See Generator Plant floor plan drawing 11.2 A101 at bottom and top left, spaces labeled "UT."
Urea is used in fuel cells. Are there other uses of urea in generator or data processing equipment?
It could also be a snide comment about being in Utah, or an alternative to a sign saying "These aren't the droids you're looking for" or "Beware of the leopard". Back in ~1990 when we bid on rewiring the Pentagon, there were a lot of "we can't tell you what's here" or "too secret to let you run wires through it" spaces, along with a bunch of areas that almost certainly had too much asbestos to actually run wires through the plenum. (Our prime contractor didn't win the bid, which was probably just as well for them.)
