7.0 PRODUCT SPECIFIC APPLICATIONS
Personal Fall Arrest: Safewaze Vertical Lifelines 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 a VLL. Only one fall arrester is to be attached to the VLL at any given time. Avoid sharp and/or abrasive edges. If contact with an
abrasive surface is unavoidable, proper rope 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. The maximum allowable free fall is 6 ft., with the maximum combined length of the fall arrester, lanyard extension, and
D-ring being 36 inches.
8.0 LIMITATIONS
Fall Clearance: There must be sufficient clearance below the anchorage connector to arrest a fall before the user strikes the ground or an obstruction. When
calculating fall clearance, account for a MINIMUM 2' safety factor, deceleration distance, user height, length of lanyard/SRL, and all other applicable factors
(Figure 1). Lanyards used with Safewaze rope grabs must be shock absorbing and no more than 36" in length.
For all applications: Worker weight capacity range is 130-310 lbs (including all clothing, tools, and equipment)
Swing Falls: Prior to installation or use, make considerations for eliminating or minimizing all swing fall hazards. Swing falls occur when the anchor is not directly
above the location where a fall occurs. Always work as close to the anchor point as possible. Swing falls significantly increase the likelihood of serious injury or
death in the event of a fall (Figure 2).
WARNING: AVOID SWING FALL HAZARDS ENCOUNTERED WHEN ANCHORAGE IS NOT DIRECTLY OVERHEAD.
9.0 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). Connectors must be compatible with the anchorage or other system components (Figure 3). Do not use equipment that is not
compatible. Non- compatible connectors may unintentionally disengage (Figure 3). 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.
