You will be fine and after the intros are over and you actually get into the lab your anxiety level will come down, I guarantee it. A wise friend of mine once said that when an inspector asked her a question and it either appeared that she was going to be cited or that she didn't know the answer she asked the inspector, "how do you do this in your lab" knowing that she was probably doing it fine in hers but was sort of trying to find out where the inspector was going with the question. And another wise friend of mine said, "answer the question (and shut up!)" Don't overthink it, just answer the question the best you can. I agree with the others, organization is the best advice. If you look prepared they will know that you are. If your policies and procedures are neat, look nice, etc that will also go a long way on the first impression. If you do get a deficiency you can always contest it if you feel that it is not appropriate. I've participated in inspections on both the receiving and performing side and in the true spirit of the inspection process, try and learn as much as you can on inspection day. Good luck, go get 'em and keep us posted.
