Semiconductor manufacturing involves the use of highly toxic chemicals, both in the manufacturing process itself and in ancillary uses, such as agents that help keep the clean rooms clean. I'm sure these converted clean rooms are excellent at negating microbial and particulate contamination, though I have to wonder how much concern has been given to negating chemical contamination, given the purpose these facilities previously served.
