The National Marker Company sign alerts workers, employees or individuals about overhead power lines. It is mostly used at any location with overhead power lines to keep people safe from any accident. The danger signage has the legend “DANGER - OVERHEAD POWER LINES” printed in bold and legible font to give it more readability. The sign is UV resistant, chemical resistant and graffiti proof. It has White text on Red base and Black text on White base. The rectangular danger sign complies with OSHA 29 CFR 1910.145 standards and has an NMC Sign Muscle coating to protect the text against fading, scratches, scuffing, and moisture. The UV- cured, clear coating creates a strong bond and also boosts the color and clarity.
