It is not feasible to provide dynamic smoke exhaust for the entire hall in some terminals or malls with a large volume space. The cabin design is commonly used with a ceiling roof covering the retail areas, giving smaller shops. Active fire protection systems, including dynamic smoke exhaust and fire suppression systems, are expected to be installed.

In this paper, design aspects of the smoke control system in such retail shops will be discussed. It is found that fire suppression systems should be provided. The new concept of using a water mist system, as reported earlier, will be further confirmed. Full-scale burning tests are useful in assessing the performance of water mist systems in such a shop fire. The research fire field model Fire Dynamics Simulator FDS is applied to simulate the fire environment with and without the roof and the roof with downstands.
