What is one of the most common causes of injuries and fatalities for riggers and crane operators?

• A. Mechanical failure of the crane
• B. Electrocution from power line contact
• C. Fatigue from long shifts
• D. Falls from a raised load

Answer: (B)

Electrocution from contact with overhead power lines is the most dangerous and frequent fatal risk for riggers and crane operators because electricity can travel through the crane, rigging, or load and shock workers even with indirect contact. A live line or a crane component that touches a line can create an electrical path to ground, and an arc can jump across a small gap, delivering a fatal current to anyone nearby. This hazard is relentless and present on many job sites, making it the leading cause of fatal injuries in this field. Other hazards like mechanical failure, fatigue, or a load dropping are serious but tend to be less likely to cause fatalities on a broad scale, especially when devices are well maintained, shifts are managed, and loads are rigged with proper procedures. The immediate, life-threatening nature of electrical contact with power lines keeps electrocution at the top of the risk list. Preventive actions focus on keeping distance or eliminating the hazard altogether: maintain the prescribed clearance from power lines, de-energize lines when work near them is required, use a dedicated spotter to enforce distance, and employ nonconductive equipment and proper rigging practices. These steps are essential to remove the electrical danger and protect workers.
