Pipeline markers are required by the Department of Transportation (DOT) and API standards to prevent accidental rupture during digging. A hit pipeline can cause explosions, environmental damage, and loss of service, which is why they are often used with utility marking tape.
Pipeline signs (or pipeline markers) are posts or signs used to identify the location of underground pipelines. They warn excavators of buried gas, oil, or water lines and provide emergency contact information. These are essential for promoting general safety signs in construction zones.
A compliant marker must display the warning signal word (warning/danger), the product being transported (e.g., "natural gas"), the operator's name, and a 24-hour emergency phone number. This is similar to the detailed information required on radiation warning labels.
Pipeline markers follow the APWA color code: Yellow for gas/oil/steam, Blue for water, Green for sewer, Red for electric, and Orange for communication lines. This helps crews instantly identify the utility type.
Markers should be placed directly over the centerline of the pipe, at road and railroad crossings (see railroad safety signs), and at intervals
Keep workers, contractors, and emergency responders accurately informed about pipeline contents, flow direction, and hazard levels with pipeline signs that provide clear and reliable identification across any facility or job site. Misidentified pipelines can lead to serious accidents, chemical exposure, and costly operational errors, making accurate and durable pipeline signage an essential part of any industrial safety program. Our pipeline signs are designed to meet industry standards while ensuring every pipe in your facility is clearly and consistently labeled.
