scope:

This standard provides methodologies for estimating the location of smoke within a large-volume space due to a fire either in the large-volume space or in an adjacent space.

These methodologies comprise the technical basis for assisting in the design, installation, testing, operation, and maintenance of new and retrofitted smoke management systems for the management of smoke within the space where the fire exists or between spaces not separated by smoke barriers.

Buildings within the scope of this standard include those with atria, covered malls, and similar large-volume spaces.

This standard is not intended to apply to warehouses, manufacturing facilities, or other similar spaces.

This standard does not provide methodologies to assess the effects of smoke exposure on people, property, or mission continuity.

The algebraic approaches to smoke management contained in this standard assume either that the smoke removal will be by mechanical means or that the smoke will fill the large space.

Purpose.

The purpose of this standard is to provide requirements for implementing smoke management systems to accomplish one or both of the following:

(1) Maintain a tenable environment in the means of egress from large-volume building spaces during the time required for evacuation

(2) Control and reduce the migration of smoke between the fire area and adjacent spaces

Specific design objectives are established in other codes and standards.
