Video: Methods of visualization testing for hotel smoke removal systems

Learning objectives

• Understand varying types of smoke evacuation systems as they relate to architectural factors.
• Identify the benefit of thermally assisted smoke plume generation for a high ceiling environment.
• Learn the use, control and limitations of theatrical fog generators for field performance testing.
• Identify the benefits of varying types of smoke generation, and a comparison of smoke versus fog generation.

This presentation illustrates methods of conducting smoke removal visualization testing in a hotel environment: atrium, ballroom and corridor. In this review and discussion of an actual field performance test, we explore the smoke generating equipment, effects on field of view, and the factors that helped decide which was the best solution for each scenario.

This presentation illustrates methods of conducting smoke alarm and initiation and subsequent smoke removal visualization testing in a hotel environment. The discussion of an actual field performance test will include pictures of the smoke generating equipment, effects on field of view for each, and explore these demonstration options for owner review and acceptance of their smoke removal systems via direct observation testing. Three methods used to generate smoke for three different evacuation system scenarios at a Marriott Hotel will be discussed. One option uses an inline fan and thermally generated plume along with smoke candle generation to trigger and demonstrate a 16-story atrium smoke removal system. A second option uses an inline fan along with smoke candle generation to trigger and demonstrate a ballroom smoke removal system. A third uses a theatrical fog generator to demonstrate the smoke removal capabilities in a more confined environment of a hotel corridor. The session will discuss construction and design considerations of the various methods as they relate to the architectural constraints, the theory and application of smoke generation methods, and the factors that helped decide which was the best solution for each scenario.
