What is Temperature Mapping?
Temperature Mapping is an auditing process for assessing temperature variations in a warehouse or storage facility along a three dimensional plain to ensure temperature control in the cold chain. The process may also be referred to as thermal mapping. It is mostly concerned with identifying hot spots and cold spots in a space that’s is supposed to have uniform temperature throughout. Unfortunately, temperature does vary within a space especially in areas near doors, windows, vents, fans, and can also be due to personnel traffic. Cold Chain Validation on the other hand follows the journey of shipped items through the cold chain and pinpoints spots that call for temperature monitoring.
Why is it important to carry out Temperature Mapping?
With temperature-sensitive perishable products, even a small dip or rise in temperature can affect their shelf life and their value. Raspberries and stone fruits, lettuce and flowers must not be stored too cold whereas vaccines and temperature sensitive medicines decrease in effectiveness if they are stored in temperatures that are too hot. It’s common for temperature-controlled warehouses to suffer fluctuations within the temperature range, temperature mapping is absolutely necessary to protect the quality of the product as well as to comply with official standards on how items like perishable food, chemical products, and drugs are to be produced, shipped, and stored.
The distribution process is particularly pocked with potential temperature shifts in the cold chain. To avoid compromising the efficacy and value of a temperature-sensitive product, it’s essential that mapping would have been done. Through it, suppliers can ensure compliance with industry-specific regulations, locate problem areas in a storeroom, identify and remedy problem areas to optimise efficiency and cost-effectiveness of a cold chain operation, as well as preserve the quality of the products being manufactured and distributed.
Temperature mapping validation is often implemented in places such as warehousing facilities, cool rooms, refrigeration units, freezer rooms, cold storage, logistics warehousing, transport vehicles, airline containers, and shipping containers. Once a facility is properly mapped, it is then time to lay out a detailed plan to install temperature monitoring devices in various stable and unstable areas. With these in place, managers and technicians are able to keep constant watch on spots of possible fluctuation. A wireless temperature monitoring system is often installed to easily see temperature excursions and be alerted to temperature problems as they occur.
Through this process, the cold chain is able to improve overall efficiency, allowing different parts of the world access to various important temperature sensitive items. Pharmaceuticals and biochemical products such as drugs and vaccines can travel across the globe without losing efficacy. Cold chain validation enables suppliers and distributors to ensure temperature stability from the beginnings of production to the last stops in distribution and any other step in between.
