Process Isolation procedure - Trial transhipment approval 1
Some operations require a trial transfer of equipment before completion or return to normal, in which case a trial transfer request must be made.
Trial transport requires removal or partial removal of the isolation implemented.
Trial transhipment will be approved by the licensor. The issuer will check and sign the permit and the quarantine certificate in the respective places.
After reviewing the isolation with the isolator, the licensor authorizes the isolator to remove the necessary isolation. The quarantine can only be removed after authorization and a quarantine certificate has been signed.
