The National Marker Company signage with the legend “SAFETY FIRST - WEAR YOUR SAFETY GLASSES” clearly marks the areas where wearing safety glasses is mandatory. It is often seen in industrial facilities and construction sites to ensure personnel safety. The safety glasses sign uses contrasting colors and clear, bold font to ensure clear visibility in most lighting conditions and even from a distance. The material is UV resistant, chemical resistant, graffiti proof and has an NMC Sign Muscle coating that protects the text against fading, scratches, scuffing, mold, and moisture.
