When connecting components in an exhaust system, all directions must guarantee what kind of integrity?

The concept of structural integrity is crucial when connecting components in an exhaust system, especially within the context of commercial cooking operations as outlined by NFPA 96. Structural integrity ensures that the exhaust system can support the weight of the components, withstand forces such as wind or seismic activity, and function effectively under operating conditions. This is vital to prevent failures that could lead to system collapse, which would compromise the safety and efficiency of the ventilation system.

In commercial cooking operations, where high temperatures and various cooking byproducts are present, maintaining structural integrity means that the exhaust system will remain intact and function as intended. It also helps ensure that the system can handle the stresses applied during normal use as well as any maintenance activities.

Other aspects, such as visual, acoustic, and thermal integrity, while they may play roles in the overall performance and effectiveness of an exhaust system, do not specifically address the fundamental requirement for the system's components to remain securely connected and functional under loads and stresses that can occur in a commercial kitchen environment. Understanding structural integrity in this context helps in designing and maintaining safe cooking operations compliant with NFPA standards.
