OSHA 29 CFR 1926.550: What must be ensured regarding power lines during crane operation?

• A. Make sure power lines are de-energized and separated from the crane, using independent insulated barriers, and maintain clearance
• B. Power lines may remain energized if a barrier is placed
• C. Keep a distance of 1 foot from power lines
• D. Ignore power lines

Answer: (A)

When a crane is operating near overhead power lines, the priority is eliminating the electrical hazard to prevent electrocution or arcing. The required approach is to de-energize the lines and ensure they are separated from the crane, with independent insulated barriers in place, and to maintain a safe clearance between the crane, load, and the lines. This aligns with OSHA’s rule for safeguarding against lines during crane operations: treat the lines as a critical hazard, remove the energy if possible, and physically separate and shield the equipment and workers to maintain a safe distance.

Energizing lines while relying on a barrier does not remove the electrical risk, and a very small clearance (like one foot) is not sufficient to meet the mandated safety distances. Ignoring the lines is not compliant and creates a life-threatening situation.
