For those interested in the strengths of the climbing equipment they're
using:

I recently received the results from some pull tests (Pulling on two ends of
a material until it fails) from Salt Lake County Sheriff's Search and
Rescue.
Tests include various pieces of webbing, rope, prusiks, various knots, as
well as a carabiner and a litter.
The tests are all based on static loads (constant strain), and does not
figure in the dynamic forces from drops, etc...

This isn't the final word in breaking strengths of materials, but it is a
nice heads up.

If you would like to see the results of these test, I'll be happy to forward
them to you.
