The National Marker Company sign with the legend ?SAFETY FIRST - SAFETY IS EVERYBODY'S JOB? is often used in industrial facilities and construction sites. It reminds the workers that workplace safety is a group effort and that it should be a priority. The general safety sign uses contrasting colors to ensure clear visibility from a distance and in most lighting conditions. The material used in the workplace safety sign is UV resistant, chemical resistant, graffiti proof and has an NMC Sign Muscle coating that protects the graphic against fading, scratches, scuffing, mold, and moisture.
