We had that the oil refinery:  All important electrical installations
were pressurized with dry nitrogen, mostly I think to prevent the
airborne hydrocarbons from liquifying the plastic.

The shop-joke was to manually tweak the central pressure regulator
when somebody headed out to do maintenance, and see them get hit by
a cabinet door swung outward by half an atmosphare over pressure :-)
