3.1 PLANNING: Plan your fall protection system prior to installation of the Concrete Wedge Anchor. Account for all factors
that may affect your safety before, during and after a fall. Consider all requirements, limitations and specifications defined
in Section 2 and Table 1.
MOUNTING HOLE LOCATION: The allowable distance from an edge or corner for mounting the Concrete Wedge Anchor will
vary with the thickness and width of the concrete. Mounting hole location requirements are listed in Table 1. Do not install
the hole in an exposed location that could have ice form around the anchor. Whenever installing the anchor in an existing
hole, verify the hole diameter and depth are correct along with specifications from Table 1. If unsure, drill a new hole in a
new location meeting the specification from Table 1.
3.2 INSTALLING THE CoNCrETE WEdGE ANCHor: The concrete in which the anchor is secured must have a
compressive strength of 20.7 MPa (3,000 psi). The Concrete Wedge Anchor is not intended for use in lightweight concrete,
hollow block, grout, stone, wood, steel, or any other substrate. The concrete base material must be at least 12.7 cm
thick. Use Figure 2 call outs for install references. To install the Concrete Wedge Anchor:
1. Select the Concrete Structure and hole location meeting requirements from Table 1. Concrete must be free of cracks.
;
Before drilling holes, inspect the hole location to prevent drilling into power transmission cables or other live
utilities.
2. Drill a 7.62 cm (3 in.) or deeper hole at the desired mounting location with a rotary hammer and industrial grade 20
mm (.75 in.) rotary hammer drill bit.
3. The mounting hole must be free of debris for the Concrete Wedge Anchor to develop maximum strength. Blow all
debris out of the hole with a blow-out bulb or compressed air. If reusing an existing hole, inspect thoroughly for
debris and a uniform surface.
4. Place your thumb in the anchor Swivel Ring (A) and pull up on the Trigger (C) with two fingers until fully retracted.
5. Insert the anchor into the mounting hole until the Release Plug (D) seats against the concrete surface and then
release the Trigger (C).
6. Pull strongly up on the anchor Swivel Ring (A) to set the anchor. The gap between the underneath of the lip of the
Release Plug to the concrete surface must be equal to or less than 6.35 mm (.25 in)(Figure 8)
3.3 rEMoVAL oF THE CoNCrETE WEdGE ANCHor: To release the Concrete Wedge Anchor, push down on the Release
Plug (D) and pull up on the Trigger (C). If the anchor does not release, tap the Release Plug (D) down into the hole and
repeat the process (see Figure 10). The Concrete Wedge Anchor may be reused if it has not been subjected to a fall force
and it must pass inspection items from Section 5 and Table 2.
;
Do not attempt to pry up on the release plug with any tools or forcibly remove the anchor as this can cause
damage the Anchor (see Figure 10).
4.0 USE
4.1 BEForE EACH USE: Verify that your work area and Personal Fall Arrest System (PFAS) meet all criteria defined in
Section 2 and a formal Rescue Plan is in place. Inspect the Concrete Wedge Anchor per the 'User' inspection points
defined on the "Inspection and Maintenance Log" (Table 2). If inspection reveals an unsafe or defective condition, do not
use the system. Remove the system from service and destroy, or contact 3M regarding replacement or repair.
4.2 FALL ArrEST CoNNECTIoNS: The Concrete Wedge Anchor is used with a Full Body Harness and Energy Absorbing
Lanyard or Self-Retracting Device (SRD). Connect the Lanyard or SRD between the D-Ring on the Concrete Wedge Anchor
and the back Dorsal D-Ring on the Harness as instructed in the instructions included with the Lanyard or SRD.
;
Safe Work Area: Never work in a location that could load the anchor in the event of a fall at an angle greater
than 90° from the centerline of the hole (Figure 9).
;
Horizontal Lifeline Connections: The Concrete Wedge Anchor cannot be used as an end anchor point for a
Horizontal Lifeline (HLL).
1 Qualified Person:
An individual with a recognized degree or professional certificate, and extensive experience in Fall Protection. This individual must be capable
of design, analysis, evaluation, and specification in Fall Protection.
2 Competent Person:
One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazard-
ous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
