There are several foods that cannot be preserved in the fridge, such as: dry food (cereals, rice, pasta, flour), cans, products in glass containers before opening (e.g. jams, honey) and several types of juices and beverages. There are rules to follow for these categories as well.
Make sure the storage area is dry, cool and free from strong smells.
Store foods or beverages away from any cleaning products or chemicals.
Protect foods by keeping them in sealed bags or containers. This will keep them fresh longer and prevent the mix of smells, as well as any raids by insects or ants.
Never store flour on the floor. It can attract ants, mice and other unwanted visitors.
Always read the user instructions. Some foods must be refrigerated once opened.
