Yep. I worked a cnc table cutting fiberglass fabric for sailboat manufacturing. I was told the mask or ventilator thing (had filters and they tested it with smelling salts - I don't recall well) was only required when it was cold, because that apparently made the fiberglass worse for you. And that requirement was really just a suggestion.
This was also Florida, US. So... You know.
In this context production means servers or machines which make money in a business. The partner term is normally staging: a testbed environment.
