The Barricading Warning Tape is a colored plastic film made from low density polyethylene. It is printed with a message to warn the public of buried utilities like electric cables, telecommunications or water pipelines. It is normally installed a particular distance directly above the service line to be marked so that any future workmen will be aware of the cable or pipeline. The Barricading Warning Tape only provide a visual warning to excavators. It is not supposed to provide any protection or resistance to further excavation.
