PRODUCT SPECIFIC APPLICATIONS
Purpose:
The Safewaze D-ring Extender is designed to be used as part of a Personal
Fall Arrest System (PFAS).
- A competent person shall train users on this equipment in accordance
with OSHA and ANSI.
- Never exceed a free fall distance of 6 ft. A free fall of more than 6 ft
could cause excessive arrest forces that could result in serious injury or
death.
- The Safewaze D-ring Extender has a maximum capacity of ANSI
310 lbs including any tools, clothing, accessories, etc..., OSHA 420 lbs,
unless otherwise rated by Safewaze.
- All Safewaze D-ring extenders must IMMEDIATELY be removed from
service if subjected to fall arrest forces.
- Safewaze D-ring extenders shall be inspected by the end user prior to
each usage and by a Competent Person other than the user at least
annually. These inspections shall be documented.

Fall Clearance:
There must be sufficient clearance below the anchorage connector to
arrest a fallbefore the user strikes the ground or an obstruction. When calculating fall
clearance, account for a MINIMUM 2’ safety factor, deceleration distance, user height,
length of Lanyard/SRL, and all other applicable factors. (See Figure 1)
NOTE: THE USE OF A SAFEWAZE D-RING EXTENDER CAN INCREASE FALL
CLEARANCE. USER MUST ALLOW FOR THE LENGTH OF D-RING EXTENDER

Swing Falls:
Prior to installation or use, make considerations for eliminating or
minimizing all swing fall hazards. Swing falls occur when the anchor is not directly
above the location where a fall occurs. Always work as close to in line with the anchor
point as possible. Swing falls significantly increase the likelihood of serious injury or
death in the even of a fall. (See Figure 2)

COMPATIBILITY OF CONNECTORS
Connectors are 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 inadvertently open regardless of how they become oriented.
Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least
5,000 lbs. (22.2 kN). Connectors must be compatible with the anchorage or other
system components (See Figure 4).
Do not use equipment that is not compatible
.
Non-compatible connectors may unintentionally disengage (See Figure 3). Connectors
must be compatible in size, shape, and strength. Self-locking snap hooks and
carabiners are required by ANSI Z359 and OSHA guidelines. Contact Safewaze if you
have any questions about compatibility.

NOTE:
SOME SPECIALITY CONNECTORS HAVE ADDITIONAL

MAKING CONNECTIONS
Snap hooks and carabiners used with this equipment must be double locking and/
or twist lock. Ensure all connections are compatible in size, shape and strength. Do
not use equipment that is not compatible. Ensure all connectors are fully closed and
locked.
Safewaze connectors (snap hooks and carabiners) are designed to be used only
as specified in each product’s user’s instructions. See figure 4
for examples of
inappropriate connections. Do not connect snap hooks and carabiners:
•
To a D-ring to which another connector is attached.
•
In a manner that would result in a load on the gate (with the exception of tie back
hooks).
•
NOTE: Large snap hooks must not be connected to objects which will result in a
load on the gate if the hook twists or rotates. Snap hooks marked with ANSI Z359.12
and are equipped with a 3,600 lb (16 kN) gate. Check the marking on your snap
hook to verify its compatibility.
Using a connector that is undersized or irregular in shape (1) to connect a snap hook
or carabiner could allow the connector to force open the gate of the snap hook or
carabiner. When force is applied, the gate of the hook or carabiner presses against
the non-compliant part (2) and forces open the gate (3). This allows the snap hook or
carabiner to disengage (4) from the connection point.
