Yes, there are, but those are enclosed with PVC, not drywall and paint or other standard wall materials. Flammability and moisture concerns would be at the top of my list. I don't know enough to say if it should be a concern or not, just that I would want to be able to arrange my rack/shelves/etc. so they aren't touching the walls of my house.
