BC terminology question

[southsoundtree]

A barber chair BC is frequently thought of as the top (above the cut) splitting.

What is the proper name of the spar splitting from similar internal force overload? The situation where a climber using a flipline from D to Dring will be crushed?

I was training my employee the other day, and he asked if it is also a BC. I had to tell him that I didn't know if there was a proper/ commonly used term to describe this situation.

I've always referred to it as a BC and have always heard it referred to as a BC, so if I'm wrong I'd like to know too.

Spar split sounds like a good one to differentiate from the top splitting and extending behind the stump like the real barber chair put into the shaving position.

Anyone have anything on this?

I was told that it would be called a reverse BC. A regular BC being the top section splitting upwards and a reverse BC would be the spar below a climber splitting downwards.

is it still a BC if the top section comes all the way off, then the butt comes back and up without splitting? (like if you were felling a tree from the ground)
