Using an inert gas extinguishing system in historic buildings

Liv Astrid Bergsager of Stord/Haugesund University College in Norway

Historic buildings can be a fire risk and pose a challenge for the choice of extinguishing systems. At this morning’s session on Clean Agents at SUPDET in Orlando, Liv Astrid Bergsager from Stord/Haugesund University College in Norway presented an overview of a study that looked at large air leakages in old buildings and their effects on the extinguishing concentration and hold time. The study examined how long the INERGEN (IG-541) (an inert gas clean agent) extinguishing concentration would be maintained in rooms with a large air leakage. Read an abstract of this presentation, which outlines the test design and methodology as well as test results.
