What type of smoke management method is referred to as smoke purging, smoke removal, smoke...

Smoke purging, smoke removal, smoke exhaust, or smoke extraction are different terms for the same type of smoke management method, which is airflow. Airflow is the method of controlling smoke by creating a flow of air that either pushes or pulls the smoke away from the desired areas. Airflow can be achieved by natural or mechanical means, such as vents, fans, or dampers. Airflow can also be used to create a smoke layer above the occupant level in large spaces, such as atriums or warehouses, by exhausting the hot smoke and supplying fresh air below the layer.References:Smoke Extraction System - NAFFCO Smoke Management;Post-Fire Smoke Purge Systems: When Are They Required? - NY Engineers; NFPA Fire Protection Handbook, 21st Edition, Chapter 9, Section 9.2.1.
