Pumping at work

Before I start this, I am very grateful for a job where I am still able to pump whenever I need to. But they recently moved a few things into the room that bother me and it's probably just me but thought I should ask. I work in a lab and so we have a lot of medical stuff come through here. It's a lot of storage mainly of different things. The room I pump is was an old office. Nothing but a desk and chair in there. Until yesterday when they moved really old x rays of autopsies in there. One of my coworkers said I should check into it saying it might be unsanitary. Any input would be greatly appreciated. Thank you!
