- Abstract
- [ABSTRACT IN ENGLISH] Information concerning the use of high-expansion foam has been collected and evaluated and is presented in this summary. The normal pattern of foam expansion depends on certain surface-actant molecules in the foam extract. The presence of pollution in the expansion gases, such as gases from pyrolysis, can, even on a ppm-level, stop the production of foam. Thus fresh air is usually used as an expansion gas and as a consequence the fire room has to be well ventilated when the foam is applied.
