In response to a request from a group of employees at the District of Columbia Board of Parole (SIC-8322), Washington, DC, an investigation was begun into possible hazardous conditions into which employees were being placed when they were dealing with parolees with active tuberculosis. In August of 1992, 54 Board of Parole employees supervised about 4,200 parolees from this office location. Each officer had approximately 225 parolee visits per month. Overcrowding in the waiting areas was frequent. An evaluation was made of the ventilation system at the facility. Outside air intake on the first floor, and possibly the third floor, did not meet the minimum requirements. Afternoon carbon-dioxide (124389) levels exceeded 1,300, 875, and 1,000 parts per million (ppm) on the first, second, and third floors, respectively. Of the 51 employees, 67% completed a self administered questionnaire. All respondents recalled at least one tuberculin skin test prior to November 1992. None of the respondents had been diagnosed with active tuberculosis. Two employees whose previous skin tests had been negative had positive tuberculin reactions. The authors conclude that these employees may have an added risk of tuberculous infection due to the fact that parolees are at increased risk for developing active tuberculosis, and the limitations of the building's ventilation system. The authors recommend that a tuberculosis screening program be established for employees. Improvements in the ventilation system should be made.
