3.5 PERSONAL FALL ARREST SYSTEM REQUIREMENTS: PFAS’s used with this roof anchor must meet applicable
OSHA (state and federal) and ANSI requirements (“Compliance in a Can components meet these requirements).
PFAS’s incorporating a full body harness must be capable of arresting a person’s fall with a maximum arresting
force of no greater than 1,800 lbs., and limit the free fall distance to six (6) feet or less. The deceleration distance
for a PFAS must be 42 inches (1.1M) or less. Reference ANSI Z359.1-1992 and OSHA 1926 requirements.
3.6 RESTRAINT SYSTEMS: Restraint systems must meet applicable state and federal requirements. Reference ANSI
A10.14-1991. The “Compliance in a Can” kit is not designed to be used as a restraint system-only for fall arrest.
3.7 FALL CLEARANCE: Should a fall occur, there must be sufficient clearance in the fall area to arrest the fall before
striking the ground or other object(s). The actual clearance required is dependent upon the type of fall arrestor
connecting the subsystem used (i.e. the shock absorbing lanyard/rope grab combination, or a self retracting
lifeline). Refer to instructions included with deceleration device elements when determining minimum clearances.
3.8 SWING FALLS: Swing falls occur when the anchor location is not directly above the point where a fall occurs. The
force of striking an object while swinging can be great and may cause serious injury. Swing falls can be minimized
by working as directly below the anchorage as possible.
3.9 SHARP EDGES: Avoid working where the connecting subsystem (i.e. shock absorbing lanyard, full body harness,
etc.) or other system components will be in contact with, or abrade against unprotected sharp edges. Do not loop
lanyard around small diameter structural members. If working with this equipment near sharp edges is unavoidable,
protection against cutting must be provided by using a heavy pad or other means over the exposed sharp edge.
3.10 RESCUE: Should a fall occur, the employer must have a rescue plan and the means to implement it in place.
3.11 AFTER A FALL: Any equipment which has been subjected to the forces of arresting a fall must be removed from
service immediately and destroyed, or contact PROTECTA for repair or recertification information.
3.12 ANCHOR LOCATION:
Anchor plates (AJ720A)
must be located at
structurally sound points in
accordance with the
previously discussed
system requirements (see
section 2.0). Holes for the
anchor must be at least 4
inches from any free edge.
When more than one
AJ720A Concrete Anchor is
mounted on an anchorage,
they must be separated by
at least 10 inches. See
Figure 2.
NOTE: It is recommended that the holes be drilled and the bolts installed with the anchor plate in place, using the plate
as a guide to keep the drill from wandering.
3.13 INSTALLING THE ANCHOR: Anchor installation requires that holes be drilled into the concrete surface and the
included anchor bolts inserted and affixed: See Figure 3.
STEP 1.
Using a ½ in. carbide drill bit, drill each hole a minimum of 3 ¾ in. deep. Clean out the holes
with a blow-out bulb or compressed air.
STEP 2.
Assemble the washer and nut onto the bolt. Screw the nut onto the bolt until it is flush with the
top of the bolt to protect the threads. Place the bolt through anchor plate and into the hole. Drive the bolt
into the hole until the washer is pressed against the surface of the anchor plate.
STEP 3.
Expand the anchor bolt by tightening the bolt to the installation torque of 55 ft. lbs. Minimum
embedment in concrete: 2¼ in.
