Gary,

It would trigger both a PRCS permit and a Hot work permit at our plant. Gas,
arc, tig, brazing, soldering...wouldn't make any difference. I'd advise
against using acetylene in an unventilated CS owing to the broad explosive
concentration range.

Quick confined space question.  In your organization, does welding in a
confined space result in classifying that space as a Permit Required or
Non-Permit required CS?  We presently classify the space as PRCS if welding
is being done.

Thanks,
