Pipeline markers come in many shapes and sizes, but their effectiveness is based on a similar set of characteristics, including:
- Visibility: Can the warning message, not just the marker, be seen from any direction, not just the front and back?
- Message design: Is the message clear and easy to read from a distance?
- Safety: Is the marker you install in the right-of-way safe? What happens if a mower, all-terrain vehicle (ATV) or cyclist accidentally runs into the marker?
What is the purpose of a permanent marker from a damage prevention perspective?
It has to be reminding potential excavators to locate the pipeline before digging.
An effective warning message design is one that uses sharply contrasting colours and provides maximum visibility. It should feature the Dial Before You Dig symbol, alerting excavators to locate all buried facilities before digging.
