Pharmaceuticals/airlocks desing


QUESTION: Dear Michael:
Can you help me with the desing of the airlocks for personal entrence to hormonal manufacturing áreas of solid products.
Thank you very much.

ANSWER: Dear Ronald:

To answer your question properly, I need to know whether:

a. the hormone production section is part of a facility that also manufactures other non-hormone products, or not;

b. whether the airlock divides the hormone area from the non-hormone area; or it is within the hormone area.

a.The hormone production is a new facility. Distance 70 meters from the non-hormone products. This new facility is for oral solid products and injectable.

The WHO has published an excellent guideline titled:

Technical Report Series, No. 961, 2011 - Annex 5 - Supplementary guidelines on Good Manufacturing Practices for Heating, Ventilation and Air-Conditioning systems for non-sterile pharmaceutical dosage forms. You can download this document from the WHO website.

Section 4.7.11, discusses airlock design. A "bubble airlock" will meet your needs.

If you cannot find this guideline on the WHO website, please contact me at and I will send it to you
