What the AI looks for in Safety Flags
- Utility colour code
- Follow the APWA uniform colour code: red for electric, yellow for gas, oil or steam, orange for communications, blue for potable water, green for sewer, purple for reclaimed water, pink for temporary survey, and white for proposed excavation. Excavators read flag colour as the type of buried utility, so the wrong colour is a real hazard.
- Projecting load flags
- Under 49 CFR 393.87, loads that project beyond the vehicle need red or orange flags at least 12 inches square. State oversize rules may require larger flags. Undersized or faded flags fail inspection and are not seen.
- Durability
- Use fade-resistant vinyl or nylon on stiff wire staffs long enough for your ground cover. Faded or flattened flags are lost in grass and snow.
Brands that matter
- Presco: Marking flags and survey supplies.
What to avoid
- Marking flags in colours that conflict with the utility colour code
- Lightweight fabric flags for highway load marking
