National Marker Company sign with legend “CAUTION – PERSONAL PROTECTIVE EQUIPMENT REQUIRED BEYOND THIS POINT” is used to ensure that safety guidelines are being followed at a workplace. The caution sign is mostly used at construction sites and industrial facilities to inform the visitors and workers that wearing personal protective equipment is mandatory beyond an indicated point. It displays the message in contrasting colors and bold font to ensure better visibility in most lighting conditions and even from a distance. The caution signage has NMC Sign Muscle coating to protect the text against fading, scratches, scuffing, and moisture and complies with OSHA standards.
