2.2 COMPATIBILITY OF CONNECTORS:
Connectors are considered
to be 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. Contact DBI-SALA if you
have any questions about compatibility.
Connectors (hooks, carabiners, and D-rings) must be capable
of supporting at least 5,000 lbs. (22.2kN). Connectors must be
compatible with the anchorage or other system components. Do not
use equipment that is not compatible. Non-compatible connectors
may unintentionally disengage. See Figure 6. Connectors must be
compatible in size, shape, and strength. Self locking snap hooks
and carabiners are required by ANSI Z359.1 and OSHA.
2.3 MAKING CONNECTIONS:
Only self-locking snap hooks and/or
carabiners shall be used with this equipment. Ensure all connectors
are fully closed and locked and compatible.
DBI-SALA connectors (snap hooks and carabiners) are designed to
be used only as specified in each product’s user instructions. See
Figure 3 for inappropriate connections. DBI-SALA snap hooks and
carabiners should not be connected:
A.
To a D-ring which another connector is already attached.
B.
In a manner that would result in a load on the gate.
If the connecting element that a snap hook (shown) or carabiner attaches to is
undersized or irregular in shape, a situation could occur where the connecting
element applies a force to the gate of the snap hook or carabiner. This force
may cause the gate (of either a self-locking or a non-locking snap hook) to
open, allowing the snap hook or carabiner to disengage from the connecting
point. For ANSI Z359.1-2007 compliant hooks, there are no restrictions on the
size or shape of the mating connector provided the snap hook is free to align
with the applied load as intended.
1. Force is applied to
the snap hook.
2. The gate presses against
the connecting ring.
3. The gate opens
allowing the snap hook
to slip off.
