I'm still working on the lab coat issue!

I'm reviewing the NIOSH doc 2012-147 for Nano S&H ( and it has 2 specific references to lab coats (1st time I've seen anything so specfic!):

Impervious laboratory coats (noncotton). (If nondisposable laboratory coats are used, they should remain in the laboratory/change-out area to prevent nanoparticles from being transported into common areas).

At a minimum, for all laboratory activities, wear impervious (non-woven) laboratory coats (or coveralls, or a work uniform that covers the arms); long pants without cuffs: a long-sleeved shirt; closed-toe shoes made of a low-permeability material, or disposable foot covers; eye protection; and appropriate chemical-resistant gloves (depending on the chemical exposure).

My questions:
1. Does this only refer to work with nanomaterial powder? vs liquid/solvent solution?
2. What material is "non-woven"? Aren't the polyblends are woven to some degree?
3. If the lab coat is supposed to be "non-woven", why not the coveralls or work uniform?
4. What S&H benefit does "non-woven" provide?
5. "Impervious" to what?
6. Can "disposable" lab coats be taken out of the lab area? How come only "nondisposable" coats must remain in the lab?

Thanks for your insights!
