In general, a grease duct system serving a Type 1 hood must have a minimum clearance of how many inches from gypsum board wallboard attached to noncombustible structures?

• A. 2 inches
• B. 3 inches
• C. 4 inches
• D. 5 inches

Answer: (B)

A grease duct system that serves a Type 1 hood is specifically designed to handle grease-laden vapors from commercial cooking operations. The minimum clearance requirement from gypsum board wallboard attached to noncombustible structures is set at 3 inches. This clearance is crucial for fire safety and to prevent heat transfer to nearby combustible materials. Reducing the clearance could lead to overheating and potential ignition of the wallboard, posing a significant fire risk in the kitchen area where the hood operates. The 3-inch clearance allows for sufficient space for the dissipation of heat and reduces the chances of fire hazards, ensuring compliance with safety standards and building codes. This requirement is part of fire safety regulations to prevent fires from spreading and to maintain safe operation of kitchen ventilation systems.
