F4P carries barricade tape, underground tape, and flags as part of its Safety Marking product line. All serve different purposes during construction. Let’s look into the importance of underground tape and flags.
Underground tape is used to locate and prevent damage to buried utility lines. With it, workers are informed to stop digging due to its easy-to-identify, bold font and color.
F4P has two types of underground tape: detectable and non-detectable. Detectable underground tape is found easily with a non-ferrous metal locator. Non-detectable underground tape, however, follows the American Public Works Association (APWA) standard of color coding to communicate the type of line:
White: proposed excavation
Pink: temporary survey markings
Red: electric power lines, cables, conduit, and lighting cables
Yellow: gas, oil, steam, petroleum, or gaseous materials
Orange: communication, alarm or signal lines, cables, or conduit
Blue: potable water
Purple: reclaimed water, irrigation, and slurry lines
Green: sewer and drain lines
If underground tape serves as an underground warning for utility lines, then flags serve as an above ground warning. Flags are used to communicate what’s being marked such as buried gas or water lines. Flags are color coded and also follow the APWA standard to identify the type of line.
The addition of flags helps the construction process run quickly and efficiently. Workers can see the flags and know what type of line is being identified, making it easier for them to proceed.
Due to their visibility, flags are more prone to removal than tape. Removal of flags can jeopardize the safety of a job site, putting workers and the public in danger.
Using underground tape and flags are not only a safe choice, but a smart financial one as well. They help avoid additional costs, such as repairs or service interruptions, that could occur when utility lines are damaged.
