FP Fall Arrest
Solid stainless steel rings serve as attachment points for fall arrest lanyards.
Positioning: D-rings on each side of the hip belt allow for safe positioning on
an exposed work site.
Rappelling: Prolonged operations on a rope can be conducted in comfort, as
the hip harness with both leg loops turns into a comfortable seat. By virtue of
its slide-through design, normal walking is unobstructed.
Rescue: The back D-ring can be used for safe rescue from confined space.
alphaFP pro additionally features hose protection tunnels on shoulder pads
and quick connect buckles between harness and SCBA for ease of mounting
or emergency removal during operation.
Belt
The comfortable alphaBELT Pro is the optimal configuration. Compared to the
alphaBELT Basic it includes:
Versatile alphaBELT Lanyard
Safe rescue seat function
Quick connect buckles for SCBA (separating function)
Elastic fixation for overhanging strap ends
To build the rescue seat (EN 1498, class B), an additional rappelling carabiner
(according to EN 362) is required in the front loop of the belt. For this purpose
MSA recommends the MSA steel Tri-Lock carabiner, tested and approved for
use with an SCBA. It is an optional accessory and not included.
