Can a pass-through be from the HD negative pressure room directly into non-classified air (general pharmacy area) or does it have to be into the ante room?
I'm reading USP 800 and it says "pass-through chamber between the negative pressure buffer area and adjacent space). We are designing a new facility and are reviewing plans proposed by a company.

Good question! I would first make sure that your state board of pharmacy doesn't have limitations associated with pass-throughs. Any pass-through needs to be a well-constructed stainless steel box with interlocking doors. It cannot be a sliding window. Ideally, it should be a HEPA filtered purged pass-through when used between the negative-pressure HD buffer room and the general pharmacy. Pass-through refrigerators between a negative-pressure buffer room and any space are prohibited. Hope this helps.
