3.1 PLANNING: Plan your fall protection system prior to installation of the Concrete Bolt 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.
3.2 INSTALLING THE CoNCrETE BoLT ANCHor: The Concrete Bolt Anchor can be installed in concrete meeting the
anchorage requirements specified in Table 1. See Figure 7 for proper loading of the Concrete Bolt Anchor. Figure 8
illustrates installation of the Concrete Bolt Anchor. To install the Concrete Bolt Anchor:
1. Mark the location for the placement of the Concrete Bolt Anchor. Observe minimum edge distance and spacing
requirements as specified in Figure 9.
2. Use a rotary hammer and 18 mm, 11/16 in, or 3/4 in bit to drill a hole to a depth of 10.5 cm (4 1/8 in). Clean the
hole using a blow-out bulb or compressed air. The hole must be free of debris for the Concrete Bolt Anchor to develop
full strength.
3. Use a hammer to drive the Concrete Bolt Anchor into the hole. The Concrete Bolt Anchor must be seated firmly
against the D-Ring Bracket. Do not expand the anchor bolt by hand before installation.
4. Tighten the bolt using a 24 mm wrench. Do not use an impact driver for installation. The red cap will shear off at
the appropriate torque and the green seal on the bolt head indicates that the anchor has tightened properly. A
torque wrench is not required for installation. When the red cap has sheared off the anchor, no further adjustment is
necessary.
3.3 rEMoVAL: The Concrete Bolt Anchor can be removed by loosening the bolt with a 19 mm wrench. Parts of the Concrete
Bolt Anchor will remain in the hole permanently. After removal, the hole should be filled with grout or sealant to prevent
reuse of the hole. The bolt cannot be reused and must be destroyed after removal.
3.3 rEUSE: The flanged spacer and D-ring components may be reused if they have not been subjected to a fall force. Refer
to the previous section for removal instructions. Assemble the Concrete Bolt Anchor using 3M supplied parts as shown
in Figure 2. The components should be assembled on the bolt in the following order: flat washer, D-ring bracket, flanged
spacer, black plastic spacer, expansion sleeve, and cone nut. The D-ring bracket must fit over the flanged spacer and
rotate freely. Two tabs on the plastic spacer must engage the matching slots on the expansion sleeve. Do not expand the
anchor bolt by hand prior to installation. Refer back to Section 3.2 for installation procedures.
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 that a formal Rescue Plan is in place. Inspect the Concrete Bolt 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 Concrete Bolt Anchor. Remove the Concrete Bolt Anchor from service and destroy it.
4.2 FALL ArrEST CoNNECTIoNS: The Concrete Bolt 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 Bolt Anchor
and the back Dorsal D-Ring on the Harness as instructed in the instruction manual included with the Lanyard or SRD.
Refer to Figure 10a and 10b for Fall Arrest Connections.
4.3 HorIZoNTAL SYSTEMS: Select Anchorage Connectors can be used as end anchor points for horizontal systems.
Anchorages for horizontal systems must be designed and certified by a Qualified Person
designing and using horizontal lifeline systems. Non-certified anchorages shall not be used for horizontal lifelines. Only
use an anchorage connector that meets the load, moment, and directional requirements for that specified horizontal
system. Non-Fixed, Sliding, or Counterweight Anchorage Connectors should not be used with a horizontal system. Refer
to the instruction manual and installation manual supplied with your horizontal lifeline system for more information on
anchorage and anchorage connector requirements.
5.0 INSPECTION
5.1 INSPECTIoN FrEQUENCY: The Concrete Bolt Anchor must be inspected at the intervals defined in Section 1. Inspection
procedures are described in the "Inspection and Maintenance Log" (Table 2). Inspect all other components of the Fall
Protection System per the frequencies and procedures defined in the manufacturer's instructions.
5.2 DEFECTS: If inspection reveals an unsafe or defective condition, remove the Concrete Bolt Anchor from service
immediately and contact 3M regarding replacement or repair. Do not attempt to repair the Fall Arrest System.
;
Authorized Repairs Only: Only 3M or parties authorized in writing my make repairs to this equipment.
5.3 ProDUCT LIFE: The functional life of the Fall Protection System is determined by work conditions and maintenance. As
long as the product passes inspection criteria, it may remain in service.
1 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.
2 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.
