The National Marker Company entry signage clearly states that there is no admittance for anyone except employees of a particular facility or an office. The legend ?NOTICE - NO ADMITTANCE ? EMPLOYEES ONLY? is printed in Black on a White base and in White on a Blue base. The employees only notice signage has its message printed in legible letters which make it easier to read. The notice signage complies with OSHA 29 CFR-1910.145 standards and is graffiti proof, UV resistant and chemical resistant. Also, the NMC Sign Muscle coating on the sign helps protect the text from moisture, fading, mold, scuffing, and scratches.
