Untrained external personnel (such as external construction personnel or maintenance personnel) should be given special detailed guidance and supervision when they need to enter the clean area during production.

Personnel engaged in animal tissue processing or personnel engaged in microbial culture unrelated to current production are generally not allowed to enter the sterile drug production area, and when unavoidable, the relevant personnel purification operating procedures should be strictly implemented.

Employees engaged in the production of sterile products should always report any abnormal conditions that may lead to contamination, including the type and extent of contamination.
