Air ducts/electrical cable

is there any requirement that says air ducts can not lay on top of electrical cables, computer cables where they all cross ceiling joists? The air ducts are not being supported by the cables, just contacting.


"The air ducts are not being supported by the cables"

They aren't?

Ducts ARE being supported by whatever they are laying on.
