the direct supervision of a qualied person.
The qualied person must ensure that the
erection is carried out properly, and that
the correct components and materials are
being used. All equipment must be inspected
before use to ensure that it is in good repair
and suitable for the intended use.

on any soil or unstable ground condition, or
where any levelling adjustment is needed.
The sill must be sound, rigid, and capable
of supporting the maximum loads without
settlement or deformation.

by the action of wind on a secured deck or
by the leverage action of a cantilever side
bracket on the scaffolding. All joints must

standing towers.

sides of a platform where it is possible for
tools and or materials to roll off. The top of
the toeboard must be at least 4 in. above the
platform. If loose materials are to be stacked
above the height of the toeboard, then the
toeboard must be increased in height or
mesh panels must be installed to prevent
materials from falling off the scaffolding.
