We do not have a checklist, but here are some questions that you can ask:
How they maintain the refrigerators/cold rooms
How do they monitor the temperature of the refrigerators / cold rooms
Are equipment for monitoring temperature calibrated – ask for the certificate of the calibration
What is the principle of the storage – First in first out (FIFO) or First expire first-out (FEFO)?
Is there other special conditions for the refrigerators/cold rooms that need to be monitored (for example: is humidity important to be monitored; if refrigerators are used, is it necessary to ensure the conditions of the room in which the refrigerators are located in order to prevent overheating)
