Spillways. Provide ladder rungs or handrails, depending on steepness,
up flooding and discharge spillways, to aid in access for inspection of sluice gates and
Dock Floor Irregularities. Graving dock floors should present an
unbroken surface. Cover drainage conduits with gratings that do not protrude above the
floor level. Run service pipes near the sidewalls and bridge them at stairways. Floor
finish should be on a true plane and sufficiently rough to prevent slipping, but not so
rough as to injure blocks.
Painting. Paint obstructions with a striped pattern composed on
contrasting colors as outlined in UFGS 09900N. Paints and Coatings.
Service pipes are customarily painted according to established color
codes, but those below headroom or otherwise forming obstructions
should be painted with contrasting colors in stripes.
Channel pedestrian traffic through safety zones by marking the borders of
pedestrian passageways with traffic zone paint.
