2015. If that is about the same incident it's quite a while before the current event (unless it's a typo in the article).
Sounds like they were likely running a laser cutter and the "generator" sound was actually an air compressor. (These are used to blow the smoke out of the way of the beam so that you get a cleaner, more accurate cut.)
Chlorine gas is a major risk with a lot of materials, but presumably there could by other kinds of nasty fumes depending on what they were cutting.
edit: others are saying that it was in fact CO, so I'll go with that. I'd still like to know what they were cutting, though.
