6.0 Compatibility Of Connections

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 REQUIREMENTS.
CONTACT SAFEWAZE WITH QUESTIONS.
Non-compliant part
1 -
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.
