A totally bad piece of advice. Fresh air is one thing, but oxygen is
quite
another. Firemen do not use oxygen bottles on their backs. Let that be a
reminder when reading Lew's posts.



huh? I've dressed out for a few fires - with O2 on my back.



I really doubt that. I'd sure like to know what kind of masks you're
using. If it is true then someone better call in a safety officer. Even
a tiny leak of pure oxygen in a fire can be deadly. Most masks, Scott,
MSA, etc. use compressed air in their bottles. Not Oxygen. (Twenty-eight
years of full time fire fighting experience talking here.)
