INSTALLATION

3.1 OVERVIEW: Anchorage connectors must be secured to an anchorage structure before they can be used. After this is
done, users may secure to the product through its anchorage connection points.
3.2 PLANNING: Plan your Fall Protection system before starting your work. Account for all factors that may affect your safety
before, during, and after a fall. Consider all requirements and limitations specified in these instructions.
A. SHARP EDGES: Avoid working where system components may be in contact with, or scrape against, unprotected
sharp edges and abrasive surfaces. All sharp edges and abrasive surfaces should be covered with protective material.
B. SYSTEM DEFLECTION: Some anchorage connectors will deflect during fall arrest, which may increase the user's fall
distance. Maximum deflection for the product is given in Table 1. When greater than zero, maximum deflection must
be added to the user's required fall clearance to ensure the user does not strike an obstruction in the event of a fall.
;
For additional fall clearance requirements, see the manufacturer instructions for your connecting subsystem.
3.3 BEFORE INSTALLING: The anchorage connector may be installed on structures meeting the requirements specified in
these instructions. In addition to the requirements listed in Table 1, the installation must meet the following requirements:
A. SURFACE CONTAMINATION: Remove all surface contaminants from the anchorage connector and install location.
Surface contaminants could accelerate wear on the product.
B. BEAM SPECIFICATIONS: The Concrete Anchor Strap may only b e connected to anchoring rebar within beams
of concrete. See Figure 5.1 for beam width and thickness requirements for the product models specified in these
instructions.
C. ANCHOR ORIENTATION: The Concrete Anchor Strap should always be installed with the strap faces parallel with
the concrete surface. See Figure 5.2 for reference. The user's Fall Protection system should be installed to prevent
unintentional loading in unapproved directions. See Table 1 for more information on anchorage requirements.
3.4 INSTALLING THE CONCRETE ANCHOR STRAP:
1. Select a location for the anchorage that will provide the best safety to the user.
2. Once a section of concrete column, or a shear wall has been poured and allowed to cure, place the Web Loop end of the
Self-Retracting Device over an exposed section of Steel Rebar. The anchoring rebar must be at least 4 in. (10 cm) from
the outside face of the poured concrete.
3. Once the Anchor Strap is in place, forming of the floor or column may continue. The concrete anchor will be secured by
making the next pour, and allowing the concrete to cure. Once forms are removed and the concrete has cured, anchors
will remain on the face of a column, or on the seam between shear wall and bottom side of the floor.
4. If the rebar cage has already been completed the Concrete Anchor Strap may be choked around the internal rebar by
folding the Anchor Strap around the rebar and then pulling the D-Ring end through the Web Loop (see Figure 6). All
other stipulations of this manual must still be followed, specifically regarding anchorage strength, position, and concrete
curing before use.
;
Do not use lanyard until it is embedded in cured concrete. The concrete is an essential part of the anchorage strength. Using the
Anchor Strap without concrete support may cause the anchorage connector to fail and could result in serious injury or death.
3.5 REMOVING THE CONCRETE ANCHOR STRAP:
1. Once the fall hazard has been eliminated, the Concrete Anchor Strap must be removed. Use a knife or scissors to cut
the Anchor Strap between the labels and the concrete.
;
The lanyard is not reusable. It must be removed and disposed of once the fall hazard has been eliminated. Attempts to reuse
his product after removal may cause the anchorage connector to fail and could result in serious injury or death.
