Is it true that a qualified person is never permitted to cross the restricted approach boundary?

A qualified person is defined in NFPA 70E as someone who has skills and knowledge related to the construction and operation of the electrical equipment and installations, along with safety-related work practices. This training empowers them to assess the risks associated with working near energized electrical parts, including those that are within approach boundaries.

Crossing the restricted approach boundary is not outright prohibited for qualified persons. Instead, they can cross this boundary under specific conditions, provided they have received the proper training and possess a clear understanding of the associated risks. This context is significant because the conditions and safety measures allow qualified personnel to perform necessary tasks while minimizing hazards.

Qualified persons may need to enter such areas to perform specific work tasks or inspections, but they must follow strict safety protocols and guidelines established by the employer and overarching safety regulations, including PPE requirements and risk assessments.

Thus, the correct answer indicates that qualified personnel can indeed enter this boundary if they are appropriately trained, aware of best practices, and equipped with suitable safety measures to mitigate risks while working near live equipment.
