VENTILATION SYSTEMS IN PHARMACY INDUSTRY
(OP)
Hello Fellows!
Suppose you have a not so big pharmacy laboratory of a middle technology level.
On account of a manipulation of several quimical substancies in close rooms, which must be ventilated at the regulamentaries air rates.
Do you know which usual norms/rules are applied? What are the air rates to follow?
Thanks in advance.

RE: VENTILATION SYSTEMS IN PHARMACY INDUSTRY
ASHRAE has quite a bit of literature on the design of clean rooms.
On the other hand, if the Pharmacy is only a room with a bunch of drugs in it it can be treated as a normal room and only the equipment load in the room would have to be accounted for.
Not sure if I've helped or made things more confusing.
RE: VENTILATION SYSTEMS IN PHARMACY INDUSTRY
Not at all!
You just confirm my thoughts at this phase.
I will have to go deeper in the normative field. I'm just waiting for the up-to-dated chemo drugs list, the related process, to decide the ventilation method, diffusion and fresh air rates concerning.
Your help has been great! Thanks!

If they are not sure, they should seek for consultancy, not you.
Why is that? If you show yourself client-sensitive and study specific ASHRAE literature, decide to design "white" or "grey" room, six month later somebody from that company can appear, state that such cost was not necessary and blame you for that unnecessary cost.
Go to QA and push them until they give you their requirements in written!
RE: VENTILATION SYSTEMS IN PHARMACY INDUSTRY
You just pointed out the main aspect,i have to deal with.
I must say that I got already some data you mentioned (in written), an I have to consider those, as enough inputs like the chemo drug list, the layout, to do my study.
The task now, is to get some "grey rooms", I mean to manage some solution, which has to fulfill the actual normative stuff concerning the the legal requirements (you should be aware of it) for the interior QA and exterior QA, as well. My initial question is stand by.
Thank you.

Suppose you do nothing in this case, or just the minimal. They will blame you as well. The question is to get here a balanced solution, consider the normative requirements.
The 2nd aspect is to consider the design process in two phases, related to the outside QA, (that implies some significant investment) by monitorizationig in order to know what solution to treat the exaust air.

Is it an API plant or formulation plant? If formulation, what dosage form? Are you dealing with any exotic substances?
Have you been to USFDA and EU GMP websites?

But such situation, if I guessed well, make your task too hard, say impossible.
Big company would give you their developed specs and you'd be able to design according to that. Small company probable doesn't have it and expect you to develop all.
But that's not job for one small project! I was dealing with company specialized in specifications according to USFDA, but even they were not willing to develop some custom specs for one plant, they offered FDA approach or nothing.
You should do something similar: offer client to choose some level of FDA specs, or if he wants to keep it simple, you should find out production rate of diffrent toxical substances, install local exhausts (they are typical for labs), negotiate with client about air exchanges, filter class, type of flow... at the same time looking at standard ASHRAE reqirements.
I see no other approach.
RE: VENTILATION SYSTEMS IN PHARMACY INDUSTRY
Drazen, I must say that you got your shoes on the real world. That's right, it's a small company. The approach has to be carefully balanced for a system, which has to fulfill the Interior Air Quality IAQ requirements in the first project phase and leave the conditions, ex.: for doing the monitorization and the characterization of those exaust air emissions. In the second project phase, to design the solution to deal in accordance with the air-legislation.
Hello again Quark! Doesn't mean that are no rigth, but the investment is been enormous for the process equipment, and you know the limitations at this stage.... The client ask me to get an optimal solution.
Thank you, both!
