Is dust a problem? It looks like everything is uncovered, even when moving big barrels of it around on a forklift. I would think that getting some dust in there would reduce the quality of the ink.
At a guess I'd say the whole place has really decent extractor fans as no one really seemed to be wearing much protective gear... and I assume there would be ample chemicals n the air. I'd also guess fans would do a lot for clearing dust as well as stray chemical fumes.
