Abstract
A system and method for inhibiting gas release while accessing a pressurized gas pipeline includes a magnetic plug holder for magnetically engaging a pipe plug to a rod. A housing is sealingly engaged to a valve attached to the pipeline, and the rod is movable through the housing in a sealing fashion such that the plug holder can be moved linearly and rotationally relative to the housing. The housing can be sealingly attached to a portion of the valve, the valve can be opened, and the plug holder with a threaded plug magnetically engaged thereto lowered through the valve. The rod can be rotated from outside the housing to thread the plug into the threaded hole in the pipeline.
