7.0 COMPATIBILITY OF COMPONENTS
Unless otherwise noted, Safewaze equipment is designed for, and tested with, associated Safewaze components or systems.
IMPORTANT: If substitutions or replacements are made to the system, ensure all components meet the applicable
ANSI requirements. Read and follow manufacturer's instructions for all components and subsystems in your
personal fall arrest system. Not following this guidance may jeopardize compatibility of equipment, and possibly affect
the safety and reliability of the overall system.
8.0 COMPATIBILITY OF CONNECTORS
Connectors are 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. (22.2 kN). Do not use equipment that is not compatible. Non-compatible connectors may unintentionally disengage (Figure 3). Connectors
must be compatible with the anchorage or other system components. Connectors must be compatible in size, shape, and strength. Self-locking snap hooks and
carabiners are required by ANSI Z359 and OSHA guidelines. Contact Safewaze if you have any questions about compatibility.
NOTE: SOME SPECIALTY CONNECTORS HAVE ADDITIONAL REQUIREMENTS. CONTACT SAFEWAZE WITH QUESTIONS.
1 - Non-compliant part
Using a connector that is undersized or irregular in shape (1) to connect a snap hook or carabiner could allow the connector to force open the gate of the snap
hook or carabiner. When force is applied, the gate of the hook or carabiner presses against the non-compliant part (2) and forces open the gate (3). This allows
the snap hook or carabiner to disengage (4) from the connection point.
9.0 MAKING CONNECTIONS
Snap hooks and carabiners used with this equipment must be double locking and/or twist lock. 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.
Safewaze connectors (hooks, carabiners, and D-rings) are designed to be used only as specified in each product's user instructions. See Figure 4 for examples of
inappropriate connections. Do not connect snap hooks and carabiners:
•
To a D-ring to which another connector is attached.
•
In a manner that would result in a load on the gate (with the exception of tie-back hooks). NOTE: Large snap hooks must not be connected to objects which
will result in a load on the gate if the hook twists or rotates, unless the snap hook complies with ANSI Z359.12 and is equipped with a 3,600 lb (16 kN) gate.
Check the marking on your snap hook to verify its compatibility.
•
In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor, and without visual confirmation seems to be fully
engaged to the anchor point.
•
To each other.
•
To any object which is shaped or sized in a way that the snap hook or carabiner will not close and lock, or that roll-out could occur.
•
In a manner that does not allow the connector to align properly while under load.
10.0 APPLICATION LIMITS
Precautions should be taken in the design and installation of a PFAS in order to avoid hazards such as thermal, chemical, or electrical hazards. Avoid moving
machinery, sharp and/or abrasive edges, and any other hazard that could damage or degrade components of the PFAS.
IMPORTANT:
WARNING:
FIGURE 3 - UNINTENTIONAL DISENGAGEMENT
2 - gate presses
against
non-complaint part
FIGURE 4 - INAPPROPRIATE CONNECTIONS
The components of a PFAS used in conjunction with the Safewaze Rescue & Descent System should meet the
requirements of the ANSI Z359 Fall Protection Code.
Contact Safewaze if you have questions regarding compatibility of this equipment. Do not alter or misuse this
equipment. Some subsystem components could affect the performance and the operation of this equipment. Do not
connect this product to moving machinery, or hazards that include chemical, electrical, or gaseous characteristics.
Failure to comply with this warning could result in serious injury or death.
