Abstract
In response to a request from the staff, an evaluation was undertaken by NIOSH to examine occupant exposures to bioaerosols, resulting from an uncapped sewage pipe above the National AIDS Program Office (NAPO) (SIC-9431, SIC-9199), located in the Hubert H. Humphrey Building, Washington, DC. The office had a staff of nine and was one of many federal offices within the building. Contractors had apparently removed a section of sanitary drain pipe, which resulted in an overflow of sewage into the ceiling plenum and the collapse of the ceiling. Carpeting and building furnishings were contaminated with sewage. Water damaged building materials and furnishings were present at the time of the survey. No significant differences in indoor versus outdoor air samples were noted. No bacterial cultures revealed any organisms which were associated with building related illnesses. The authors conclude that building related illness was not identified in the affected area. The condition of condensate drain pans in air handling units and the presence of drip collection pans in the return air plenum suggested the need for increased maintenance to avoid conditions favorable for microbial growth and amplification. The authors recommend that necessary repairs to the building be made, moisture source be removed from air handling plenums, and repairs be made to the heating, ventilation and air conditioning system.
