 9.10.16.1. Required Fire Blocks in Concealed Spaces

A building’s overhanging #eaves and #appendages, such as exterior #passageways, #balconies and #canopies, create spaces where fire can spread horizontally within concealed spaces. Vertical fire blocks are, therefore, required at horizontal intervals of not more than 20 m (65 ft. 7 in.), and at locations where the construction extends across the ends of fire separations, such as in row housing with gambrel-type #roofs (Figure 9.10.-32). This requirement applies to both #sprinklered and unsprinklered #buildings.
