It involves the segments involved in the manufacture, storage and transportation of temperature-sensitive products.

What is Temperature Mapping Study, Validation & Qualification?temperature-mapping-of-warehouse

Temperature mapping study analyzes the distribution of temperature and humidity. This test is across the temperature-controlled area under various practical conditions. We carry out these tests to check the uniformity of the temperature within the area. This is applicable for cold rooms, warehouse, refrigerator and vans for transportation. These are for transportation and storage of medicines, vaccines and foods. Please see our video for a detailed understanding.

Assets which need Temperature mapping study, qualification & validation

We cover all the following categories of facilities. These are for storage and transportation of medicines, vaccines, food etc.:

  1. Walk-in chillers and freezers for storage purposes.
  2. Cold rooms for storage of medicines, typically between 2 to 8°C for medicines.

Procedure for Temperature Mapping Study & Temperature Qualification

We study the whole system under various conditions:

  1. Empty condition without any loads inside the storage area.
  2. The fully loaded condition with 100% loads within the storage area.
  3. 60 to 70% loaded condition, in which the area will have loads up to 60 to 70% of the storage area.temperature-mapping-of-medicine-cold-room
  4. Power failure condition to study the duration for which the room will remain
    within limits after a power failure without opening the door.
  5. We test the door opening conditions. This will establish the duration for door opening without affecting the interiors. We independently test all doors.
  6. We carry out the startup verification process. This is to find out the duration required to achieve the desired cooling upon startup.

Protocol for Temperature Mapping Study, Temperature Qualification & Validation
We carry out the process of temperature mapping study as per the protocol. We issue this before the test for approval by the client. The protocol indicates various details of the assets and methods of various tests. In the protocol, we also consider the usual operating practices of the customer. We incorporate these aspects while carrying out the tests.

temperature-mapping-of-medicine-van

Suppose the customer always operates the vehicle at around 50 % load, In such a case, it is ideal that we carry out the test at 50% loaded condition also. Suppose we qualify a vehicle for 2 to 8 Degree Centigrade. This means that the entire storage area of the vehicle will remain within 2 and 8 Degree Celsius. This is subject to the current set of cooling unit, evaporator, sensor, controller etc.
Consider that we qualify a box for 2 to 8 Degree Centigrade. This means that the box will remain within 2 and 8 Degree for a certain duration. So the customer should not keep the medicine for a longer duration. Also, we identify critical conditions such as the duration for which you can keep the door open. If there are any suggestions and corrective actions, we state the same in the final report. This process will qualify your Warehouse, Cold Room, Chiller, Vehicle or Boxes. This means that they are suitable for storage and transportation of Food & Medicine.

Temperature mapping study using Bluetooth & WiFi data loggers

temperature-mapping-study-of-van

In the conventional method of temperature mapping, we use normal data loggers to record the data. After the tests, we remove all data loggers and download the data. The disadvantage is that if there are excursions, we will not notice until we download the data. In the case of corrective actions, the customer has to undertake the corrective actions and carry out the complete test once again. This will result in huge expenditure on cost and time.

In order to overcome this problem, we can use wireless data loggers. We will be using wireless monitoring systems instead of data loggers. There are different types of wireless data loggers. We use Bluetooth data loggers for the same purpose. The data transmission is in real-time through a local server or a cloud-based server. We can monitor the data in real-time.

In the case of excursions of temperature or humidity, it can generate alerts. Upon receiving alerts, the customer can look for problems and can take corrective actions. We can start retesting upon completion of the corrective actions. The data loggers can remain in the same locations while undertaking corrective actions. Thus a huge amount of money and time can be saved in the process.

Software validation for temperature monitoring systems

We offer validation of software of temperature  & humidity monitoring systems. For many clients, there is a requirement to validate the software. We can do this after installation by the pharma distributor in their warehouse or cold room. We carry out such validation on software by different manufacturers. Also, we offer validation of software for the temperature tracking system for vehicles. Please see more on our services for software validation.

Temperature Qualification

difference-between-mapping-study-and-qualification

Temperature qualification qualifying and certification of assets in Cold Chain applications. This ensures that the asset is capable of maintaining the critical parameters. This is for the entire area under normal operating conditions. Such a process will provide an insight into the performance aspects of the equipment or the area.
 
Temperature is a major parameter for qualifying equipment. But, this need not be the only parameter or the main parameter. This depends on the application and type of equipment. In the article, we explain about Temperature Qualification.

What is the Difference between the Mapping study and Qualification?

