ABSTRACT:
A device for containing and extinguishing fires and for preventing fires comprises a double-layer plastics foil consisting of polyethylene or polyproplene which contains flame-smothering or flame inhibiting additives, the foil being intended in use to be laid upon burning or endangered objects to form an air-excluding protective layer which covers all irregularities in sealed manner due to the pliability of the foil.
The double-layer foil is produced by blowing on an extruder, flame-smothering or inhibiting additives such as granular antimony being added to the foil material. Additives are preferably added which enter into a homogeneous combination with the foil material.
