Myth #3: People stranded in sit harness all have similar problems to overcome.
Truth: Not so. Overweight climbers stranded in a harness may suffocate and die within minutes if not rescued. Sit harnesses squeeze gut mass into the abdominal breathing space and cause the user to suffer advanced suffocation symptoms in a matter of seconds. Stranded climbers need to be brought to firm ground or use an etrier or similar device (prusik loop) to relieve abdominal pressure.
