Throwing out all food in a refrigerator that has stopped working overnight is an example of a

Corrective Action.

Explanation:

In quality management, a corrective action is an action or effect implemented to eliminate the causes of a nonconformity, defect or undesirable situation detected. It is precisely for this reason that we can classify the action reported in the above question as an example of corrective action. This is because if the refrigerator stopped working all night, the food being stored there was exposed to a temperature outside the proper temperature for its storage.

Due to temperature, many foods may have been spoiled or unfit for food due to the proliferation of harmful microorganisms that have invaded the food due to improper storage temperature.
