Marking flags help keep worksites safe during landscaping, utility, excavation, and construction projects. Use marking flags for above ground marking in a variety of industries. These vibrant marking flags are highly visible and allow for the quick location of buried utility lines, pipes, and sprinklers. Blue colored flags are used for water and irrigation. Blue color is specific to potable drinking water.
The American Public Works Association, a non-profit professional association, created a uniform color code for utility companies, both public and private. The colors have become the marking standard across all industries.
