APPLICATIONS
1.1
PURPOSE: DBI/SALA rescue and positioning devices are designed
to be components of a rescue-positioning system. This equipment is
used for applications where personnel need to be raised or lowered
over a vertical distance. The maximum working load for this
equipment is one person [350 lbs. (160 Kg.)] The system is available
with 3:1 or 4:1 lifting ratios. When using this equipment for personnel,
federal law (OSHA) requires that a secondary or back-up fall
protection system be used.
NOTE: The back-up or secondary fall protection system is not required in
applications where the RPD is only used to retrieve personnel (i.e.
emergency rescue operations).
A. POSITIONING APPLICATION: In this application, the RPD is
used as part of a complete positioning and personnel riding
system. Such systems typically include a full body harness,
boatswain's chair or work-seat, independent personal fall
protection system, and the RPD. See Figure 2.
