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.
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 (See Figure 1). Lanyards used with Safewaze rope grabs must be shock absorbing and no more than 36” in length.
Calculate Minimum Required Fall Clearance
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 in line with the anchor point as possible. Swing falls significantly increase
the likelihood of serious injury or death in the event of a fall. (See Figure 2)
For all applications: worker weight capacity range
(including all clothing, tools, and equipment) is 130-310 lbs
