An air cargo process expert for a leading Switzerland based airline, is responsible for defining the internal processes handling a wide range of temperature-controlled goods for customers. He needed to find a solution to repeated issues of Dry ICE cold contamination to other shipments, during storage and transport in the cool chain. Dry ice is often used to keep food products, medicine, or biological materials in a frozen or chilled condition. The objective of this exercise was to establish standards to store ICE shipments away from other shipments. Dry ice is a hazardous material under Code of Federal Regulations (CFR). Live drug products are stored in a warehouse and monitored to ensure they are within correct temperature ranges to maintain effectiveness and integrity in the cool chain and product quality preservation.

The specialist used several LogTag TRIX-8 loggers to monitor and carry out tests to determine how the Dry ICE shipments were influencing other shipments that were stored too close together in the warehouse and on the aircraft. The TRIX-8 loggers were used to measure the temperature influence with different packing options. The results allowed him to define process solutions to minimize the risk of future cold contamination in both the warehouse and in the air transport. Data was downloaded using the companion LogTag interface cradle and the easy-to-use LogTag Analyzer software.

Due to this satisfactory outcome from the tests, new processes were developed to maintain the continuity of
high-quality standards and to meet airfreight customers’ requirements in cold-chain logistics.
