locking refrigerator doors when leaving home for an extended period of time was not a common practice. Refrigerators typically do not come with locks designed to secure the contents inside.
Most people rely on the doors of the refrigerator and freezer to seal tightly on their own without the need for additional locking mechanisms. Modern refrigerators are designed with strong magnetic seals to keep the doors closed and maintain the proper temperature to preserve the food.
However, it's worth noting that individual practices may vary depending on cultural norms, personal preferences, and specific situations. Some people might take extra precautions and secure their refrigerators in various ways, such as using child locks or straps if they have young children at home.
If you are concerned about the security of your fridge's contents while you're away, ensure that perishable items are consumed or properly stored, and set the refrigerator to a slightly higher temperature to conserve energy while it's not in use. Additionally, secure your home overall by ensuring all doors and windows are locked and consider using a home security system if you have one.
