Barricade tape, sometimes called caution tape or warning tape, is a brightly colored ribbon typically made from polyethylene or polypropylene. It's printed with cautionary messages such as “Caution,” “Do Not Enter,” or “Danger.” Unlike more permanent barriers like fences or cones, this tape offers a temporary solution that can be quickly set up and just as easily removed. It's the first line of visual communication to warn individuals about potential hazards.
