What is the minimum distance required between the lowest edge of a grease filter and a cooking surface with exposed flame?

The minimum distance required between the lowest edge of a grease filter and a cooking surface with exposed flame is 2 feet. This requirement is established to ensure safety in commercial kitchen environments, where grease buildup can pose a significant fire risk. A distance of 2 feet helps prevent the accumulation of grease on the filter from igniting due to heat or flames from the cooking surface.

Grease filters are designed to capture smoke and grease particles to improve air quality and reduce fire hazards, but if they are positioned too close to a source of heat, they can become a fire hazard themselves. By maintaining a minimum distance, the risk of flames reaching the filter and causing a fire is minimized, thus promoting a safer cooking environment.

Understanding this distance is crucial for compliance with mechanical codes and ensuring the safety of kitchen operations.
