Abstract
In response to a confidential request from employees, an investigation was undertaken of possible hazardous working conditions at the Sterling Van Dyke Credit Union (SIC-6062), Sterling Heights, Michigan. Recurring illnesses were reported among the staff. Employees had reported headaches, backaches, breathing difficulty, purple fingernail beds, disrupted menstrual cycles, asthma, and bronchitis. Two counter flow air handling units serviced the building. Air quality measurements were taken inside and outside the building, and questionnaires dealing with health concerns were distributed to the employees. Contaminants such as environmental tobacco smoke, bioaerosols, and sewer gases were identified as possible causes of employee symptoms. Dry bulb temperatures averaged 75 degrees-F throughout the day with relative humidity levels ranging from 44% to 51%. A peak of 1,800 parts per million was recorded for carbon-dioxide (124389) measured at one location in the early afternoon. The author concludes that deficiencies in the heating, ventilating and air conditioning (HVAC) system may have caused worker complaints. The author recommends that tobacco use be eliminated and improvements be made in the HVAC system.
