fall arrest harness has the fall arrest D-ring between your shoulder blades

Well now I stand corrected. I believe the only true "fall arrest
harnesses" are the full upper body type that you mentioned. The fellow I had
talked to at PMI told me the same thing. I believe some folks (myself
included)are using these work positioning, sit type harnesses with a double
lanyard + energy absorber (like the Zyper)attached to the front ring for
fall arrest. The issue of body position with this arrangement, as you're
caught from a fall, is a major concern. The fall is supposed to be cushioned
and limited in distance by the Zyper (6 ft to energy absorbed impact if you
fell from 3 ft above your lower attachment point) but still the body
position isn't good and I'm sure it wouldn't take much of a jolt to suffer
spine damage. Anyway - "up the tower" is no place to find out things the
hard way. I for one will certainly re-evaluate and more than likely I'll go
to a "true" fall arrest harness.
