An electrical accident at Technical Area (TA) 53 at Los Alamos National Laboratory affected nine Los Alamos employees, two of whom required hospitalization. The direct cause of the accident was determined to be cleaning fluid sprayed into the air gap between an energized switchgear bus and the grounded enclosure. The aerosolized fluid created a path to ground, resulting in an arc-flash. The root cause was less-than-adequate management of control implementation.
