True or False: All interior surfaces of the exhaust system must be accessible for cleaning and inspection.

In the context of the NFPA 96 Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, it is essential that all interior surfaces of the exhaust system are accessible for cleaning and inspection purposes. This requirement is in place to ensure that any grease and other contaminants, which can accumulate and pose a fire hazard, can be adequately removed.

Accessibility for cleaning allows for the effective maintenance of the exhaust systems, reducing the risk of grease buildup that can lead to kitchen fires. Regular inspections help to identify potential problems before they escalate, ensuring the safety of the cooking operations. The emphasis on accessibility in the code reflects the understanding that proper maintenance is crucial for fire prevention in commercial kitchens.

Thus, the assertion that all interior surfaces must be accessible for cleaning and inspection is indeed true, as it is a fundamental requirement of NFPA 96 intended to safeguard against fire risks associated with commercial cooking activities.
