What is the required clearance from a steel hood to combustibles?

• A. 12 Inches
• B. 24 Inches
• C. 18 Inches
• D. 36 Inches

Answer: (C)

The required clearance is eighteen inches. This gap between a steel hood and any combustible surfaces helps limit heat transfer and reduce the risk of ignition from radiant heat or grease-laden vapors, while also allowing space for cleaning and maintenance. NFPA 96 and many fire codes specify this distance as the standard practice for kitchen hoods. A smaller distance, like twelve inches, would raise the fire risk, while larger clearances (twenty-four or thirty-six inches) are typically not required unless a specific condition calls for it.
