Masonry Wall Bracing
A “Limited Access Zone” must be established on the
unscaffolded side of a masonry wall. The objective of
this standard is to prevent masonry walls from
collapsing onto persons exposed to them. This can be
done by supporting or bracing the walls or by restricting
exposure within the probable fall path of the walls. The
only employees permitted in the zone are those "actively
engaged in constructing the wall". The size of the zone is
based on the height of the "unsupported" portion of the
wall plus four feet. For example, if the wall being
constructed is up to a height of 80 feet, and all but 10
feet of the height is supported, the Limited Access Zone
required would be 14 feet.
