Intent
Intent 1: 
To exempt certain interconnected floor spaces from the requirements of Sentence 3.2.8.1.(1) and Articles 3.2.8.3. to 3.2.8.9., which would otherwise require a vertical fire separation or certain fire protection measures, if:
  • the location and number of interconnected floors is limited, which will minimize:
    • vertical fire spread, and
    • delays in emergency responder access and evacuation of occupants,
  • the openings through the floor are used only for stairways, escalators or moving walks, or the interconnected floor space is sprinklered, which will minimize vertical fire spread,
  • the interconnected floor space contains only certain major occupancies, which will minimize fire risks, and
  • the building area is limited, which will minimize delays in emergency responder access and evacuation of occupants.
