SAFETY CRITICAL AREA

The last sign you’ll ever need.

Printed signs fade and fail—CNC-carved HDPE is permanent.

Precision CNC-carved from a .25” thick, sheet of solid Color Core HDPE, this is not a printed or laminated sign—it’s built to withstand indoor or outdoor industrial environments without peeling, fading, rusting, or rotting.

This SAFETY CRITICAL AREA sign identifies zones requiring strict procedural compliance due to elevated operational risk.

This sign has a YELLOW background with BLACK inner core color, compliant with ANSI Z535 standards for the “CAUTION” category.
