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.

NOTE: Large throat opening snap hooks should 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. Large throat snap hooks are designed for use on fixed

structural elements such as rebar or cross members that are not shaped in a way that can capture the gate of the hook.

C. 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.

D. To each other.

E. Directly to webbing or rope

lanyard or tie-back (unless the

manufacturer's instructions for

both the lanyard and connector

specifically allow such a

connection).

F. To any object which is shaped or

dimensioned such that the snap

hook or carabiner will not close and lock, or that roll-out could occur.

2.4 ANCHORAGE STRUCTURE: The anchorage structure must be rigid and capable of supporting at least 2,800 lbs.

(12.4 kN) along the axis of the horizontal lifeline. Anchorages must also support at least 2,800 lbs. (12.5 kn) applied

in all potential directions of fall arrest that are perpendicular to the axis of the horizontal lifeline. See Figure 5.

2.5 CONNECTING SUBSYSTEM: The connecting subsystem is the portion of the personal fall arrest system that

connects the horizontal lifeline subsystem to the harness fall arrest attachment element. A DBI/SALA Force 2

Energy Absorbing Lanyard must be used as the connecting subsystem with the Vacuum Anchor Horizontal Lifeline.

3.0 OPERATION AND USE

WARNING: Do not alter or intentionally misuse this equipment. Consult DBI/SALA when using this equipment in

combination with components or subsystems other than those described in this manual. Some subsystem and component

combinations may interfere with the operation of this equipment. Use caution when using this equipment around moving

machinery, electrical hazards, chemical hazards, and sharp edges.

2. The gate presses against

the connecting ring.

3. The gate opens allowing the

snap hook to slip off.
