NFPA 70E & NFPA 820 well arranged Hierarchy of Risk Control Method -ANS-[A. Elimination] [B. Substitution] [C. Engineering Controls] [D. Awareness] [E. Administrative Controls] [F. PPE] Number of steps to Establish/Verify an Electrically Safe Working Condition according to the NFPA 70E 2018: -ANS-[B. 8 ] How often should visual and audible alarm signaling systems be tested to verify functionality ? -ANS-[A. Quarterly ] What kind type of alarm signaling notification appliances are required for entrances to remote spaces that are not constantly attended ? -ANS-[ C. Visual and audible alarms or dual light warning systems] Limited Approach Boundary definition -ANS-An approach limit at a distance from an exposed energized electrical conductor or circuit part within which a shock hazard exists. Restricted Approach Boundary definition -ANS-An approach limit at a distance from an exposed energized electrical conductor or circuit part within which an increased likelihood of electric shock, due to electrical arc-over combined with inadvertent movement. -ANS-
