A.2.3. FACILITIES, EQUIPMEN T AND MATERIALS FOR STORING
1. The devices intended for storage should be located preferably in a separate area to which access is controlled and restricted to authorized persons.
2. A temperature monitoring system should be utilized to document temperatures and to alert staff when temperatures have strayed outside acceptable limits. Procedures should be in place for reviewing temperatures. If storage utilizes liquid nitrogen, either liquid nitrogen levels or temperature should be monitored and documented at an interval specified in the SOP.
