NFPA 70E Terms Well Arranged
NFPA 70E Terms Well Arranged Arrangement of 70E -ANS-Introduction (Article 90) Chapter 1 Safety Related Work Practices Chapter 2 Safety Related Maintenance Requirements Chapter 3 Safety Requirements for Special Equipment Annexes (Article 350) Arc Flash Hazard -ANS-A dangerous condition associated with the possible release of energy caused by an electric arc Arc Rating -ANS-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 -ANS-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 -ANS-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 -ANS-Limited approach boundary, Restricted approach boundary, Prohibited approach boundary (not in 2015) Limited approach boundary -ANS-An approach limit at a distance from an exposed energized electrical conductor or circtuit part within which a shock hazard exists. Restricted approach boundary -ANS-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
