The National Marker Company sign with legend ?CAUTION - STAIRWAY? shows the message in clear, bold yellow text on black base with black text on yellow base. The use of contrasting colors ensures that the sign garners attention, while the font makes it readable even from a distance. The OSHA style stairway caution sign is meant to prevent accidents by properly labelling staircase areas at banks, shopping centers, construction sites, and other public places. The rectangular caution signage complies with OSHA standards and has NMC Sign Muscle coating to protect the text against fading, scratches, scuffing, mold, and moisture.
