I work in steel fabrication / construction, the idea of 'engines off inside' hasn't caught on in Tasmania in the industry. When I was in Adelaide circa ten to fifteen years ago I recall the local food and beverage manufacturers all had signs to the effect 'strictly engines off inside'. Nothing worse than a workshop full of diesel soot, though the exhaust urea fluid (AdBlue) in the newer trucks does give it a distinctively more breathable aroma, so there's that. Very annoying.
