Environmental Hazards:
Use of this equipment in areas with environmental hazards may require
additional precautions to prevent injury to the user or damage to the equipment. Hazards may include, but
are not limited to; heat, chemicals, corrosive environments, high voltage power lines, gases, moving
machinery, and sharp edges.
Compatibility of Components:
Unless otherwise noted, Palmer Safety equipment is designed for use with
Palmer Safety approved components and subsystems only. Substitutions or replacements made with non-
approved components or subsystems may jeopardize compatibility of equipment and may affect safety and
reliability of the complete system.
Palmer Safety connectors (snap hooks and carabiners) are designed to be used only as specified in each
product's user's instructions. See Figure below for illustration of the inappropriate connections stated
below.
4. RESTRICTIONS REGARDING MAKING CONNECTIONS:
Do not make connections where the hook locking mechanism can come into contact with a structural
member or other equipment and potentially release the hook.
Do not connect a snap hook into a loop or thimble of a wire rope.

Never connect two active components (snap hooks or carabiners) to a
single D-ring at the same time.
Never connect in a way that would produce a condition of loading on the
gate.
Never attach in a manner where an element of the connector (gate or
release lever) may become caught on the anchor thereby producing
additional risk of false engagement.
Never connect two active components (snap hooks or carabiners) to each
other.
Never attach explicitly to a constituent subcomponent (webbing, cable or
rope) unless specifically provided for by the manufacturer’s instructions
for both subcomponents (snap hook or carabiners and webbing, cable or
rope).
Never attach to a object in a manner whereby the gate (of the snap hook or
carabiner) would be prevented from fully closing and locking. Always
guard against false connections by visually inspecting for closure and lock.

Note:
Other than 3,600 lbs. gated hooks, large throat opening snap hooks should not be connected to
standard size D-rings. 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.
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. Connectors (hooks,
carabiners, and D-rings) must be capable of supporting at least 5,000 lbs. Connectors must be compatible
with the anchorage or other system components. Do not use equipment that is not compatible. Non-com-
patible connectors may unintentionally disengage (see Figure 6). Connectors must be compatible in size,
shape, and strength. Self-locking connectors are required by ANSI Z359.11 and OSHA.
3. MAKING CONNECTIONS:
Use only self-locking connectors 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.
