You will not be feeling very good after a fall either. You will experience
a nasty shock when the arrest lines reach their full stretch. You could
easily hit your head in the fall etc. You will probably be in better shape
than if you hit the ground though. Chances are pretty good the shock will
put you out but I could be wrong. I have never talked to anyone that has
ever had the opportunity to test their rigging.
I am a Volunteer FF while in Montana. A tower rescue has never been
trained. We have a search and rescue team but I am sure I would be the one
with the most tower climbing experience in the area. The response time
would not be great as the towers are not close to the stations. Our Ladder
truck can reach 55 ft. I hope we never get that call. I am not an EMT so I
do not know what the dangers are from passing out do to leg constriction.
It can't be good but I don't know how life threatening it is.
We risk our lives everyday. You can do everything right and it still might
be your time.
