Can ductwork that is subject to corrosion come into contact with building surfaces?

• A. Yes, it is permissible
• B. No, it is not allowed
• C. Yes, with special approval
• D. Only in specific circumstances

Answer: (B)

Ductwork that is subject to corrosion should not come into contact with building surfaces. This is crucial for preventing further degradation of materials, potential fire hazards, and maintaining the integrity of the ventilation system. The NFPA 96 Standard emphasizes the importance of using durable materials that can withstand the environments they are placed in, particularly in commercial cooking operations where grease and other corrosive elements can significantly affect both the ductwork and surrounding structures. When duct systems come into contact with building surfaces, the risk of corrosion increases, which can lead to leaks or failures in the system, compromising air quality and safety. Additionally, allowing corrosive ductwork to touch building surfaces could lead to structural damage or fire risks. For these reasons, it is essential to maintain a separation to ensure the safety and effectiveness of the ventilation system in commercial cooking environments.
