Subject: Questions About Perchloric Acid

I have one good question and two dumb ones. They are:

What is a good chemistry and design for a scrubber to be used to 
control emissions of perchloric acid from small scale heating 
operations done in common hoods?

Is there a quantity of perchloric acid that is so small that it can 
be handled without benefit of a special hood, even if heated (Is 
there a de minimis quantity)?

What is the derivation of the NFPA 45 requirement that HClO4 not be 
heated by flame or in an oil bath? I can guess, but I don't know.

Please advise. "Inquiring minds want to know."
