ABSTRACT:
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.
