How often must refrigerators be checked to ensure the temperature stays in the appropriate range?

Refrigerators used for storing temperature-sensitive items, particularly in air freight operations, must be monitored regularly to ensure that they maintain the appropriate temperature range. Checking the temperature every 12 hours is a best practice that balances the need for safety with practical monitoring frequency. This timeframe allows for adequate oversight without overwhelming personnel with excessive checks, helping to ensure that any fluctuations in temperature can be identified and addressed promptly. Regular checks are crucial for preventing spoilage and maintaining the integrity of sensitive cargo, which is particularly important in the context of air freight where items can be exposed to varying conditions.

While more frequent checks, such as every 8 hours, may offer tighter control, they may not be necessary in all situations, as many facilities may successfully manage temperature consistency with 12-hour intervals. Conversely, less frequent checks, such as every 24 hours, may increase the risk of overlooking critical temperature deviations that could compromise the safety of stored goods.
