The information in this guide serves to define the intended function of Smoke Control System
Equipment and also explain what operational and performance requirements are necessary for
equipment listed under the UL listing category of UUKL.
IMPORTANT: Smoke control systems must be designed to meet the custom
needs of a particular building and its occupants. This document
illustrates some basic, common smoke control applications, but is
not in lieu of a properly engineered smoke control system,
designed by a qualified Fire Protection Engineer.

Many people are not aware that smoke is the major killer in fires. Smoke can travel to places in
buildings that are quite distant from the scene of the fire, threatening life and property. It can fill
stairwells and elevator shafts, blocking both evacuation and firefighting. Smoke control systems
reduce the number of smoke-related injuries and deaths. In addition, these systems reduce property
loss and damage caused by smoke.
Smoke control makes use of powered fans to produce air pressure that can control smoke
movement. Air pressure has been used in laboratories for over fifty years to prevent airborne
bacteria and poison gases from migrating from one area to another. It has also been used to control
the entrance of dust and other contaminants into computer rooms; and used in hospitals to prevent
the migration of harmful bacteria into sterile areas.
This chapter gives you an overview of smoke-control systems, including a discussion of the
driving forces of smoke movement, the principles of smoke control, and the concepts of smoke
control system design.
