On July 28, 1998, a total flood type carbon dioxide fire extinguishing system discharged without warning into an electrical room at the Idaho National Engineering and Environmental Laboratory (INEEL).  The carbon dioxide system control panel was a Notifier model AFP-200.  Workers were doing routine maintenance in the room.  One fatality and a number of injuries resulted from this accident.