This is often a subject of confusion which we will like to clarify. In brief terms, qualification is a much more elaborate process than a mapping study. A mapping study only analyzes the distribution of temperature and humidity (if applicable). The result will show whether the distribution is uniform.

Mapping study is only one part of the qualification process. The qualification procedure has a lot of other verification and tests. These are to check whether the installation and operation of all the major equipment are as per specifications. Also, it will check whether they are capable of achieving and maintaining the temperature and humidity.

Suppose we qualify a cold room for 2-8 Deg Centigrade. This will mean that the entire cold room is capable of maintaining the temperature of 2-8°Celsius. All international pharmaceutical companies prefer their distributors to do qualification for critical assets. Such assets include cold rooms, vans, boxes etc.

Temperature Qualification (and humidity if required) is a bit elaborate process than a mapping study. This involves mapping study as one part of the process. These series of tests are for any temperature and humidity sensitive areas. Temperature Qualification involves complete identification of entire equipment inside the enclosed area. These include chillers, sensors, evaporators, cooling units and dehumidifiers.

We carry out the study of the complete system under various conditions. In a qualification process, we check all major equipment including the cooling units. This includes checking of various parameters and records of this equipment. In a mapping study, we will be checking only the temperature distribution inside the area.

  8. Thermal Insulated Containers which keep medicine with or without auxiliary power.
  9. Stability chambers which have controlled temperature and humidity environment.
  10. Humidity Chamber having a controlled humidity environment.
  11. Incubators (Temperature & Humidity).
  12. Clean rooms having controlled temperature, humidity and particle count.
  13. Trailer and Trucks, Reefer trucks and refrigerated vehicles. These are for consumer goods, perishable items, FMCG, frozen food, fruits and vegetables.
  14. Cool cells, Thermal pallets, thermal pallet covers etc. for Airports to handle medicines and vaccines for CEIV and IATA certification.
Temperature Qualification Process

The process involves a variety of tests as per our protocol specific to each equipment and client. Irrespective of model and type of the tested piece, we prepare the protocol for each device and we test each of them separately. You can see a sample protocol for the qualification process. The process involves the following procedures:

  1. Design Qualification (DQ)
    temperature-qualification-of-reefer-truck-van

    Temperature Qualification of a Reefer

    The design of the equipment should be adequate to achieve the desired results. The results are not to be defined by the installed equipment. eg. A cold room should maintain a temperature of 2 to 8 Deg Celcius for keeping medicines. Here the desired result is that the temperature should always be within these limits. Hence all the installed equipment should be suitably designed to ensure the same.

  2. Installation Qualification (IQ)

    This process involves various checking to test

    1. Verify that the calibration documents are valid for Various components.
    2. Ensure that the client maintains all equipment as per the recommendations of the manufacturer.
    3. Check the procedure to ensure that the client operates the equipment as per the recommended operational procedures of the manufacturer.
  3. Operational Qualification (OQ)
    temperature-qualification-of-refrigerator

    Temperature Qualification of Refrigerator

    This procedure involves checking all aspects affecting the operations of the equipment. In this, we check various controlling instruments of the asset. This is to ensure that it is possible to control the asset properly. eg. a Thermostat of a freezer is a controlling instrument. If it is not working properly, it will affect the operation of the asset.

    Temperature mapping study also is generally a part of the procedure.

  4. Performance Qualification (PQ)

    The performance of the equipment varies as per the distribution and the type of material kept inside the area. Hence it is important to test the equipment under all such circumstances. The whole process will involve rigorous testing for extreme conditions to ensure the reliability of the same.

A typical protocol for Temperature Qualification

An example of a typical protocol  procedure is enclosed at this link: Download typical Protocol

temperature-qualification-of-cold-room

Temperature & Humidity Qualification of a cold room

You may contact us for any specific protocol requirements of different authorities. Examples are SFDA temperature mapping protocol, NHS cold shipment validation protocol etc.

The temperature qualification process of the asset is complete if all the above tests and verification are successful. In such a case, we certify that the asset is suitable for the application. It is possible that a certain deviation or non-conformances happens during the processes. The client has to rectify this and we will carry out a retest. Upon completion of the retest, the process is complete.

Temperature Qualification using Wireless real-time data loggers

Normally we have been using normal data loggers for a qualification process. After conducting all the tests, we remove the data loggers and download the data. Upon analysing the data in our software, we find out whether all the tests were satisfactory. As you are aware there are a lot of tests in a qualification process. It involves the loading of goods by the client as well. If the results are not satisfactory after all these efforts, it will result in a huge loss of time and efforts.

