DETECTABLE WARNING TAPES
Overview
Detectable Warning Tape for underground usage or UGDT is buried directly above underground utility lines and warns workers to stop digging before accidentally digging into the underground lines. When used correctly, the underground detectable tape can mitigate the risk of inaccurate or dangerous digging around electrical, gas, water, communication, or oil lines. And when dig-ins are avoided, the associated costly service interruptions and unnecessary repair expenses are also avoided. Plus, preventing the accidental dig-ins also helps keep evacuation crews safe from harm.
As an additional advantage, underground detectable tape uses colour to communicate the type of buried utility line. Underground detectable tapes conform to the uniform colour standard created by the APWA and local bodies for warning tapes.
Colour Codes include:
⦁ White for Proposed excavation
⦁ Red for cables, electric power lines, conduit
⦁ Pink for temporary survey markings
⦁ Orange for communication, signal lines conduit, alarm
⦁ Yellow for steam, petroleum, gas, oil, gaseous substances
⦁ Purple for reclaimed water, slurry lines, irrigation
⦁ Blue for potable water
⦁ Green for drain lines and sewers.
