The airflow distribution system at the State of New Jersey Unemployment Insurance Claims Office in Union City, New Jersey, was examined on April 20 to 21, 1980, at the request of the New Jersey Department of Labor and Industry. The request was prompted by employee complaints of headache, nausea, dizziness, and fainting. Previous environmental testing failed to identify a causative agent for the symptoms. The air distribution system was evaluated using a constant temperature thermal anemometer. Airflows in enclosed offices were found to vary considerably. In the conference room and other areas, several diffuser grilles were stuck closed or partially closed. Portions of the air supply in enclosed offices tended to flow along the ceiling directly into the ceiling return grilles rather than into the office space. Air movement at 5 feet above the floor varied from about 7 to 20 feet per minute throughout the entire office area. The make up airflow in the public waiting area was also low. The authors recommend that total and make up airflow be increased in those areas where airflow was low, and that specific make up air quantity be determined on the basis of the recommended maximum normal space loading and the rates per person.