In order to overcome this problem, we can use wireless data loggers for data collection. For small to medium cold rooms, we can use Bluetooth data loggers. These are real-time data loggers which transmit the data continuously to a cloud-based server. We can set alerts for temperature or humidity excursions. Thus we can take corrective actions if we find out any deviations during the test process. If corrective actions do not take a long time, the customer can carry out at the same time. Thereafter we can start the test process once again. This will save a lot of time and efforts.

Temperature mapping study and validation are mainly applicable to the pharmaceutical industry and food/FMCG industry. It helps us to analyze and ensure the uniformity of temperature distribution across all areas of the controlled areas under real-life conditions.

The necessity of Temperature Mapping study

Temperature mapping study is to test whether all areas of your asset maintaining the same temperature as per your requirement. Typically we require temperature mapping study for the following type of assets:

  1. Warehouses normally between 15 to 25 Deg C.
  2. Cold Room normally maintaining a temperature between 2 to 4 Deg C.
  3. Walk-in Chillers or Freezers which will maintain a temperature below zero Degree up to -40 Deg C.
  4. Refrigerators which keep medicines normally between 2 to 8 Deg C.
  5. Cold Storage for food which may have different temperature ranges.
  6. Autoclaves which maintain particular temperature ranges.
  7. Humidity chambers which maintain a particular range of humidity.

  8. Refrigerated Vehicle, Van & Reefers which maintain a temperature range such as 2 to 8 Deg C for medical transportation.
  9. Thermally insulated passive boxes which maintain temperature for a certain duration.
  10. Active refrigerated boxes which are small refrigerators.

We carry out the analysis by analyzing the data under real-time operating conditions. For carrying out a temperature mapping study, we place numerous data loggers in the area. They record the data continuously for a couple of days. We mark the location of such data loggers in a 3D drawing. This will become part of the report.

All operations like loading, unloading, forklift movement etc. will happen as normal. We record all such actions to the extent possible. We analyze all such data and prepare analysis and graphs. Thus we analyze the temperature uniformity across the entire area. We will compare any abnormal variations with the real-time operations that happened at those particular times. We identify hot spots and cold spots in this study and we recommend corrective actions.

Temperature & Humidity Mapping Study

For certain assets, you have to maintain humidity within permitted levels. eg. DHA, Dubai specifies that warehouses storing medicines should maintain humidity below 65% RH. In this case, we have to test the distribution of humidity also along with the temperature. Hence we call it as Temperature & Humidity Mapping study.

We have to carry out the temperature study at least in two climatic conditions ie. Summer and winter. This will provide a detailed analysis of the area across various climatic conditions.

Results of the Temperature Mapping Studytemperature-mapping-study-procedure-flow-chart

Apart from certification, various recommendation including the following will form part of the report:

  1. Are there any hot spots in the enclosed area?  Are they rectifiable? If not, we have to isolate this area. Thus the client does not store sensitive items in this area.
  2. If power fails how long the area is safe for the stored goods? This testing helps the customer to understand the required actions in case of a power failure.
  3. We can decide the location for placing your Sensors or recording instruments for continuous monitoring.
  4. How many people and machinery can occupy the area simultaneously?
  5. Any difference in behaviour in Summer and Winter?
Identifying Hot spots and cold spots in a Warehouse, Cold room, walk-in freezer etc.

We determine hot spots and cold spots of the area from the results of the temperature mapping study. As the name indicates, a hot spot means the hottest point inside the area. The cold spot is the coldest recorded point. After identifying the hot spot and cold spot, the client has to install continuously monitor these points using real-time temperature monitoring systems.

What is the difference between Temperature Mapping Study and Validation?

Temperature Mapping study is the study and analysis as explained above. This will provide a detailed analysis report for your enclosed area. This report provides confidence that the area is capable of maintaining the correct temperature.

Validation is mainly applicable to various systems used for controlling and monitoring of the controlled area. Validation of Electronic recording systems is as per 21 CFR part11. This is the process of Validation. The mapping study also may be part of the whole process. The electronic instruments should be as per the international regulations such as 21 CFR Part 11.

Temperature mapping study is known as Thermal mapping study and Temperature validation is known as Thermal validation as well.

What is 21 CFR Part 11?

In general terms, this stipulates compliance of the electronic recording instruments. This is applicable to all manufacturers and distributors of medicines, vaccines and related products.

For life sciences, this refers to the recording of various critical data through all stages of manufacture, storage and distribution of goods so that all recorded data is accurate.
