How dangerous are fungal floors on their own? I decided to do my first lab start recently, and things have been going pretty well. The only issue I really have is that the stairs to get up to level -1 are surrounded by rooms filled with fungal floors. I've searched the entire level that isn't contaminated, and there isn't a single set of stairs going up.  


At first I planned on just making some fire weapons to remove the floors, but it won't go through metal doors (I think) and it may destroy the stairs. So my plan at the moment is to try to find protective gear and just walk through. BUT, if I can walk over the fungal floors without issue, then I would be fine.
