WARNING: Consult your doctor if there is reason to doubt your fitness to safely absorb the shock from a fall arrest. Age
and fitness seriously affect a worker's ability to withstand falls. Pregnant women or minors must not use DBI/SALA self
retracting lifelines.
3.1 BEFORE EACH USE inspect this equipment according to section 5.0. Do not use this equipment if inspection
reveals an unsafe or defective condition. Plan your use of the fall protection system prior to exposing workers to
dangerous situations. Consider all factors affecting your safety before using this system.
A. Read and understand all manufacturer's instructions for each component of the personal fall arrest system. All
DBI/SALA anchorage connectors, harnesses, and connecting subsystems are supplied with separate user
instructions. Keep all instructions for future reference.
B. Review sections 1.0 and 2.0 to ensure system limitations and other requirements have been followed. Review
applicable information regarding system clearance criteria. Ensure changes have not been made to the system
installation (i.e. length) or to the job site that could affect the required fall clearance. Do not use the system if
changes are required.
3.2 SYSTEM INSTALLATION: Figures 1 and 2 show typical Single Span and Multiple Span Vacuum Anchor horizontal
lifeline installations. The horizontal lifeline system should be positioned at a level that will minimize free fall while
allowing ease of use. The horizontal lifeline should be positioned near the work location to minimize swing fall
hazards. The connecting subsystem length should be kept as short as possible to reduce the potential free fall and
required clearance distance. Both Vacuum Anchors must be installed at approximately the same elevation so the
horizontal lifeline system is not sloped more than five degrees.
Step 1. Determine the locations of the Vacuum Anchors and evaluate the Anchorage Structure strength in
accordance with section 2.3. Determine the span length and evaluate the required clearance using Figures 6
and 7 along with Tables 1 and 2. For Multiple Span Systems, use the length of the longest subsystem to
evaluate fall clearance.
Step 2. Attaching Vacuum Anchors: Refer to the Vacuum Anchor instruction 5902157 for complete installation
information.
Step 3. Secure each end of the horizontal lifeline to the Vacuum Anchors with the snap hook or carabiner. Loosen
and reposition the rope tensioner as required.
Step 4. Remove the slack from the horizontal lifeline by pulling the rope through the tensioner by hand. To tension
the horizontal lifeline, using a pointed bar or a 1-1/8 inch wrench, turn tensioning nut clockwise until
tensioning is no longer possible. Do not modify the rope tensioner to achieve greater lifeline tension. See
Figure 8. The final tension will be 300 to 450 lbs. (1.3 - 2.0 kN).
