Hypoxic Systems

Fire protection through permanent reduction of the oxygen content has become more common in areas such nuclear industry, other industries, museums, libraries, warehouses, etc. The protection level is, however, highly dependent on the selected oxygen percentage which must be balanced against the risk of health effects on people.

There is much research on how different materials behave under fire in normal atmosphere. However, the research on fire in oxygen-reduced environment limited and the lack of knowledge about how materials and actual products behaves in a fire in oxygen-reduced environment.

The project aims to increase the level of knowledge about fire behavior, ignition properties, power development and production of soot by a fire in oxygen-reduced environments. The goal is primarily to quantify the effect of a reduced oxygen environment with respect to heat release, fire risk and the production of gases for various materials and products. This will be linked to physical material properties so that estimates can be made also for non-tested materials. The goal is also to increase knowledge about the production of gases at under-ventilated fires.
