9.10.12.2. Location of Skylights
(1) Where a wall in a building is exposed to a fire hazard from an adjoining roof of a separate unsprinklered fire compartment in the same building, the roof shall contain no skylights within a horizontal distance of 5 m of the windows in the exposed wall.
In Plain Language
Skylights have location restrictions relative to fire separations and property lines, as set out in this article, limiting fire exposure risk through this roof opening.
