Use on the Ridge – as a PFAS attachment point for an SRD, or a FACSS. See paragraph 2.1.1. Installed on the ridge with lag bolts, it may be loaded in any
direction, as shown in Figure 5A. Placed on the middle of the ridge on a low‐slope roof, mobility is 360°, with access to most areas of the roof, to the limit
of the PFAS device being used for fall protection. On a normal slope roof, mobility is 360°, within the limits of the PFAS device. Be aware of edges and swing
fall hazards, and ensure the connection O‐ring and chain realign properly, without kinks or binding on the chain attachment stud. The anchor may be
installed with lag bolts on the ridge and used as the end connectors for an approved HLL system. See paragraph 2.1.2.
Use on the Field ‐ as a PFAS attachment point for an SRD, or a FACSS. Installation with lag bolts on the field allows the anchor to be loaded at right angles
to the longitudinal axis. Do not work above the anchor if installed on the field. Low‐slope roofs offer more latitude in use. Do not cross over the ridge and
work on the opposite slope. Use caution, remain aware of edges and swing fall hazards. Normal slope roofs are more restricted as the fall hazards are greater.
The anchor may be installed in pairs with lag bolts on the field and used as the end connectors for an approved HLL system. See paragraph 2.1.2.
3. SYSTEM REQUIREMENTS
3.1 Capacity: Limit user weight to 130 – 310 lbs., (59 – 140.6 kg), including clothing, tools, etc. No more than one PFAS may be attached to one anchor at any time.
3.2 Compatibility of Connectors: Connectors are considered 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. ANSI and OSHA require self‐closing, self‐locking snap hooks and carabiners. See Figure 13 in Appendix B for common incorrect connections to avoid.
DO NOT attach rebar hooks to this anchor. A side load on the gate may cause an unintentional disengagement. Use only self‐closing, self‐locking snap
hooks and carabiners.
3.3 Compatibility of Components: Equipment is designed for use with approved components and subsystems only. Substitutions or replacements made
with non‐approved components or subsystems may jeopardize compatibility of equipment and may affect the safety and reliability of the complete system.
3.4 Making Connections: Use only connectors designed for use with this equipment, suitable to each application. Ensure all connections are compatible in
size and strength. Do not use equipment that is not compatible. Visually ensure all connectors are fully closed and locked. Connectors (snap hooks and
carabiners) are designed to be used only as specified in each product's user instructions.
3.5 Personal Fall Arrest System: PFAS used with the chain roof anchor must meet ANSI Z359 requirements and applicable OSHA regulations. An
anchorage selected for PFAS must be 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.
An FBH 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 of 1,800 lbs., and in this application limit free fall to 12 feet or less.
If the maximum free fall distance must be exceeded, the employer must document, based on test data, that the maximum arresting force will not be
exceeded, and the personal fall arrest system will function properly.
3.5.1 Restraint System: An anchorage selected for restraint must be able to support a static load applied in the direction permitted by the system of at least:
a) Two times the foreseeable force when certification exists, or
b) 1,000 lbs. (4.4 kN) in the absence of certification.
An FBH must be worn when this equipment is used as a component of a restraint system. As required by OSHA, the restraint system must prevent the user
from reaching a fall hazard area. Free fall is not permitted.
3.6 Definitions: The following are definitions of terms.
Authorized Person: A person assigned by the employer to perform duties at a location where the person will be exposed to a fall hazard (otherwise
referred to as "user" for the purpose of these instructions).
Certified Anchorage: An anchorage for fall arrest, positioning, restraint, or rescue systems that a qualified person certifies to be capable of supporting the
potential fall forces that could be encountered during a fall or that meet the criteria for a certified anchorage prescribed in this standard.
Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary,
hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
Qualified Person: A person with a recognized degree or professional certificate and with extensive knowledge, training, and experience in the fall protection and
rescue field who is capable of designing, analyzing, evaluating and specifying fall protection and rescue systems to the extent required by this standard.
Rescuer: Person or persons other than the rescue subject acting to perform an assisted rescue by operation of a rescue system.
4. INSTALLATION AND OPERATION
Installation of anchorages must be under the supervision of a competent person trained in their design and use.
NOTE: Approved fall protection may be required during installation of all Anchorage units discussed in this manual.
DO NOT use any anchorage discussed in this manual until the system has been completely installed, inspected, and approved for use by a competent person.
4.1 Fall Clearance Distance: Take action to reduce the danger of falls. Ensure sufficient clearance in the fall area to arrest the fall before striking the
ground or other objects. The actual clearance required is dependent upon the type of connecting subsystem used (SAL, SRD, etc.). Swing fall conditions will
increase the Clear Fall requirement, and HLL systems will require additional fall clearance. Consult the HLL user instructions.
4.2 Swing Fall: Swing falls occur when the anchorage point is not directly above the point where a fall occurs. The total fall distance may be greatly
increased during a swing fall. The force of striking an object in a swing fall may cause serious injury. Minimize swing falls by installing anchors at least six
feet from exposed roof edges and by working as directly below the anchorage point as possible. Move the anchor as required or install additional anchors
no more than 8 feet apart. See Figure 8.
4.3 Installation Requirements: Inspect the anchor before each use according to the inspection procedure detailed in Section 7 of this manual. Consider
conditions and circumstances that could affect user safety. Select a suitable anchor point that will support the strength requirement and minimize free fall
and swing hazards. See Section 3 of this manual for anchorage strength requirements.
The anchor is designed for roof installation on wood frame structures, located along the ridge, or on the field, on top of sheathing, directly over and
attached to a truss or rafter. See Figure 6.
Install the anchor a minimum 6ft. from any exposed edge, and a maximum of 8ft. apart along the ridge or on the field. For hip roofs, install at least one
anchor per hip face. See Figure 7. Anchors may be installed with nails or lag screws. Application, force and load direction dictate fastener choice.
NOTE: Approved fall protection may be required during installation of all anchorage units discussed in this manual.
4.4. Anchor Location: Plan the installation carefully. Determine the location and usage. Location choices are on the ridge, or on the field, as shown in Figure 6.
4.4.1 To Install on the Ridge: Lay the anchor on top of the ridge with the flexible portion centered. Ensure the location is 6ft. from the edge, and that the
anchor is directly over a truss or rafter. Ensure the location will support the anchor load detailed in Section 3 of this manual. See Figure 6.
