2.0 SYSTEM REQUIREMENTS
2.1 FALL PROTECTION AND RESCUE PLAN: The employer must have a Fall Protection and Rescue Plan in place that meets
ANSI Z359.2 Minimum Requirements for a Comprehensive Managed Fall Protection Program. The plan should provide
guidelines and requirements for an employer's managed fall protection program, including policies, duties and training;
fall protection procedures; eliminating and controlling fall hazards; rescue procedures; incident investigations; and
evaluating program effectiveness.
2.2 NORMAL OPERATIONS: Normal operation will allow the lifeline to extend and retract with no hesitation or slack as
the worker moves at normal speeds. If a fall occurs, a speed sensing brake system will activate, stopping the fall and
absorbing much of the energy created. Sudden or quick movements should be avoided during normal work operation, as
this may cause the SRD to lock up. For falls which occur near the end of the lifeline travel, a reserve lifeline system or
Energy Absorber has been incorporated to reduce the fall arrest forces.
2.3 BODY SUPPORT: A Full Body Harness must be used with the Self-Retracting Device. The harness connection point must
be above the user's center of gravity. A body belt is not authorized for use with the Self-Retracting Device. If a fall occurs
when using a body belt it may cause unintentional release or physical trauma from improper body support.
2.4 COMPATIBILITY OF COMPONENTS: Unless otherwise noted, 3M equipment is designed for use with 3M 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.
2.5 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 3M if you have any questions about compatibility.
Connectors (hooks, carabiners, and D-rings) must be capable of supporting at least 5,000 lb. (22.2 kN). 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 5). Connectors must be compatible in size, shape,
and strength. Self-locking snap hooks and carabiners are required. If the connecting element to which a snap hook or
carabiner attaches 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 (A). This force may cause the gate to open (B), allowing the snap hook or
carabiner to disengage from the connecting point (C).
2.6 MAKING CONNECTIONS: Snap hooks and carabiners used with this equipment must be self-locking. 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. 3M connectors (snap hooks and carabiners) are designed to be used only as
specified in each product's user's instructions. See Figure 6 for examples of inappropriate connections. Do not connect
snap hooks and carabiners:
A. To a D-ring to which another connector is attached.
B. In a manner that would result in a load on the gate. Large throat 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, unless the
snap hook is equipped with a 3,600 lbf (16 kN) gate.
C. In a false engagement, where size or shape of the mating connectors are not compatible and, without visual
confirmation, the connectors seem fully engaged.
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 allows 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.
G. In a manner that does not allow the connector to align properly while under load.
