Abstract
Abstract A portable, fire-resistant barrier for the containment of marine oil spills comprises a continuous length of interwoven high-temperature resistant yarns and metallic wires, coated with a high-temperature resistant synthetic polymeric resin. The woven fabric barrier is buoyed by fire-resistant buoys and stabilized with ballast.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
A fire-resistant, portable, barrier for the containment of marine oil spills, which comprises; (A) a continuous length of a fire-resistant fabric comprising interwoven yarns of heat-resistant material, coated with a liquid-impermeable film; said fabric being impermeable to a hydrocarbon petroleum oil; (B) a plurality of buoyant bodies attached to said fabric in a quantity and at positions sufficient to buoy the length of fabric on a body of water; and (C) means for stabilizing the length of fabric when buoyed upon said body of water.
Claim 2
Dependent Claim
