Objective | OP3 Protection of Adjacent Buildings from Fire |
Attribution | |
Application | Application 1: Calculation of the maximum aggregate area of unprotected openings, where all rooms, including closets
and bathrooms, that are adjacent to the exposing building
face and that have unprotected openings are sprinklered, notwithstanding any exemptions in the
sprinkler standards referenced in Article 3.2.5.13., in buildings to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9] that are sprinklered.
Exceptions:
except as stated in Sentence 9.10.15.1.(1), which applies to buildings that contain only dwelling
units and have no dwelling unit above
another dwelling unit.

Intent | Intent 1: To supersede the requirements of Sentence 9.10.14.4.(1),
which would otherwise require certain maximum areas of unprotected openings,
and permit a doubling of unprotected openings if certain conditions are met
[i.e. the building and certain rooms are sprinklered]. This
is to limit the probability that a fire in the subject building will not be
suppressed or controlled, which could lead to the spread of fire from the
subject building to an adjacent building during the time required for emergency
responders to perform their duties, which could lead to damage to the adjacent
building.
Intent 2: To supersede the requirements of the standards referenced
in Article 3.2.5.13. by requiring certain rooms to be sprinklered.
