When the inspector shows up, require proper identification and presentation of proper credentials (you may want to compare them to photographic identification
such as driver’s license). Decide whether or not to allow access (remember – there are very few valid reasons for turning away inspector). And, remember, denial of access may create the wrong impression that something is wrong at the plant. If it is a criminal investigator with a proper warrant, a denial of access will subject you to arrest for contempt of court.
If a warrant is presented, get a copy of it. Read it. Ascertain the scope of the warrant as the investigator is tied to the warrant. The warrant will also determine what records can be seized.
After presentation of credentials make the inspector give you a statement regarding what he wants to accomplish; with whom he wishes to talk with; and what he wants to obtain in regard to records and documents. An agreement should be reached covering: witness interview schedules (if appropriate); documents to be produced; sampling protocols; and confidentiality issues. The agreement should then be reduced to writing and provided to the inspector.
