Temperature Mapping – Warehouse

Variances in temperature are considerable, over the height and width of a racked warehouse or storage area, therefore many businesses have legislative requirements to complete temperature mapping.

Does temperature mapping only benefit the pharmaceutical sector?

MHRA licencee businesses have a duty to map as part of the licence approval, but mapping is more than a box ticking exercise. The MHRA Inspectorate blog has some great articles on mapping.

Door openings, windows, heating/cooling systems, rack positioning and stock on shelves has a massive impact on air movement and temperature.

Goods stored at height on racking, within ambient warehouses, will get a lot warmer in summer and cooler in winter, than those stored at ground level. However, the airflow around temperature controlled storage areas can also see similar effects occurring.

Mapping gives a view of these temperature variances and puts numbers behind the differences recorded. This allows informed decisions to be made so goods can be stored to meet their temperature requirements.

It’s beneficial for any business, that stores temperature sensitive goods, to consider mapping. Doing so gives temperature variance knowledge and assists with the correct placement of permanent monitoring sensors.

How should mapping be completed?

There are no defined standards for temperature mapping per se.

At Tek Troniks we follow the principles of the World Health Organisation standard. Our mapping processes are designed around the WHO standard and are UKAS 17025:2017 audited & accredited.

What we do:

  • Agree the mapping scope – An onsite meeting to review the area to be mapped, documenting the key elements including a plan highlighting the mapping points which must receive customer sign-off.
  • Installation & removal of the mapping sensors – Fully trained engineers come to site and install the sensors, as per the agreed plan. After ensuring data is being collected the sensors remain in place for an agreed period of time. After this time, the engineers return to site to remove the system.
  • Collation of data – Data is collated from the mapping system, typically 2,000,000+ data points based on a standard 7 day mapping cycle. A fully documented report is completed with the data synopsis in tabular and graphical format. The report includes a mapping calibration certificate for the work undertaken.
  • Presentation of the mapping report and report sign-off – An onsite meeting to review the report findings and assist with any questions following the mapping process.

A sample mapping report is available from our calibration team, contact us for a copy.

Our mapping specialist team are happy to offer advice, send quotes and make sites visits to discuss you mapping needs, get in touch with us today for more help.
