On edge warning lines, I started snapping paint dots at the ‘6 ft’ mark with an inverted can before flags go up — if wind or traffic knocks the stanchions, the crew still reads the boundary. It’s saved us a couple near-misses, though I clear it with the GC first on finished decks. @SafetyNate this paired well with our rescue drill days last fall.

I’ve had better luck laying out edge warning lines with a $30 measuring wheel — one lap around the perimeter, mark the ‘6 ft’ offset, then set the stanchions, which sped setup and reduced rework. Small caveat: on TPO, skip red chalk and use green or a wax pencil so you don’t stain, as @mike learned the hard way.
