Some people call this Lockout/Tagout, but that’s actually only part of the process. For exposed 480 VAC energized conductors and using NFPA 70E Table 130. 1 Limited Approach Boundary • To help protect workers from shock and arc flash hazards, the NFPA has established the concept of approach boundaries. You will learn important on-the-job safety considerations for electrical maintenance and avoiding electrocution risk. POLICY. The 2015 edition of NFPA 70E defines the arc flash boundary (AFB) as, “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. 4 (D) (a) Alternating Current (AC) Systems. • A shock hazard is defined as “a source of possible injury or damage to health associated with current through the body.
