Re: Re: Using SF6 for cap../ safety note

Hi everyone,

The talk of the dangers of SF6 to the skin have me puzzled - isnt this the
gas that physics teachers breathe in to make their voices go very deep as the
speed of sound is slower in it (as opposed to helium which makes your voice
go high)? This would seem to indicate to me that it should be relatively safe
to use. I know that before breathing it in you should take a big breath of
air so that you dont faint from oxygen starvation.

Catch ya later,
