A safety shield for containing and deflecting a fluid leaking from a flanged pipe coupling in the form of an arcuate strip of transparent fluoropolymer. The strip has a flange along each circumferential edge which is integral with the strip and extends radially inwardly thereof. The strip is of sufficient length to encase the circumference of the pipe coupling flange to which it is applied with the opposing ends overlapping and fastened together. The flanges closely engage the radial surfaces of the coupling flanges. The safety shield is obtained by heat-shrinking a heat-shrinkable tube of fluoropolymer while restricting radial shrinkage thereof except the marginal edge portions which become the flanges.

A method for making a safety shield which comprises subjecting an annular section of a heat-shrinkable tubing formed of a fluoropolymer to shrinking conditions while substantially restricting radial shrinkage thereof except along marginal edge portions of said section to form flanges extending radially inward of said section, cooling said section and cutting said section longitudinally thereof to form an arcuate strip having flanges integral with and extending along each longitudinal edge of said strip, and providing means at the end edges of said strip for connecting the opposing ends of said strip in overlapping relation.
