My corner of the office is being used as a storage unit for old files?

I work in an office that has way too many files. I sit in the back of the office and since space is a precious commodity, the management has started stacking boxes of files about five feet away behind me. The boxes are cardboard and not stable. Two days ago they fell and I got up just in time to avoid getting hit. They stacked the boxes in a way that they are more stable now but I'm still nervous about them falling on me. I've spoken to the management about this but they say the boxes are stacked in a more stable way now and it won't happen again. Is there a government agency or something that can make them put those boxes away from me? I'm in California by the way.
