Once the shear wall is poured and the forms are being removed, place the looped end of the Safe-T-Strap over an embedded re-bar dowel protruding through the top of the shear wall. Safe-T-Strap should be installed six (6) feet back from the perimeter of the building. Once Safe-T-Strap is installed, the forming of the floor continues and Safe-T-Strap is firmly anchored by pouring concrete over the protective sleeve.
Once the fly forms or
conventional forming is removed, Safe-T-Strap will be hanging from the
corner of the sheer wall and the ceiling - six feet back from the
perimeter.
Horizontal life lines
or static lines may be attached to two opposite embedded Safe-T-Strap. Two
workers may then attach their life lines to the horizontal life line, providing
maximum mobility and fall protection. Some jurisdictions may require an
engineer to certify a static line is acceptable for various work practices.
When the fall
hazard has been eliminated from the perimeter, i.e., the exterior wall has
been erected, the Safe-T-Strap is removed by cutting it off at the base.
Where shear walls or
columns do not exist, Safe-T-Strap can be installed by inserting an 8" piece
of rebar through the straps looped end, then inserting that end 4” into the
poured concrete.
Residential Installation Procedures
Safe-T-Strap consists of a two inch wide webbing, with a
2-1/2 inch d-ring attached at one end. The other end of the Strap is folded and
stitched in place. (All nails used to secure the Safe-T-Strap must be hammered
through the folded stitched area.) (1)The Safe-T-Strap must be attached using
standard 3" framing nails and provides an anchor point with a tested failure
strength provided the following steps are adhered to.
(1)Using two ardox
nails, the folded stitched end of the Safe-T-Strap is attached to the top plate
of the wall or truss. (Note: These nails must be hammered in place securely.) (2 & 3)
The Safe-T-Strap is then wrapped once around the single two-by-four (or double
two-by-six) (4)and a third nail is hammered through both strap surfaces.
The same procedure
applies to the attachment of the Safe-T-Strap to the roof truss. (1)First two
ardox nails are inserted in the folded stitched end (Note: In the case of a
two-by-four roof truss, the driven nails must be hammered over the opposite side
of the strap before proceeding with step two) (4)then the remaining length of the
strap is wrapped around the truss twice and a third nail is driven through both
sections and folded over again. Note: It is the recommendation of the
Safe-T-Strap Company that before the truss is raised, fastened and braced in
place, a lifeline of sufficient length is attached to the Safe-T-Strap to
ensure access to the roof.
When installing
Safe-T-Strap on floors, nails must be inserted through the stitched looped end
opposite the d-ring. Straps should be placed a measured distance from the
perimeter of the floor, including the length of the lanyard used to ensure
adequate travel restraint. It is a requirement of the engineered system that
four (4) double-headed (duplex) nails secure the strap to the floor. They must
be secured into a floor joist below the plywood floor.
The placement of the
straps on both the top plate of the second storey wall, the roof trusses and the
floor will depend on the style of the house. The recommended placement is
approximately every 6 feet on completion of installation. Safe-T-Strap should
hang at least 12" inches below the bottom of the installed fascia and 12" inches
from the peak of the roof.
