Overhead Power Line Signs

Overhead power line signs should alert workers to the presence of energized lines above and warn against operating cranes, lifts, or equipment within minimum clearance distances, and our danger overhead power lines sign and caution high voltage overhead line sign offer multiple message options from general awareness to Danger-level warnings for high-voltage transmission lines.

OSHA requires that workers be warned about overhead electrical hazards on construction sites, particularly when equipment operation near power lines creates a risk of contact, and our overhead power line signs are available in Caution, Warning, and Danger signal words appropriate to the voltage level present to help fulfill this requirement.

Aluminum is the best material for outdoor overhead power line signs because it resists rust, fading, abrasion, and chemical exposure, and our overhead power lines with up arrow sign and other aluminum options are built for permanent outdoor installation and can be mounted on fences, poles, or equipment with pre-drilled holes.

Yes, our high voltage overhead lower crane boom OSHA danger sign is one example of our equipment-specific options, and our customizable overhead power line sign templates let you specify voltage, required clearance distance, or site-specific safety instructions in durable materials with reflective versions available for improved visibility on outdoor job sites.
