Apparently, yes. The cabinet has a port to allow the exhaust to be routed into the fume hood plenum, but there is no evidence that this was being used. Our analysis is that the pump was exhausting directly into the cabinet. When asked, the researcher was
not certain whether there was an exhaust tube connected, but there was no evidence of one after the event. The fire department had removed the pump from the cabinet before we arrived on the scene.
