Chapter 1 Smoke control overview Smoke is one of the major problems created by a fire. Smoke threatens life and property, both in the immediate location of the fire and in locations remote from the fire. The objectives of smoke control include: • Maintain reduced-risk escape route environments • Diminish smoke migration to other building spaces • Reduce property loss • Provide conditions that assist the fire service • Aid in post-fire smoke removal Smoke consists of airborne solid and liquid

Chapter 1 Smoke control overview Methods of smoke control Smoke control system designers use five methods to manage smoke. They use the methods individually or in combination. The specific methods used determine the standards of design analysis, performance criteria, acceptance tests, and routine tests. The methods of smoke control consist of: compartmentation, dilution, pressurization, air flow, and buoyancy. Compartmentation method The compartmentation method provides passive smoke protect

Applications of smoke control methods A disadvantage of the airflow method is that it supplies increased oxygen to a fire. Within buildings, the airflow method must be used with great caution. The airflow required to control a wastebasket fire has sufficient oxygen to support a fire 70 times larger than the wastebasket fire. The airflow method is best applied after fire suppression or in buildings with restricted fuel. For more information on airflow, oxygen, and combustion, refer to Hugge

Chapter 1 Smoke control overview Zoned smoke control cannot limit the spread of smoke within the smoke control zone. Consequently, occupants of the smoke control zone must evacuate as soon as possible after fire detection. Figure 3: Sample arrangements of smoke control zones + : Represents high-pressure zone – : Represents low-pressure zone When an HVAC system serves multiple floors (Figure 4 on page 7) and each floor is a separate zone, the following sequence provides smoke control: 1.

Applications of smoke control methods Figure 4: Sample HVAC operation during smoke control Note: For simplicity, Figure 4 does not show the ducts on each floor or the penthouse equipment. When an HVAC system serves only one smoke control zone, the following sequence provides smoke control: 1. In the smoke control zone, the return/exhaust fan activates, the supply fan deactivates. 2. The return air damper closes, and the exhaust damper opens (optionally, the outside air damper closes). 3. In

Chapter 1 Smoke control overview If the technique employs modulated supply airflow, a fan provides at least minimum pressure when all stairwell access doors are open. Either a single-speed fan with modulating bypass dampers or a variable frequency drive varies the flow of air into the stairwell to compensate for pressure changes. If the technique employs over-pressure relief, a damper or fan relieves air to the outside to maintain constant pressure in the stairwell. The amount of air relie
