In the context of NFPA 70 Live Work, who can enter the restricted approach boundary?

In the context of the NFPA 70 regulations regarding Live Work, only qualified persons are permitted to enter the restricted approach boundary. A qualified person is defined as an individual who has the training, skills, and knowledge necessary to perform work on or near exposed energized parts. This requirement is established to ensure safety, as working close to live electrical equipment poses significant hazards, including electrical shock, burns, or other serious injuries.

Qualified persons have received specific training that equips them with the understanding of the risks involved and the appropriate safety measures to mitigate those risks. They are familiar with the relevant safety standards, as well as the procedures for safely working near electricity, which plays a crucial role in protecting both themselves and others in the vicinity.

Other options mentioned in the question lack the necessary focus on safety defined by the NFPA guidelines, as they may not ensure that individuals with inadequate training or understanding of hazards are kept out of potentially dangerous situations. Therefore, access to the restricted approach boundary is strictly limited to ensure the utmost safety in environments with energized electrical equipment.
