Intent

Intent 1:

To exempt certain ducts from the application of Sentence 3.1.8.7.(2), which would otherwise require smoke dampers or combination smoke/fire dampers, on the basis that:

  • the lack of smoke dampers or combination smoke/fire dampers in this case will not lead to a significant spread of smoke,
  • accidental closing of the smoke dampers or combination smoke/fire dampers by the cooking operations would lead to an undue hardship to the operations, or
  • the smoke dampers or combination smoke/fire dampers and their operating parts could collect grease, be very difficult to clean, and add to the fire hazard.
