<p>The invention relates to a device for containing and extinguishing fires and for preventing fires, which takes the form of a double-layer synthetic plastics foil, such as polyethylene or polypropylene which contains flame-smothering or inhibiting additives and is intended in use to be laid upon the burning or endangered objects to form an air-excluding protective layer which due to the flexibility of the foil covers all irregularities in sealed manner. The double-layer foil of polyethylene is produced by blowing on an extruder, flame-smothering or inhibiting additive such as antimony granulate being added to the material. Additives are preferably added which enter a homogeneous combination with polyethylene.</p> |
