<p>The invention relates to a fire resistant material based on an elastomeric foam. The invention further comprises a system for sealing off, at least during a fire taking place adjacent the wall, in an at least virtually entirely fire -tight manner, an opening extending through that wall through which a transporting device comprising for instance a cable, duct or pipe ha s been fed, the system being provided with elements manufactured from a fire~resistant material which expands under the influence of temperature increase. In addition, the invention extends to a wall in which such a syste m has been incorporated and a method for sealing off an opening extending through a wall through which at least one transporting device such as a cabl e, duct or pipe has been fed.</p> |
