How much space should tabletop equipment have between its base and the surface it rests on?

Tabletop equipment should have at least four inches of space between its base and the surface it rests on to ensure proper air circulation and to facilitate cleaning underneath. This space helps prevent contamination and allows for adequate airflow around the equipment, which is essential for maintaining safe operating temperatures. Moreover, this clearance minimizes moisture accumulation and helps ensure that any spills or debris can be easily cleaned, thus it contributes to overall food safety and hygiene standards in the food service environment.
