Summary
BSEE investigates a high-pressure gas release on Atlantis following installation of unsuitable Teflon seals during transmitter replacement. Findings address contractor oversight, procedural knowledge, training and safety culture. Buyback gas prolonged the release, while bypassed shutdown functions and poorly positioned detectors undermined detection and emergency response.
