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.
