2.0 SYSTEM REQUIREMENTS
2.1 RESCUE PLAN: When using this equipment and connecting subsystem(s), the employer must have a rescue plan and
the means at hand to implement and communicate that plan to users, authorized persons
3
, and rescuers
4
. A trained, on-
site rescue team is recommended. Team members should be provided with the equipment and techniques to perform a
successful rescue. Training should be provided on a periodic basis to ensure rescuer prociency.
2.2 INSPECTION FREQUENCY:
The Connected Order Picker System shall be inspected by the authorized person
5
or rescuer
6
before each use (see Table 3). Additionally, inspections shall be conducted by a Competent Person other than the user.
Extreme working conditions (harsh environment, prolonged use, etc.) may necessitate more frequent Competent Person
inspections. The Competent Person shall use the Inspection Schedule (Table 2) to determine appropriate inspection
intervals.
Inspection procedures are described in the Inspection & Maintenance Log (Table 3). Results of the Competent
Person inspection should be recorded in the Inspection and Maintenance Log.
2.3 SRD OPERATION: Normal operation of the SRD 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.
2.4 COMPONENT COMPATIBILITY: 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 the safety and reliability of the complete system.
2.5 CONNECTOR COMPATIBILITY: 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 lbs. (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. 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).
Self-locking snap hooks and carabiners are required by ANSI Z359 and OSHA.
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 specied 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 complies is equipped with a 3,600 lb (16 kN) gate. Check the marking on your snap hook to verify that it
is appropriate for your application.
C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor, and
without visual conrmation 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 specically 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.
