Gas cooling to control the fire environment in compartments

Published: 18 November, 2010

In today’s built environment, a compartment fire develops quickly. Synthetic materials used in furnishings and interior finish have a much higher heat of combustion and heat release rate than the natural materials found in the built environment of the 1950s and 1960s. When a compartment fire develops, buoyant, hot smoke and entrained air form a layer at the ceiling and begin to fill the compartment. As the depth of the layer increases, the hot smoke and air begins to flow out through the opening into adjacent compartments, writes Chief Edward E Hartin, (MS, EFO, MIFireE, CFO) of Central Whidbey Island Fire & Rescue in the State of Washington, US, and owner of CFBT-US, LLC, an international fire behaviour training and related consulting service.
