connectors may unintentionally disengage. Connectors must be compatible in size,
shape, and strength. Self-closing, self-locking snap hooks and carabiners are required by
ANSI and OSHA.
3.2 Compatibility of Components: Equipment is designed for use with approved
components and subsystems only. Substitutions or replacements may only be made by
a competent person.
3.3 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. Visually ensure all connectors are fully closed and locked. Connectors
(snap hooks and carabiners) are designed to be used only as specified in each product's
user's instructions. See Figure 3.
DO NOT:
•
attach multiple snap hooks or carabiners to an anchorage.
•
attach snap hooks or carabiners in a manner that may result in the gate being
loaded.
•
allow a false engagement, where features that protrude from the snap hook
or carabiner catch on the anchor.
•
attach snap hooks or carabiners to each other.
•
attach snap hooks or carabiners to webbing or rope lanyard or tie-back (unless
the manufacturer's instructions for both the lanyard and connector specifically
allows such a connection).
•
attach snap hooks or carabiners 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.

3.5 100% Tie-Off Applications: Y-leg configurations are designed to provide the user
100% tie-off capability. When using Y-leg lanyard configurations, take appropriate
caution when moving from one anchorage to another. At least one leg must be
anchored at all times. Two-point tie off should only be maintained for the limited time
needed to make the transition to the new anchor point. Attach the unused lanyard legs
