APWA Color Standards for Utility Marking Flags
Utility marking flags are critical for construction, excavation, and underground utility locating.
Our factory produces utility marking flags that follow the APWA (American Public Works Association) uniform color codes for safety and compliance.
Each color represents a different type of underground facility:
Red: Electric power lines, cables, conduit
Yellow: Gas, oil, steam lines
Orange: Telecommunication, alarm, signal lines
Blue: Potable water
Green: Sewers and drain lines
Pink: Temporary survey markings
White: Proposed excavation limits
Purple: Reclaimed water, irrigation, slurry
Using standardized flags for marking utilities helps prevent accidents, injuries, and utility damage on job sites.
All our marking out flags are made of durable, UV-resistant plastic material for long-term outdoor use.
