Use a minimum of 48 mm thick Number 1 Grade spruce-pine-fir (SPF) planking or better. What are minimum recommendations for the deck? Back to top
Weather, rot, and general use can deteriorate the planks. Platform decks should be slip-resistant and should not accumulate water. Damage can occur if the platforms are dropped or thrown. Discard immediately any planks showing these or other defects.
Splits wider than 10 mm (3/8 in), lengthwise closer than 75 mm (3 in.) to the edge of the plank, or lengthwise longer than ½ the length of the plank are not acceptable. Check scaffold planks for large knots, worm holes, steeply sloping grain at the edges, spike knots, and splits.Lay planks side by side across the full width of the scaffold.Make sure that adjoining planks are of uniform thickness for an even platform.
