Construction electrocution is one of the Fatal Four hazards, killing 82 construction workers in 2024 and causing severe, life-altering injuries to hundreds more each year. Electrical injuries in construction occur from contact with overhead power lines, contact with energized conductors on the job site, failure to implement lockout/tagout (LOTO) procedures before electrical work, and use of damaged or improperly grounded electrical tools and equipment. OSHA's construction electrical standards, 29 CFR 1926 Subpart K (1926.400 through 1926.449), establish detailed requirements for electrical safety in construction including minimum approach distances to power lines, LOTO procedures, grounding of equipment, and use of ground-fault circuit interrupters (GFCIs). Third-party defendants in construction electrocution cases include the electrical subcontractor, the general contractor who failed to coordinate de-energization, the property owner (for pre-existing electrical hazards on the property), and potentially the utility company for failure to de-energize overhead lines during construction.

Overhead Power Line Proximity — A Leading Cause of Construction Electrocution

OSHA 29 CFR 1926.1408 requires minimum clearance distances of 10 feet from energized overhead power lines up to 50kV for cranes and equipment, with greater distances for higher voltages. Contractors must either arrange for the utility to de-energize and relocate lines, install insulating line guards, or maintain the specified minimum approach distances and post warning lines visible from the work area. Failure to follow these requirements when cranes, boom trucks, or elevated platforms operate near overhead lines is a leading cause of construction electrocution and a clear basis for OSHA citation and civil negligence liability.
