• Description:
  In response to a request from a representative of the American Federation of State, County, and Municipal employees which represented employees of the District of Columbia School of Law, an investigation was begun into health problems experienced by building occupants at the School of Law (SIC-8221), Washington, DC. Numerous reports of illness, poor ventilation, visible particulate from overhead vents, and conditions of fatigue and dizziness affecting both students and employees were reported. Two constant volume air handling units service the six story building. One unit supplied the exterior zone of the building, delivering ventilation through high pressure induction coil units in each perimeter office or room. The interior zone was serviced by a much larger unit that supplied air through ducts. On the day of the inspection, sufficient outside air was being provided to the building, with the exception of classroom 102. Carbon-dioxide (124389) measurements taken inside classroom 102 exceeded the 1,000 parts per million reference level. Temperature and relative humidity levels were acceptable. Most return air pathways were blocked by floor to slab interior walls, which would likely limit proper air distribution and circulation. Air vents on some perimeter fan coil units were also blocked. The authors recommend that the return air path restriction be eliminated, and an indoor air quality management plan be implemented. Housekeeping throughout the building should be improved. Use of pesticides inside the building should be reevaluated.
