WARNING
Be sure to read, understand, and follow all instructions and warnings in this
manual.
Any misuse could result in serious injury or death.
Application
3.1 Purpose:
The FallTech Ironworkers Bolt-On D-Ring Anchor is designed to be attached to
steel structure with a user-supplied fastener as part of Personal Fall Arrest
System, restraint, or work positioning system.
Ironworkers Anchors may be attached overhead, horizontally, or along the
walking-working surface as approved by the Competent Person and/or Qualified
Person.
3.2 Personal Fall Arrest System:
A PFAS is typically composed of an anchorage and a FBH, with an energy
absorbing connecting device, i.e., a EAL, an SRD, or a Fall Arrester
Connecting Subsystem (FACSS), attached to the dorsal D-ring of properly fitted
and adjusted FBH. All uses and applications of a FBH with this equipment
requires the FBH to be properly fitted and adjusted to the user. Failure to
properly fit the FBH to the user could result in serious injury or death.
3.3 Application Limits:
Care should be taken to understand the capacity of the system, anchorage
strength requirements, total allowable free fall, and the requirements of how
the user’s PFAS deploys during a fall event. The longer the freefall, the
greater the energy in the system, which will result in more significant
clearance requirements and impact forces on the body. Take action to avoid
sharp edges, abrasive surfaces, and thermal, electrical, and chemical hazards.
Installation of the anchor below the full body harness (FBH) dorsal D-ring
requires the use of a PFAS designed for extended free fall scenarios. Minimum
service temperature is -40°F (-40°C).
3.5 Approved Applications:
Below are applications for which the Ironworkers Anchor are specifically
suited. This list is not allinclusive, but is intended to anticipate the
common applications in which this product may be used.
3.5.1 Personal Fall Arrest:
The Ironworkers Anchor is designed to be used as single person anchor point
for a personal fall arrest system. Use with horizontal lifelines is
prohibited.
3.5.2 Work Positioning:
The Ironworkers Anchor may be used as a component of a work positioning system
to support the user at a work position. Work positioning systems typically
include an FBH with integrated side D-rings, a body belt, and a positioning
lanyard. A back up PFAS is required when the user is exposed to a free fall of
2 ft (1.8 m) or more.
3.5.3 Restraint:
The Ironworkers Anchor may be used as a component of a restraint system to
prevent the user from reaching a fall hazard. Restraint systems typically
include a full body harness containing a body belt and a lanyard or restraint
line.
3.5.4 Horizontal Lifelines:
The Ironworkers Anchor is suitable for use in any application where a
horizontal lifeline has been installed under the guidance of a Qualified
Person, and where the freefall distance does note exceed 6 ft (1.8 m). The
horizontal lifeline system shall limit maximum arrest forces loading the
Ironworkers Anchor to 2,500 lbf (11.1 kN).
3.6 Approved Load Directions:
The Ironworkers Anchor may be attached in a variety of orientations depending
on the application at hand. Figure 2 below illustrates the approved load
directions of the Ironworkers Anchor.
Figure 2 – Approved Load Directions
System Requirements
4.1 Capacity:
The FallTech Ironworkers Bolt-On D-Ring Anchor discussed in this manual is
rated for a maximum total combined (clothing, tools, etc.) user weight of 425
lbs (192.8 kg). To comply with ANSI Z359, total worker weight must be 130 to
310 lbs (59 to 140.6 kg). Heavyweight users must wear an appropriately rated
connecting device or self-retracting lifeline. After a fall event, suspension
trauma may rapidly develop. Users are advised to deploy suspension trauma
relief equipment as soon as possible after a fall event.
4.2 Compatibility of Connectors:
Connectors are considered to be compatible with connecting elements when they
have been designed to work together in such a way that their sizes and shapes
do not cause their gate mechanisms to open inadvertently regardless of how
they become oriented. Contact FallTech® if you have any questions about
compatibility. Connectors must be compatible with the anchorage or other
system components.
Do not use equipment that is not compatible. Non-compatible connectors may
unintentionally disengage Connectors must be compatible in size, shape, and
strength. Substitutions or replacements made with non-OSHA 1926 compliant
components or subsystems may jeopardize compatibility of equipment and may
affect the safety and reliability of the complete system.
4.3 Making Connections:
Only use self-locking connectors with this equipment. Only use connectors that
are suitable to each application. Ensure all connections are compatible in
size, shape, and strength. Do not use equipment that is not compatible.
Visually ensure all connectors are fully closed and locked. Connectors (snap
hooks, rebar hooks, and carabiners) are designed for use only as specified in
this manual.
Figure 3 – Non-Compatible Connections
A| Never connect two active components (snap hooks or carabiners) to each
other.
---|---
B| Never connect two active components (snap hooks or carabiners) to a single
D-ring at the same time.
C| Never connect in a way that would produce a condition of loading on the
gate.
