The National Marker Company caution signage instructs workers or employees to wear ear protection beyond a specific point at a facility. It is often used at construction sites or industrial facilities where high decibel noise can damage hearing. The caution signage has the legend ?CAUTION ? Ear protection required beyond this point.? printed in legible font to give more readability to the message. The sign is UV resistant, chemical resistant and graffiti proof. It has black text on yellow base with white text on a black base and a head with earmuffs graphic for easy understandability. The rectangular caution sign complies with ANSI standards and has an NMC Sign Muscle coating to protect the text against fading, scratches, scuffing, mold, and moisture.
