Grease filters shall be equipped with a grease drip tray beneath their lower edges. What part of the filter does this apply to?

• A. top edges
• B. sides
• C. upper surfaces
• D. lower edges

Answer: (D)

The idea being tested is preventing grease from dripping into the hood and ductwork. Grease that collects on the filter tends to run downward due to gravity, so placing a grease drip tray beneath the lower edges of the filter catches those drips before they can fall into the exhausting system or onto surfaces. A tray at the bottom edge is what intercepts the downward flow; trays on the top, sides, or upper surfaces would not capture the drips effectively since the grease moves downward from the filter. Keeping the tray under the bottom edge also makes it easy to remove and clean, helping maintain safety and performance.
