What does a red mark out line mean?

• A. Gas/Steam
• B. Water
• C. Proposed Excavation
• D. Electric

Answer: (D)

Red mark-outs indicate electric power lines, cables, or conduits buried underground. This color coding helps crews distinguish different buried utilities so they don’t strike energized equipment during digging. So the red line is signaling electric when you’re planning or performing excavation. Other colors mark other utilities (for example, yellow for gas/oil/steam, blue for water, pink for proposed excavation), which is why they don’t fit the red indication. If you see red marks, avoid digging in that area and coordinate with the utility or call 811 to get the lines located and de-energized if needed.
