Temperature mapping technology has greatly contributed to the improvement of the cold chain process. Without it, temperature-sensitive items are compromised, which could mean loss of profit as well as liability.
Temperature Mapping Guidelines
The practice of temperature mapping involves the recording and monitoring of variations in temperature in a three-dimensional (3D) space. This is often used in warehouses serving as storage venues for such things as pharmaceuticals, perishable goods, certain types of evidence, etc. Even the smallest storage unit, a box if you will, can have varying temperatures within it. Case in point is your regular household refrigerator. The existence of temperature variation is why there are instructions to not place particular items in the fridge door.
It is recommended that temperature mapping and validation be conducted at least every 6 months as whether cold storage refers to a fridge, a freezer, a cool room, or an entire warehouse, you can expect variations in temperature up to as much as 10 degrees Celsius in the different parts of the space. These variations can be brought about by a whole list of variables. For instance, areas near cooling fans have a lower temperature than areas near a vent or a door. The middle of the room would also have a different ambient temperature than that in corners. Other incidentals could also cause changes in temperature, such as the volume of storage items in a unit. A full unit understandably would have a different temperature from an empty one. Another environmental variable? The presence of human beings. All these and more can lead to varying and fluctuating temperatures in one storage unit.
The mapping of temperature does not really aim to produce a uniform temperature throughout the room, although it can be used to tweak the cooling systems to lower or raise temperatures as appropriate. The whole point of mapping is to determine what temperature variations occur in a facility and use the information to plan out the specific placement of items as well as avoid incidents of them happening if they can be controlled. The important thing is to make sure that the items are not compromised and that the entire storage and transport process is not put at risk of non-compliance with pertinent regulations.
Temperature mapping indicates to those responsible which areas should not be used for storage and which activities should be avoided to prevent temperature fluctuation. Through it, companies can successfully adhere to good manufacturing process requirements for temperature-sensitive products.
Temperature Mapping is a continuous process involving regular checking, monitoring, and calibrating. The integrity of the cold chain is completely lost without it and CoolPac has developed temperature mapping guidelines to enable customers to conduct warehouse temperature mapping themselves. CoolPac then analysis the results and produces a temperature mapping report that can be used for cold chain compliance.
