Code Articles

Smoke management is a term used to describe the methods implemented to passively or actively control the movement of smoke within the built environment in the interest of providing safety to occupants, fire fighters and property. Smoke management methods include compartmentation, pressurization, airflow and buoyancy. It has been used to simulate smoke movement in multizone facilities, to analyze the performance of smoke control systems including stairwell pressurization systems and to aid in the performance of tenability "occupant safety" analysis. Analysis of smoke management requires the consideration of the interaction of the many different building characteristics and driving forces that affect smoke movement.
