I was thinking about the relationship of a shared ante-room between your HD and non-HD clean rooms. Would it be better to have sub-ante designated between both areas. I was thinking of this type of design:
Ante Room – ISO 8 – Positive Pressure (+) - this area would have a sink for hand washing and the pharmacy personnel would adorn clean room attire. This area would have a line of demarcation (dirty vs clean). Note if planning to go into the HD room, a second pair of booties would be worn.
Then the staff would go into one of two sub-ante rooms. This would be an area of greater pressure than the Ante Room and have an ISO 7 classification. One the HD side, the employee would adorn a chemo gown and respiratory equipment would be kept in this area. A line of demarcation would be present to designate contaminated vs non-contaminated. Clean supplies for the rooms, sterile gloves, hand ETOH, etc. would be kept in both sub-ante.
My concern having just one ante-room is the environment might contaminate the HD clean room. As we all know, the sink can be a great source of growth. If I have this area positive pressure to my HD room, I am concern of contamination risk. Am I over thinking the design of this environment?

You can have two anterooms and that would be an ideal situation. You can also manage the spread of contamination through robust work practices by using a doffing line inside the negative-pressure buffer room. I am attaching a couple of articles that was just written discussing this work practice.
