What precautions should be taken when working in locations containing uninsulated energized overhead lines that are not guarded or isolated?

  • Inform the person or organization that operates the lines to de-energize them and visibly ground them at the point of work
  • Energize the lines to reduce the risk of accidental contact
  • Prevent employees from contacting the lines directly with any unguarded parts of their body or indirectly through conductive materials, tools, or equipment (correct)
  • Use protective measures such as guarding, isolating, or insulation to prevent contact with the lines

    • Who is responsible for determining if the overhead electrical lines are insulated for the lines' operating voltage?

  • A qualified person (correct)
  • The employee performing the work
  • The employer who operates the lines
  • An external safety inspector

    • What should be done if arrangements are made to use protective measures instead of de-energizing the overhead electrical lines?

  • Energize the lines to minimize the risk of accidental contact
  • Prevent each employee from contacting the lines directly or indirectly through conductive materials, tools, or equipment (correct)
  • De-energize and visibly ground the lines at the point of work
  • Use insulating materials on the lines
