Power lines are the number one cause of crane related deaths.

• A. True
• B. False
• C. Not sure
• D. Unknown

Answer: (A)

Overhead electrical hazards are the biggest danger in crane operations because electricity can arc and energize the crane even without direct contact. The metal parts of the crane—boom, gantry, and rigging—conduct electricity, so getting too close to power lines or touching them can deliver a fatal shock to the operator and nearby workers. Because of this, the safest practice is to treat lines as energized at all times: establish safe clearance before any lift, de-energize lines if possible, or move the crane away and coordinate the lift with a qualified spotter or supervisor. Safety data and industry experience show that electrical contact or close approach to power lines is the leading cause of crane-related fatalities, more so than other common crane incidents. That’s why this statement is considered true.
