OSCs Pete Stevenson and Valeriy Bizyayev arrived at the site around noon and discovered that the spill was from a broken thermometer in the file room. The thermometer was removed by an unknown person but mercury has been tracked onto carpeting in the hallway and nearby work areas. The highest reading was 140,000 ng/cubic meter of air near a piece of broken glass on the floor but much lower readings were recorded in the breathing zones.
