How far from the surface should red tape be placed to warn anyone digging of energized cables?

Red tape should be placed 1 foot from the surface to alert individuals that there are energized cables beneath. This practice is important for safety during digging or excavation work, as it serves as a visual warning to prevent accidental contact with underground utilities.

The 1-foot placement ensures that there is an adequate buffer, allowing workers to be aware of potential hazards just before they start digging deeper, helping to avoid any accidents. Other placements, such as 2, 3, or 4 feet, may not provide the same level of alertness at a crucial point when someone is preparing to excavate, potentially leading to unsafe situations if the warning is too far away from the digging area.
