2. Connection Compatibility Limitations
All equipment must be coupled only to compatible connectors that are suitable to your application. Ensure all
connections are compatible in size, shape and strength. Ensure all connectors are fully closed and locked. Prohibit the
use of snap hooks to engage to objects unless the following requirements are met:
 It must be a locking type snap hook.
 It must be explicitly designed for such a connection. “Designed for” means that the manufacturer of the snap hook
specifically created the snap hook to be used to connect to the equipment in question.
Use of a non-locking snap hook can result in rollout*. Snap hooks and carabiners are designed to be used only as
specified in each product’s user instructions. See as following shown for inappropriate connections.
Avoid the following type of connections:
 Connection of two (or more) snap hooks/rebar hooks or carabiners to one D-ring.
 Connection of a snap hook/rebar hook back to its integral lanyard.
 Direct connection of a snap hook/rebar hook to horizontal lifeline.
 Connection in a manner that results in a load on the gate.
 False engagement connections, where protruding features of the snap hook/rebar hook or carabiner may catch on
the anchor and seem to be fully engaged to the anchor point. Always confirm engagement.
 Connection to snap hooks or carabiners.
 Do not connect a snap hook/rebar hook into a loop or thimble of a wire rope or attach in any way to a slack wire
rope.
 Direct connection to webbing lanyard, webbing loop, rope lanyard or tie-back. (Unless the manufacturer’s
instructions for both the lanyard and connector specifically allow such a connection.)
 Connection of a snap hook to a D-ring, rebar or other connection point of improper dimensions in relation to the
snap hook dimensions or configurations that could cause the snap hook keeper to be depressed by a turning
motion of the snap hook, or such that snap hook or carabiner will not fully close and lock, or that roll-out could
occur.
 Snap hook/rebar hook must be free to align with applied load as intended.
 Carabiner may be connected to a loop or ring connector already occupied by a choker style connector. This type of
connection is prohibited for snap hooks/rebar hooks.
* Rollout: A process by which a snap hook or carabiner unintentionally disengages from another connector or object to which
it is coupled.
