Lessons Learned - MSFC Building 4672 Pressure Reducing Statin Grayloc Clamp Removal
Year: 1999
Abstract: Description of Driving Event:
On June 29, 1999, personnel were removing a Grayloc blind hub that had been used to temporarily isolate a portion of the gaseous hydrogen system. As a result of a sudden release of 2800 psig gaseous nitrogen, sand and debris kicked up from the concrete pad and caused minor injury to two technicians.
