Abstract:
1. A system comprising first and second fire-resistant parts for at least temporary fire-resistant sealing of an opening in a wall in which at least one transport device has been fed through, or will be fed through, each of the first and second parts being at least partly placeable in the opening, the first parts being designed to at least partly envelop the transport device and the second parts being designed to be placed in direct contact with and between the first parts and/or in direct contact with and between the first parts and an inner wall of the opening to at least virtually completely seal the opening, the first parts being substantially manufactured from a fire-resistant rubber and/or a fire-resistant thermoplastic, or a combination thereof, the second parts being manufactured from a fire-resistant material based on an elastomeric foam with a substantially closed cell structure, the foam including at least one crust-forming, fire-retardant material, wherein the crust-forming fire-retardant material has been chosen from polyammonium phosphate or melamine phosphate, and wherein the crust-forming fire-retardant material is present in such an amount that a fire retardant crust is formed on a side of the foam when exposed to a fire.
