From page 71...
... 113 Explosive Containment Room B Observation Corridor Buffer Storage Area Chemical Assessment Lab Comments GB agent migration from MDB filter into vestibule. Probable cause of the agent readings in the containment vestibules was the method used for placing the filter units off-line when not in service.
From page 72...
... Agent vapor migration to Observation Corridors due to HVAC failure during global loss of power. Incomplete drain of an MC-1 bomb allowed excess of agent to enter metal parts furnace.
From page 73...
... ACAMS alarmed in the DFS due to the interruption of the airflow. As a precaution TOCDF suspended munition processing and RTAPS deployed with negative readings.
From page 74...
... No agent or munitions involved. Operational shutdown - natural gas supplier Questar, informed DCD due to unseasonably cold weather gas supply was low.
From page 75...
... Technical investigation conducted and procedures changed. During feed rate capacity test the primary burner locked out on flamed failure.
From page 76...
... Maintenance personnel enter toxic cubicle to replace an instrument and valve. When one of the agent transfer lines was cut, a dark oily substance leaked out.
From page 77...
... Allagent vapors maintained under engineering controls. Investigation conducted and corrective actions taken - install top feed gate brushes and program change to Logic Controller.
From page 78...
... Blood draws on 29 people indicated no depression of CHE. Technical investigation completed with recommended procedural changes.
