Frequently Asked Questions
What do the different color construction flags mean?
Different colors of construction flags carry specific meanings — essentially, they tell you what’s buried under the flag. Here are just a few examples of common colors and what they indicate:
- Red – Electrical lines, cables, conduit, and other hazardous materials
- Yellow – Gas, oil, or other flammable materials
- Orange – Communications-related materials like cable and phone lines
- Blue – Water-related items like plumbing lines
- Green – Sewer and other hazardous waste lines
Do underground utility contractors have to use detectable underground utility markers like foil tape?
Requirements for underground utility projects vary by jurisdiction — some building and permitting authorities might require utility builders to use materials that can be picked up by a metal detector to promote the safety of workers and utility locators.
But, even if your jurisdiction doesn’t require you to use items like detectable tape, consider incorporating these as a part of your standard operating procedure. Making sure that your buried utility materials are as visible as possible protects both your equipment and anyone working on/around it.
