Arc Flash - ANSWER When an arc flash hazard exists, an approach limit from
an arc source at which incident energy equals 1.2 cal/ cm^2
Boundary, Limited Approach - ANSWER An approach limit at a distance from an exposed
energized electrical conductor or circuit part within which a shock hazard exists.
1
, Boundary, Restricted Approach - 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.
Electrical Safety Program - ANSWER A documented program that identifies policies,
procedures, principles and safe work practices to protect workers exposed to electrical
energy.
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.
Maintenance, Condition of - ANSWER The state of the electrical equipment considering
the manufacturers' instructions, manufacturers' recommendations, and applicable industry
codes, standards, and recommended practices.
Qualified person - ANSWER One who has demonstrated skills and knowledge related to
the construction and operation of electrical equipment and installations and has received
safety training to identify the hazards and reduce the associated risk.
Risk - 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 from a hazard.
risk assessment - ANSWER An overall process that identifies hazards,
estimates the likelihood of occurrence of injury or damage to health, estimates severity of
injury or damage to health, determines if protective measures are required
working distance - ANSWER Distance.
The distance between a person's face and
chest area and a prospective arc source.
