You mean this one?
Please see my revised below.
1) Access control, for exit, we use push button. Is it okay? Do we need to change to a card?
2) The sample control. We need to control all samples including PA, too?
3) For maintenance and housekeeping people, do we need to give them a visitor badge? Or, just sign in and it’s enough.
Aof, I want to ask you. In the whole procedures, just only 3 questions you want to ask? Please confirm my understanding.
