Maybe explain what it is you are calling an "emergency electric closet" and we may be able to better answer the question.

If what you have is a room that only contains emergency equipment items it may be good design practice to keep normal power items out of that space but isn't necessarily a NEC violation either.

Not in the same raceway though.
 
The OP is in MA, in MA the rules require two hour fire seperation of emergency transfer and distribution equipment.

I don't have the MA amendments handy so I can't post them or even look at them right now.

I pretty sure the answer to the OPs question is no, you can't run normal power inside the emergency elecrical space.
 
Yes I agree it's not the best practice and I know you can't run in the same pipe or j-box however As is the case most of the time I have little to no room I my electric room and the emergency closet containing a high and low voltage emergency panels is a room inside the normal electric room so running normal power conduits through the room may be my only option. I could not find a code violation and just wanted to know if anyone has done this before. Thanks

From a fire protection standpoint, I'm thinking maybe you can put two hour fire resistance between the two. Effectively you'd be making a chase through the area which contains the emergency equipment.
Do you have a fire protection engineer on the project?
