What is the minimum clearance to combustibles for a Type I hood?

The minimum clearance to combustibles for a Type I hood is 18 inches. This distance is established to ensure that there is a safe buffer between the hood, which is used to ventilate heat, smoke, and grease from cooking equipment, and any combustible materials in the surrounding environment. Adequate clearance is critical for fire safety as it helps to prevent the ignition of nearby surfaces that may be affected by the heat radiating from the hood.

In commercial kitchens, where Type I hoods are frequently used, exceeding this minimum clearance can be beneficial by allowing proper airflow, reducing fire risk, and ensuring compliance with mechanical codes and fire regulations. It is important to follow these guidelines to maintain both safety and compliance with North Carolina Mechanical Code standards.
