Indeed, temperature mapping, also known as thermal mapping, is a critical Good Manufacturing Practice (GMP) utilized by businesses to systematically monitor and uphold specific environmental parameters. This essential procedure guarantees the consistent maintenance of temperature and humidity levels within a regulated area.
What is Temperature Mapping
It is the measurement and documentation of temperature distribution within a room by determining the hottest and coldest locations. The World Health Organisation (WHO) has identified “mapping” as a tool that may be used to locate problem locations that need to be treated, e.g. by changing the distribution of existing air to eliminate hot and cold spots. A temperature mapping study is conducted for a period of time that can range from a few days to a few weeks. It also monitors the room temperature in various locations.
Benefits of Temperature Mapping for your Facility
Know the locations of any hot and cold spots in your facility
Have documented records of the environmental conditions of your facility
Be able to determine the optimum storage locations for temperature-sensitive product/equipment
Make sure that all requirements for the storage of your raw materials, in- process materials, finished products, stability samples, and components are meeting good manufacturing practices requirements
How We Do
At Facility Services, we employ data loggers to measure temperature throughout the entire space, a standard practice for most users. Typically, six data loggers are strategically placed at the top and bottom of the area, each equipped with a sensor in the middle. In addition to space temperature, users may also opt to monitor the overall room temperature for comprehensive data collection.
What is the difference between Temperature Mapping and Temperature Monitoring?
Temperature mapping is done by deploying data loggers to various locations for minutes to map temperature and humidity distribution. Facilities can identify issues and implement adjustments based on this data. The door openings, electronics, and HVAC systems all cause inconsistent temperature readings.
Temperature monitoring is a common practice implemented following a temperature mapping study. Continuous monitoring is provided in this method with fewer data loggers. Temperature monitoring may also be required by regulating bodies
Where is temperature mapping performed?
Mapping temperatures that impact product quality is crucial, irrespective of location. However, relying solely on thermometer readings from one point on the equipment can be misleading. For instance, in a refrigerator, items at the back are often colder than those near the door. Uneven temperature variations pose a risk of rendering products unusable. Manufacturers must carefully weigh the costs and potential risks associated with this practice to ensure consistent product quality.
How frequent should Temperature Mapping be conducted?
Most users only perform mapping once a year. However, during the hotter or colder months throughout the year, there is a high demand for Temperature Mapping. Building or facility managers alike map the space to better understand how ambient temperatures influence the environment.
