Do a little Google search about welding and brake cleaner. The intense IV days from the arc reacts with the cleaner producing phosgene gas. Think gas attacks WWI.
The bit I've read of it, those that didn't die wish thy had !! Very dibilitating. This is no joke people !!! Can even happen at a fair distance.
Ya, I use the crap out of brake cleaner !! Get something from a welding shop.
