Abstract
Apparatus for temporary containment of chemicals escaping from end members of a cylindrical container storing pressurized chemicals includes a plate, that can fit within the constricted walls of the ends of the cylinder and an inflatable tube around the edge of the plate. The tube, when inflated, will support the plate against the edges of the cylinder and contain the gas between the containment apparatus and the end members of the container. The repair device further includes a locking mechanism for positioning the plate with respect to threads of the cylinder and for preventing release of the plate in the event of deflation of the tube. A (CO.sub.2) pressurized gas capsule can be included to provide the pressure to expand the tubing. The plate can further include a valve for eventual release of the contained chemical at a convenient location.
