What is the purpose of cleanouts in grease ducts according to the North Carolina Mechanical Code?

The purpose of cleanouts in grease ducts, as outlined in the North Carolina Mechanical Code, is fundamentally to allow for the removal of obstructions. Grease ducts are crucial components in commercial kitchens where cooking appliances produce grease-laden vapors. Over time, these ducts can accumulate grease, which not only reduces the efficiency of the duct system but can also pose a significant fire hazard.

Cleanouts are strategically placed in these ducts to facilitate maintenance and ensure that any build-up of grease or other materials can be easily accessed and removed. This promotes not only the longevity of the duct system but also the safety of the entire kitchen environment by minimizing the risk of grease fires. Regular maintenance through the use of cleanouts is vital in adhering to health and safety regulations, making them an essential feature in the design and installation of grease duct systems.

While the other options might seem relevant in different contexts, they do not address the primary function of cleanouts in grease ducts. The focus is specifically on maintenance and safety, underscoring the importance of keeping these ducts free from obstruction.
