IMPORTANT INFORMATION ON LEADING EDGE APPLICATIONS
D-ring extenders are designed to facilitate connecting to the dorsal D-ring of a full body harness (FBH). When used in conjunction with an FBH, the D-ring extender may be used as part of a Personal Fall Arrest System (PFAS).
While working at height exposes users to inherent hazards, the use of any D-ring extender in a leading edge environment exposes users to specific risks associated with extended free-fall, increased fall-forces, and potential contact with sharp or abrasive edges. It should be understood that connecting directly to the dorsal D-ring mitigates the aforementioned specific risks. As previously discussed, this product should only be used with in an approved PFAS and in accordance with the user instruction manual.
It is ultimately the duty of the Competent Person to weigh the associated risks of using a D-ring Extender against the benefit of the convenient attachment point it offers. The risk associated with any part of the energy absorbing element making contact with a sharp edge during a fall-event exists with or without the presence of a D-ring Extender.
2.0 Apejuwe
The FallTech® D-Ring Extender consists of a length of polyester webbing with one or two D-rings on the anchorage end, and a snap hook or a web loop at the attachment end.

IKILO
Do not attach an Energy Absorbing Lanyard (EAL) or other connector to the dorsal D-Ring of a Full Body Harness (FBH) when using a D-Ring extender. Two active connectors on a single D-ring is not in compliance with ANSI requirements or OSHA regulations.
Type A, B and D extenders are designed to allow access to the dorsal D-Ring of the FBH without removing the harness. By extending the D-ring, users can connect to an overhead SRL. Type B and C allow the transfer of anchorage connection between deceleration devices while maintaining 100% tie-off.
ṢE ṢE attach a EAL/SRL or other connectors to the user’s dorsal D-ring while this product is in use.
3.1.1 Fall Restraint:
The D-ring extender, when installed by a Competent Person, may be used in restraint applications, to prevent the user from reaching a fall hazard. No free fall is permitted.
3.1.2 D-Ring Extender for Fall Arrest Application:
The D-ring extender may be used as part of a Personal Fall Arrest System (PFAS). A PFAS will typically include an anchorage, a Full Body Harness (FBH) and a deceleration device such as an Energy Absorbing Lanyard (EAL), a Self-Retracting Lifeline (SRL), or a Vertical Lifeline (VLL) when used with a rope grab/EAL.
D-Ring Extenders can facilitate connection to an anchorage by providing some extra length to make it easier to connect the dorsal D-Ring of the FBH to the deceleration device and provide 100% tie-off while in transition between deceleration devices. Maximum permissible free fall is six feet.

NOTE: Use of an extender will increase the users potential fall distance. The user must be sure the increased total length of a lanyard is accounted for in calculating fall clearance distances, including swing fall. Be aware that when using an SRL, there may be additional fall clearance required depending on anchor point location. If unsure, consult a Competent Person.
5.3 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 edges and by working as directly below the anchorage point as possible. Consult the equipment manufacturer’s user instructions. See Figure 5.
