2.0 SYSTEM REQUIREMENTS
2.1 ANCHORAGE: The anchorage structure securing this product must be able to withstand any required loads as permitted by its
Fall Protection system. See Section 4 for more information.
2.2 CAPACITY: The user capacity of a complete Fall Protection system is limited by its lowest rated maximum capacity component.
For example, if your connecting subsystem has a capacity that is less than your harness, you must comply with the capacity
requirements of your connecting subsystem. See the manufacturer instructions for each component of your system for capacity
requirements.
2.3 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: high
heat, chemicals, corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp
edges, or overhead materials that may fall and contact the user or equipment. Contact 3M Technical Services for further
clarication.
2.4 LIFELINE HAZARDS: Ensure the lifeline is kept free from all hazards including, but not limited to: entanglement with
users, other workers, moving machinery, other surrounding objects, or impact from overhead objects that could fall onto
the lifeline or users.
2.5 COMPONENT COMPATIBILITY: 3M equipment is designed for use with 3M equipment. Use with non-3M equipment
must be approved by a Competent Person. Substitutions made with non-approved equipment may jeopardize equipment
compatibility and may aect the safety and reliability of your Fall Protection system. Read and follow all instructions and
warnings for all equipment prior to use.
2.6 CONNECTOR COMPATIBILITY: Connectors are compatible with connecting elements when the size and shape of either

applicable standards. Connectors must be fully closed and locked during use.
3M Connectors (snap hooks and carabiners) are designed to be used only as specied in each instruction manual. Ensure
connectors are compatible with the system components to which they are connected. Do not use equipment that is non-
compatible. Use of non-compatible components may cause the connector to unintentionally disengage (see Figure 3). If
the connecting element to which a connector attaches is undersized or irregular in shape, a situation could occur where
the connecting element applies a force to the gate of the connector (A). This force could then cause the gate to open (B),
disengaging the connector from the connecting element (C).
6
2.7 MAKING CONNECTIONS: All connections must be compatible in size, shape, and strength. See Figure 4 for examples of
inappropriate connections. Do not attach 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 D-Rings or
other connecting elements, unless the snap hook has a gate strength of 16 kN (3,600 lbf) or greater.
C. In a false engagement, where size or shape of the connector or connecting element is not compatible and, without
visual conrmation, would seem to be fully engaged.
D. To each other.
E. Directly to harness webbing, lanyard leg material, or tie-back material unless such a connection is explicitly allowed
for by the manufacturer instructions.
F. To any object whose size or shape does not allow the connector to fully close and lock, or that could cause connector
roll-out.
G. In a manner that does not allow the connector to align properly while under load.
