Under NFPA 70 Live Work, who is allowed to enter the restricted approach boundary?

1. Anyone with basic electrical knowledge

2. Only qualified persons

3. Anyone under supervision

4. Electricians with at least one-year experience

The correct answer is: Only qualified persons

The correct choice indicates that only qualified persons are permitted to enter the restricted approach boundary as defined by NFPA 70, which relates specifically to electrical safety. A qualified person is someone who has received training and has the necessary knowledge and experience to work safely with or near energized electrical installations. This designation ensures that individuals understand the risks involved and the proper safety protocols required to minimize danger when working near live electrical parts. The restricted approach boundary is a safety zone intended to protect individuals from potential electrical hazards, such as electric shock or arc flash. Access to this area is strictly limited to those who can effectively assess the risks and implement the necessary safety measures to protect themselves and others. Other choices do not align with the specific requirements outlined in NFPA 70. Basic electrical knowledge, for instance, may not suffice without the training and experience necessary to operate safely in potentially hazardous environments. Supervised individuals might not have the requisite skills and knowledge to conduct independent assessments required in such situations, while electricians with only one year of experience could still lack sufficient training, especially if they are not deemed qualified under the standards of NFPA 70. Thus, the emphasis is rightly placed on ensuring that only those with a well-defined level of expertise and training can enter this critical
