Step 4
➤ With temporarily attached ledgers and a single-han-
dle step ladder, the leading side protection can be
installed from a secured position. Alternatively, steel
decking 320mm can be used. The ledgers in the first
scaffold position provide the necessary fall protec-
tion here.
Step 5
➤ After the installation of the guardrail, a temporary
level is formed from two steel layers on the opposite
side of the stair landing. As with the tubular ledgers
and diagonals, the wedges of the ridge rail are
wedged against the rosettes until they bounce. The
ledgers of the top layer can now be extended all
around.
