Behind the scenes access to critical shipments

What do haute couture clothes have in common with medical equipment and aircraft technology? Any guesses?On the face of it very little. However, at a closer look you’ll see that all of the above objects are critical.By critical shipments I mean high value, extremely time or temperature sensitive, or even irreplaceable objects – making it imperative that their location and temperature is known at all times.

Dry Ice Shipments in Air Transport

Adding dry ice in perishable shipments has been used as a cost effective solution to maintain cold temperatures for a limited time. Dry ice is solidified carbon dioxide (CO2) at very low temperature. Phase change diagrams establish the relationship between temperature, pressure and states of matter for carbon dioxide. Dry ice undergoes a phase change from solid to gas at -78oC under atmospheric pressure, without passing through the liquid state in a process called sublimation. Dry ice can be found in various particle sizes and shapes such as blocks, pellets or snow.

FedEx Express Establishes Default Temperature Settings on the B777F

Most pharmaceuticals need to be stored and transported in one of two temperature ranges: Controlled Room Temperature (15-25°C) or Cold / Refrigerated (2-8°C). Typically the sophistication of the molecules used in the drug and/or stability of it drives the need for tighter temperature control (i.e., more refrigeration).

Cold Chain for Beginners

Cold Chain is a term used to characterize temperature-controlled storage, distribution and transportation. The term can be misleading since it does not refer to “cold” temperatures in particular. Products that are sensitive to temperature variations, whether they be perishables such as fruits and vegetables or more sophisticated drugs and medical devices, are included in the term “cold chain”. However, cold chain is often more narrowly used in reference to temperature and time-sensitive high value healthcare products.
