Can duct systems connect with other building ventilation systems without any additional requirements?

Duct systems must be designed to operate independently of other building ventilation systems to ensure that each system can function effectively and safely. The NFPA 96 standard establishes specific guidelines for commercial cooking operations, focusing on the unique fire hazards associated with cooking processes. When duct systems for commercial kitchens connect with other ventilation systems, it can lead to various concerns, including the potential for grease build-up, cross-contamination of air, and a higher risk of fire.

Connecting duct systems without additional requirements may compromise the performance of both the cooking ventilation system and the other building ventilation systems. Therefore, NFPA 96 emphasizes the need for specified separations and containment features when connecting these systems. This ensures compliance with safety norms and enhances the overall fire prevention measures within a commercial cooking environment.
