Question:
Hi Charlie and Company,
You folks do a great job with this forum, thanks!
I'm working in an industrial facility and in one of the machine rooms there is an installation of 1-inch EMT containing both control conductors and small pneumatic copper lines for equipment. Is there any Code rule that prohibits installing equipment other than wires in electrical conduit?
Any help would be appreciated.

Answer:
Hi Russell, thanks for the question and your kind words.
Yes, there is an NECA rule prohibiting such installations. It took me a while to find this one as it is not referenced often. Section 300.8 indicates that raceways or cabletrays are not to contain any pipe, tube, or equal for steam, water, air, gas, drainage, or any service other than electrical.
Hope this is useful for your situation.
