ABSTRACT:
A protective shield is disclosed for preventing materials which spray through the gap in an opened flange connection from striking the person who opens the connection. The shield is made up of an inner ring and outer ring, joined only at their ends. When the shield is placed over a flange connection, the ends of the rings are spaced apart slightly so that the flange gap is not completely covered. The shield is positioned so that the space between the rings is on the opposite side of the flanges from the person who is opening the connection. As the connection is opened, any material which might spray through the flange gap is confined by the inner ring, such that it will flow around the flange and discharge through the space between the rings.
