Final answer:
The minimum height that tabletop equipment must be raised if it's not sealed to the counter is typically 3 inches.
Step-by-step explanation:
When tabletop equipment is not sealed to the counter, it needs to be raised to a certain height to prevent any objects from falling off the edge. The minimum height required is typically dependent on the size of the equipment and the potential for objects to roll off. In general, a height of 3 inches would be sufficient to ensure that items do not fall off the table.
In order to determine the exact height needed, you can perform a simple experiment. Lift the top of the pipe as high as it will go and measure the vertical height of the top of the pipe above the tabletop. This measurement will give you an idea of the minimum height required to prevent objects from rolling off the table.
By following this guideline and raising the tabletop equipment appropriately, you can ensure the safety of the items on the table and prevent any accidents or damage.
