What is the minimum distance that a floor shall be protected by millboard and sheet metal around a food service appliance installed on a combustible floor?

The minimum distance that a floor must be protected by millboard and sheet metal around a food service appliance installed on a combustible floor is established to ensure safety and reduce the risk of fire hazards. A distance of 6 inches is deemed appropriate as it provides adequate heat shielding to protect the combustible materials from temperatures that may rise due to cooking operations. This specification helps to prevent any ignition of the floor material, which could lead to dangerous fire situations in a kitchen or food service environment.

This regulation aligns with safety standards that recognize the importance of having a controlled buffer zone around appliances that generate significant heat. Adhering to this requirement is crucial for maintaining a safe operating environment in food service facilities.
