FIGURE 1 - 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.
3 - gate opens
2 - gate presses
against
non-complaint
part
4 - parts disengage.

FIGURE 2 - INAPPROPRIATE CONNECTIONS
NOTE:
Large throat snap hooks must not be connected to standard size D-rings or similar objects which will result in a load on the
gate if the hook or D-ring twists or rotates, unless the snap hook complies with ANSI Z359.12 and is equipped with a 3,600 lb (16 kN)
gate. Check the marking on your snap hook to verify that it is appropriate for your application.
•
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.
2.6 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 2)
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, unless the snap hook complies with ANSI Z359.12 and is equipped with a
3,600 lb (16 kN) gate. Check the marking on your snap hook to verify its compatibility.
