2.0 SYSTEM
REQUIREMENTS
2.1 COMPATIBILITY OF COMPONENTS:
DBI-SALA equipment
is designed for use with DBI-SALA approved components and
subsystems only. Substitutions or replacements made with non-
approved components or subsystems may jeopardize compatibility
of equipment and may effect the safety and reliability of the
complete system.
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 2). 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 use self-locking snap hooks and
carabiners with this equipment. Only use connectors that are
suitable to each application. 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.
Figure 2 - Unintentional Disengagement (Roll-out)
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.
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.
