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.
FIGURE 3 - UNINTENTIONAL DISENGAGEMENT
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.
WARNING: AVOID SWING FALL HAZARDS ENCOUNTERED WHEN ANCHORAGE IS NOT DIRECTLY OVERHEAD

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 as
well as the correct connection of a user to the VLL.
NOTE:
ALWAYS connect shock pack of lanyard to the user's dorsal D-ring! DO NOT connect shock
pack to the rope grab!
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. Hooks supplied with
Safewaze VLLs comply with ANSI Z359.12 and are equipped with a 3,600 lbs. (16 kN) gate. Check the marking on your snap hook to verify its
compatibility.
•
In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor, and without visual confirmation seems to
be fully engaged to the anchor point.
•
To each other.
•
By wrapping the web lifeline around an anchor and securing to lifeline except as allowed for Tie Back models.
•
To any object which is shaped or sized in a way that the snap hook or carabiner will not close and lock, or that roll-out could occur.
•
In a manner that does not allow the connector to align properly while under load.