D| Never attach to a object in a manner whereby the gate (of the snap hook or
carabiner) would be prevented from fully closing and locking. Always guard
against false connections by visually inspecting for closure and lock.
E| Never attach explicitly to a constituent subcomponent (webbing, cable or
rope) unless specifically provided for by the manufacturer’s instructions for
both subcomponents (snap hook or carabiner and webbing, cable or rope).
F| Never attach in a manner where an element of the connector (gate or release
lever) may become caught on the anchor thereby producing additional risk of
false engagement.
G| Never attach a spreader snap hook to two side/positioning D-rings in a
manner whereby the D-rings
will engage the gates; the gates on a spreader must always be facing away from
the D-rings during work positioning.
4.4 Personal Fall Arrest System:
PFAS used with this equipment must meet OSHA requirements. A full body harness
must be worn when this equipment is used as a component of a PFAS. As required
by OSHA, the personal fall arrest system must be able to arrest the user’s
fall with a maximum arresting force (MAF) of 1,800 lbs (8 kN),
and limit the free fall to 6 ft (1.8 m).
4.5 Personal Fall Arrest System Anchorage Strength:
PFAS Anchorage Strength: An anchorage selected for PFAS must have a strength
able to sustain a static load applied in the direction permitted by the PFAS
of at least:
a. Two times the maximum arrest force permitted when certification exists, or
b. 5,000 lbs. (22.2 kN) in the absence of certification.
Select an anchorage location carefully. Consider structural strength,
obstructions in the fall path, and swing fall hazards. In certain situations,
the qualified person can determine that a given structure is able to withstand
the applied MAF of the PFAS with a safety factor of at least two.
Installation and Use
WARNING
Do not alter or intentionally misuse this equipment. Consult FallTech® when
using this equipment in combination with components or subsystems other than
those described in this manual. All components or subsystems used with the
anchors discussed in this manual must be in compliance with OSHA.
Take action to avoid sharp and/or abrasive surfaces and edges when possible.
5.1. Plan the Personal Fall Arrest System (PFAS):
Examine the work area and take action to address hazards. Falls are a serious
hazard when working at height. Training and equipment are the tools of fall
hazard management. There are several closely related facets of fall hazard
management with a PFAS;
- Anchorage
- Minimum Required Fall Clearance (MRFC)
- Swing Fall and Expanded Work Zone
- Overhead (above the FBH D-ring) Anchorage
- Non-overhead (below the FBH D-ring) Anchorage
- Rescue Plan
5.2 Minimum Required Fall Clearance:
The MRFC is the minimum distance a user needs between himself and the nearest
obstruction (or ground) below the walking/working surface to avoid serious
injury or death in case of a fall event.
The user of this equipment must determine the MRFC for units discussed in this
manual to ensure adequate clearance exists in the fall path. Variables
discussed in this manual include the height of the anchor point relative to
the user’s FBH D-ring, i.e., overhead, see the user manual of your specific
connecting device.
5.3 Pre-Use Inspection:
FallTech requires that the following steps be taken during each inspection
prior to each use of this product.
- Inspect the Ironworkers Bolt-On D-Ring Anchor and user-supplied fastener thoroughly for damage. Inspect all metal parts for cracks, bends, sharp edges, burrs, corrosion, or deformation of any kind.
- Inspect all parts for surface contamination which may inhibit the operation of mechanical parts
- Inspect the labels. All labels must be present and fully legible.
- Inspect each system component or subsystem according to the associated manufacturer’s instructions.
- Remove from service any system component or subsystems that fails inspection.
5.4 Anchorage Location Selection:
Select a suitable anchor location as determined by a Competent Person; see
Section 3.5 and 4.5.
Anchorage hole size in steel structure shall not exceed 1.5” (38 mm).
5.5 Fastener Selection:
FallTech qualified the Ironworkers Anchor to ANSI Z359.18 using 3/4” Grade 8
bolts/nuts and 3/4” ASTM A325 bolts/nuts. Therefore, both fastener
specifications are acceptable for use without additional review by Competent
Person or Qualified Person. Alternate fastener specifications are suitable for
use as approved by the Competent Person or Qualified Person that meet the
minimum 5,000 lbf requirements noted in Section 3.5 and 4.5.
5.6 Installation Instructions:
- Select an appropriate anchorage location.
- Select an appropriate fastener to accommodate steel structure thickness. For bolt and nut connections, bolt length shall be such that there will be a minimum of two full threads exposed after the nut is secured. D-ring Anchor Hole is designed for 3/4” diameter fasteners.
- Ensure the anchorage hole location has sufficient clearance to place and tighten the fastener.
- Orient the D-ring to ensure that the predicted load direction is in line with the major axis of the D-ring. See Figure 2. Do not cross load the D-ring. Avoid orientations that cross load or transversely load connectors.
- Tighten the fastener to manufacturer’s specifications or as determined by the Qualified Person.
- Inspect anchorage connection before connecting PFAS with a compatible connector.
