My Reading on ASQ CQA HB Part I-IA~IE-s

Part IE1
IE1-Gossip
One way to work through the lack of a security clearance is to be
constantly escorted, with classified areas, equipment, and activities
shielded from view. This way, the auditor can evaluate part of the
process and interview the people on the line.
Some products may
be adversely impacted by the presence of auditors
or by the auditor’s health. For example, some pharmaceutical
products may be sensitive to people with certain medical conditions.
Medical tests may need to be performed and results evaluated
before the auditor is permitted to enter the processing facility. Wearing
appropriate personal protective equipment such as gowning to
limit human exposure may be sufficient to protect the product from
humans.
