Regardless of where these transformers are situated, I reckon there should be shrouds over them, from a Health and Safety perspective.
I have never seen such a shroud on an installation like this.
The generally policy is that only authorized, safety trained personal are allowed in the room.
Usually there is no need to go in the anyway as all that will be in there are the transformers and some lights.
I built one of these rooms as a subcontractor to the power company.
Once it was powered up it was off limits to me.
