A safety shield for capturing corrosive fluids escaping from joints or valves in piping systems consists of first and second shroud members releasably joined together to form an enclosed chamber in assembled position about the joint or valve. The chamber includes at least one aperture which is sized and shaped for mating engagement around the pipe. Corrosion resistant gasket members interposed between the first and second shroud members and between the pipe and the at least one aperture render the enclosed chamber vapor tight in the assembled position. The chamber may further include at least one other aperture sized and shaped to receive the operating stem of the valve therethrough, and a corrosion resistant gasket interposed between the valve stem and the at least one other aperture for forming a vapor tight seal without interfering with the operation of the valve. The first and second shroud members are releasably held together by adjustable bands which are tightened around the outer periphery of the shroud members so as to exert a substantially uniform pressure along the joining region between the shroud members. The safety shield may also include one or more outlets for discharging any fluid which may accumulate in the enclosed chamber.

A safety shield for capturing a corrosive fluid escaping from a joint in a pipe, comprising first and second shroud members formed from a corrosion resistant material, connecting means for releasably joining said first and second shroud members together along a joining region to form an enclosed chamber in assembled position about said pipe joint, corrosion resistant gasket means arranged between said first and second shroud members for rendering said joining region vapor tight in said assembled position, at least one aperture in said enclosed chamber sized and shaped for mating engagement around said pipe, corrosion resistant sealing means for forming a vapor-tight seal between said pipe and said at least one aperture, said sealing means having first and second ends and being installed around said at least one aperture to form a continuous circle with said first and second ends in overlapping engagement, said sealing means being joined to said gasket means in overlapping relationship to render said enclosed chamber vapor tight in said assembled position, and outlet means for discharging any said fluid accumulated in said chamber.
