This 10" x 14" rigid plastic safety sign alerts workers and equipment operators to overhead high-voltage power lines in utility work zones, substations, and construction sites near electrical infrastructure. The bold WARNING header and clear messaging help prevent contact accidents with energized conductors.
Constructed from durable rigid plastic, this sign withstands outdoor exposure including UV rays, rain, and temperature extremes. Pre-drilled mounting holes in all four corners enable quick installation on utility poles, fence lines, equipment barriers, or temporary jobsite posts. The weather-resistant material maintains legibility through years of field service.
Key Features
High-Visibility Warning — Bold black and orange WARNING header with clear "HIGH VOLTAGE WATCH FOR OVERHEAD LINES" text ensures message visibility from a distance.
Rigid Plastic Construction — Weather-proof material resists fading, cracking, and warping in outdoor conditions.
Pre-Drilled Mounting Holes — Corner holes in all four corners allow secure attachment to poles, posts, or fencing with standard hardware.
Professional Size — 10" x 14" dimensions provide adequate visibility without obstructing work areas.
Lightweight Durability — At 0.19 lb, the sign installs easily while maintaining structural integrity in wind and weather.
Applications
Used by utility crews, electrical contractors, and construction site managers to mark overhead power line hazard zones. Ideal for substations, transmission line work areas, equipment yards, and construction sites where cranes or tall machinery operate near energized conductors. Helps satisfy OSHA 1926.416 requirements for marking overhead power line hazards.
