What is it: Temperature mapping measures and documents how temperature is distributed throughout equipment or a facility. The purpose is to determine which areas suit sensitive goods, which are at risk, and what needs ongoing monitoring.
**How: **The process is the protocol, the execution, and the report, plus implementing whatever the findings require.
Why: An efficient process cuts resource use, focuses effort where the value is, and gives assurance of ongoing compliance. A neglected one risks recalls, citations and warning letters.
Where: Every temperature-controlled environment in GxP, from incubators and fridges to walk-in rooms and large-scale warehouses.
How often: Prior to use, and again whenever a major change occurs or seasonality demands it.
