Minimum height for steel or tempered grease baffle plates between the surface flames

Minimum height for steel or tempered grease baffle plates between the surface flames

• A. 8 Inches
• B. 6 Inches
• C. 10 Inches
• D. 12 Inches

Answer: (A)

This tests understanding of the safe clearance between the cooking surface flames and the grease baffle plates used in a kitchen hood. The minimum height is eight inches because this gap provides a protective buffer that reduces radiant heat exposure to the baffle and minimizes direct flame impingement on grease-laden surfaces. That spacing helps prevent grease ignition and supports proper hood airflow and filtration performance. If the distance were smaller, the baffle could overheat or be exposed to higher heat, increasing fire risk. If it were larger, it would unnecessarily alter hood design and airflow efficiency without additional safety benefit. This eight-inch standard aligns with common practice in NFPA 96 restaurant ventilation guidelines.
