Leslie,

You need to check with the harness manufacturer as to its suitability.

Generally if the harness is used for fall arrest it should be capable of holding the fallen body in the upright position.

The most effective way to do this, is to attach the fall arrest device to an point on the centre of the chest or the middle of the back. This cannot be achieved by using only a sit harness.

Sit harnesses are usually only used for some work positioning, or work restraint tasks with full body harnesses being used for fall arrest.

Petzl do a work and rescue catalogue with a big table of harnesses, telling ya whats ok and whats not.
