Abstract: 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.
