We have a scenario where we have a series of Restaurant kitchen exhaust hoods connected to a common exhaust duct in a mall. The building is sprinklered and wet chemical fire protection is provided to individual hoods. NFPA 96 allows the use of NFPA 13. As the building is sprinklered can we use 7.10.2.2. from NFPA 13 to eliminate the requirement of protecting the common exhaust duct seeing that we have listed grease filters in the hood.
