Fall Clearance:
Figure 1 Illustrates a Fall Clearance Calculation. Fall Clearance (FC) is the total combined values of Free Fall (FF),
Deceleration Distance (DD), and a Safety Factor (SF). Safety Factor calculations may differ by manufacturer, but for the purposes of this manual,
the Safety Factor is calculated at 2 ft. The Safety Factor includes D-ring shift and Harness Stretch.
Table 5 in this manual indicates the Minimum Fall Clearances when
Latitude / Latitude Pro SRL-Ps
are anchored overhead. For falls from a
kneeling or crouched position an additional 3 ft. (1 m) of Fall Clearance is required. If a Swing Fall Hazard exists, the total vertical fall distance
will be greater than if the user had fallen directly under the anchor point. Section 10 and Table 6 in this manual provide information regarding
Swing Fall hazards and additional Fall Clearance Requirements. The use of a D-ring extender can increase fall clearance. The user must allow
for the length of the D-ring extender when calculating fall clearance.
•
Sharp Edges:
Safewaze
Class 2 SRLs
are designed for use in both Overhead and Leading Edge Environments. Should a specific work area have
extremely sharp edge(s) that may come into contact with the lifeline constituent of the SRL, a
Class 2 SRL
is required.
•
Hazards:
Extra precautions should be taken if this equipment is used in an environment where hazards exist. Hazards can include but are not limited to:
moving machinery, high voltage equipment or power lines, caustic chemicals, corrosive environments, toxic or explosive gases, or high heat. Avoid working in
an area where overhead equipment or personnel could fall and contact the user, fall protection equipment, or the lifeline. Areas where the user’s lifeline may
cross or tangle with the lifeline of another user should be avoided. Do not allow the lifeline to pass under arms or between the user’s legs.
7.0 PURPOSE
Self-Retracting Lifelines are used as part of a PFAS. Safewaze SRLs are designed to safely arrest the user in a fall from height, while minimizing forces
associated with what can be an extremely violent event. Safewaze SRLs are authorized for use with Horizontal Lifeline Systems but must NEVER be used
as the lifeline constituent of an HLL System. Safewaze Latitude Tie-Back SRL-Ps are designed for use below the Dorsal D-ring, up to a maximum distance of
5’ (1.5 m). Latitude Pro Tie-Back SRL-Ps are designed for use below the Dorsal D-ring, up to a maximum of 2’ (.61 m).

Personal Fall Arrest:
Safewaze Latitude / Latitude Pro Tie-Back SRL-Ps can be used as part of a complete Personal Fall Arrest System (PFAS) for a maximum
of one user. Only one user may be connected to an SRL. Avoid sharp and/or abrasive edges. If contact with an abrasive surface is unavoidable, proper edge
protection must be used. The structure utilized for attachment must be capable of withstanding a load of 5,000 lbs. in all directions permitted by the system.

Actual Arrest Distance (AD):
Table 3 indicates the Actual Arrest Distance (AD) of the Latitude SRL-Ps when anchored directly overhead with 0’ Swing Fall. Testing was performed in four
environmental conditions. The actual arrest distances for the Latitude SRL-Ps indicated in Table 3, may allow a Qualified / Competent Person to determine if
MRFCs can be adjusted based on jobsite conditions and/or environmental factors. A Maximum Allowed Arrest Distance of 42” was used in the MRFC calculations
for Figure 1 and Table 5.
