Recently, a researcher was cleaning the interior of a glovebox window when a glovebox differential pressure alarm was activated. Remaining calm, the researcher visually surveyed the glovebox work area and realized the left glovebox support ring and glove he was working in had detached outward from the glovebox port creating an opening directly into the glovebox. The researcher was able to close the gap between the glove and glovebox by pressing his shoulder into the glove ring while simultaneously pulling the left glove into the box with his right glove. Another staff member in the room notified a Radiation Protection Technician (RPT), who immediately responded and re-seated the glove ring. With the assistance of several other RPTs, the researcher was then able to exit the glovebox safely and with minor contamination on his laboratory coat.
