San Francisco Fire Code § 909.4 [For SF] Analysis

A rational analysis supporting the types of smoke control systems to be employed, the methods of their operations, the systems supporting them, and the methods of construction to be utilized, shall accompany the construction documents submission and include, but not be limited to, the items described in Sections 909.4.1 through 909.4.8.

The design of the smoke control system may incorporate rooms or areas designated as either active zones or passive zones. A passive zone shall be defined as any room/area that uses compartmentation only to prevent smoke migration and does not utilize the methods prescribed under Sections 906, 907, and 908. An active zone shall be defined as any room/area that uses any of the methods prescribed under Sections 906, 907, and 908. Passive zones shall be enclosed by smoke barriers or smoke partitions unless the analysis required by Section 909.4 provides technical justification for the omission of smoke barriers and/or smoke partitions. The fire code official may require a tenability analysis where the design of the smoke control system incorporates passive zones in rooms/areas that would normally be designed as active zones, or where a building that is required to be protected by a smoke control system complying with Section 909 is designed with most or all rooms/areas arranged as passive zones. The tenability analysis shall demonstrate that tenability is maintained within the means of egress and within zones other than the zone of fire origin for the duration required by Section 909.4.6.

Specific Submittal Criteria for Reports, Special Inspections and Final Acceptance Testing of Smoke Control Systems.

Refer to San Francisco Building Department Administrative Bulletin (AB) 047 regarding the design, installation, inspection, and maintenance requirements for any smoke control system provided under the SFFD jurisdiction, as applicable.
